Q: Can I Dive Komodo While Pregnant?

Pregnancy and Diving in Komodo No — scuba diving during pregnancy is not recommended by any major dive training agency or medical organisation. This applies regardless of the stage of pregnancy. Why Diving During Pregnancy Is Not Safe Fetal DCS risk: The developing baby's circulatory system cannot filter nitrogen bubbles the way an adult's can. Even a dive within safe no-decompression limits for the mother may pose DCS risk to the foetus. Limited research: Ethical constraints prevent controlled studies on pregnant divers, meaning the exact risk level is unknown — but the theoretical risks are serious enough that all experts advise against it. No safe depth: There is no established "safe" depth for pregnant divers. Even shallow dives involve pressure changes that could affect the foetus. Alternative Activities If you are pregnant and travelling to Komodo, you can still enjoy many of the park's highlights: Snorkelling: Surface snorkelling is generally considered safe during pregnancy for healthy women (no pressure changes). Manta Point and Siaba Besar offer excellent snorkelling. Island hopping: Padar Island hike, Pink Beach, dragon trekking (if fitness allows) Boat tours: Enjoy the scenery, watch for dolphins, and relax on deck while your partner dives After Pregnancy Most physicians recommend waiting until after giving birth and completing breastfeeding (or at least until post-partum recovery is complete) before returning to diving. Consult your doctor for personalised advice on when it is safe to resume.

Q: What Sun Protection Do I Need for Diving in Komodo?

Sun Protection for Komodo Diving Labuan Bajo sits at 8° south of the equator , where UV radiation is among the highest on Earth. Sun exposure during long boat rides, surface intervals, and island visits is intense and can cause serious sunburn quickly. Sun Protection Essentials Protection When to Use Notes Reef-safe sunscreen (SPF 50+) Apply before every boat trip and reapply between dives Mineral-based only (zinc oxide or titanium dioxide). Chemical sunscreens damage coral. Rash guard / UV top On the boat and during surface intervals Provides UPF 50+ protection without sunscreen reapplication Wide-brimmed hat On the boat between dives Protects face, ears, and neck — areas most prone to burning UV-protective sunglasses On the boat Glare off the water intensifies UV exposure to eyes Buff / neck gaiter Boat transit and surface intervals Protects neck and can be pulled up to cover face Why Reef-Safe Sunscreen Matters Chemical sunscreens containing oxybenzone and octinoxate are toxic to coral at extremely low concentrations. When thousands of divers and snorkellers enter the water daily, the cumulative impact is significant. Mineral-based sunscreens using zinc oxide and titanium dioxide provide effective UV protection without harming marine life. Common Mistake Many divers apply sunscreen in the morning and forget to reapply. After 2 to 3 hours on a boat, plus salt water and sweat, your initial application has largely washed off. Reapply between every dive and especially before the return transit.

Question 1

Is Diving in Komodo Safe?

Accepted Answer

Diving Safety in Komodo National Park

Komodo diving is safe when approached with the right preparation, equipment, and respect for conditions. The park's strong currents and dynamic conditions require more attention to safety than calm tropical destinations, but the well-established dive industry in Labuan Bajo has decades of experience managing these challenges.

Safety Factors

Factor	Komodo Reality	How Risk Is Managed
Strong currents	The park's defining feature — can be very powerful	Tide table planning, small group sizes (4:1), site selection matched to conditions
Variable visibility	5–40m depending on zone and season	Guides familiar with site conditions, dive briefings address visibility
Cold thermoclines	South Komodo can drop to 19°C	5mm wetsuit recommendations, guide awareness of thermal shock risk
Remote locations	Some sites are 2+ hours from Labuan Bajo	Emergency oxygen on all boats, VHF radio, Siloam Hospital with hyperbaric chamber
Marine life encounters	Sharks, rays, sea snakes present but non-aggressive	Pre-dive briefings on behaviour, respectful distance guidelines

What Makes Komodo Diving Safe

Experienced operators: Labuan Bajo has PADI 5-Star centres with decades of experience guiding divers in these conditions
Small group sizes: Maximum 4 divers per guide at reputable operators
Mandatory SMBs: Surface marker buoys are required at every site for surface identification
Hyperbaric chamber: Siloam Hospital in Labuan Bajo has a multi-place hyperbaric chamber (operational since 2019)
Dive insurance availability: DAN and local insurance options are readily available

When Komodo Diving Becomes Unsafe

The primary risk factors are diver error, overestimation of ability, and ignoring guide instructions. Divers who are honest about their experience level, listen to briefings, follow their guide, and carry appropriate insurance are well-protected by the systems in place.

Key message: Komodo's conditions demand respect, but they do not make diving inherently dangerous. With the right certification, experience, equipment, and a reputable operator, Komodo is a safe and thrilling dive destination.

Question 2

Is There a Hyperbaric Chamber in Labuan Bajo?

Accepted Answer

Hyperbaric Chamber Facilities Near Komodo

Yes — Labuan Bajo has a multi-place hyperbaric chamber at Siloam Hospital, providing critical decompression sickness treatment capacity for the Komodo diving region.

Facility Details

Factor	Komodo Reality	How Risk Is Managed
Strong currents	The park's defining feature — can be very powerful	Tide table planning, small group sizes (4:1), site selection matched to conditions
Variable visibility	5–40m depending on zone and season	Guides familiar with site conditions, dive briefings address visibility

Marine life encounters	Sharks, rays, sea snakes present but non-aggressive	Pre-dive briefings on behaviour, respectful distance guidelines

Before the Chamber Existed

Before Siloam Hospital opened its hyperbaric facility, the nearest chamber was in Bali (Sanglah Hospital) or Makassar, requiring emergency air evacuation — a costly, time-critical, and risky process. The Labuan Bajo chamber has significantly improved the safety profile of diving in the Komodo region.

What Happens in a DCS Emergency

Administer emergency oxygen on the boat (first aid response)
Radio ahead to Siloam Hospital to prepare the chamber
Fastest possible transit back to Labuan Bajo harbour
Road transfer to Siloam Hospital (10–15 minutes from harbour)
Assessment by dive medicine physician and hyperbaric treatment

Cost of Treatment

A single hyperbaric session can cost $1,000 to $5,000 USD. Severe DCS may require multiple sessions over several days, reaching $10,000 to $50,000+ USD. This is why dive insurance is essential — DAN membership covers 100% of hyperbaric treatment costs.

Question 3

Question 4

What Dangerous Marine Life Should I Be Aware of in Komodo?

Accepted Answer

Potentially Dangerous Marine Life in Komodo

Komodo's waters are home to several species that can cause injury if handled or encountered carelessly. However, unprovoked attacks on divers are extremely rare. The vast majority of incidents result from accidental contact, not aggressive behaviour.

Species to Be Aware Of

Factor	Komodo Reality	How Risk Is Managed
Strong currents	The park's defining feature — can be very powerful	Tide table planning, small group sizes (4:1), site selection matched to conditions
Variable visibility	5–40m depending on zone and season	Guides familiar with site conditions, dive briefings address visibility

Marine life encounters	Sharks, rays, sea snakes present but non-aggressive	Pre-dive briefings on behaviour, respectful distance guidelines

First Aid for Marine Life Injuries

Lionfish/stonefish sting: Immerse affected area in hot water (as hot as tolerable, ~45°C) for 30–90 minutes. Seek medical attention.
Jellyfish sting: Remove tentacles with tweezers (not bare hands), rinse with vinegar, apply heat.
Fire coral rash: Rinse with vinegar, apply hydrocortisone cream, take antihistamine.
Blue-ringed octopus bite: Medical emergency — apply pressure immobilisation, call emergency services immediately, begin CPR if breathing stops.

Key rule: The diving glove ban in Komodo exists for a reason. Without gloves, divers instinctively keep their hands away from the reef, which prevents the vast majority of marine life injuries.

Question 5

How Long Should I Wait After Diving Before Flying?

Accepted Answer

No-Fly Times After Diving in Komodo

Waiting an adequate time between your last dive and your flight is essential to prevent decompression sickness (DCS). The reduced cabin pressure in aircraft can cause dissolved nitrogen in your blood to form bubbles, leading to DCS symptoms.

Minimum No-Fly Intervals

Factor	Komodo Reality	How Risk Is Managed
Strong currents	The park's defining feature — can be very powerful	Tide table planning, small group sizes (4:1), site selection matched to conditions

Marine life encounters	Sharks, rays, sea snakes present but non-aggressive	Pre-dive briefings on behaviour, respectful distance guidelines

Practical Planning for Komodo

Most Komodo dive trips involve multiple dives over multiple days, which means the 18 to 24 hour guideline applies. Here are practical scheduling suggestions:

Last dive on Tuesday afternoon → Fly Thursday morning (conservative, recommended)
Last dive on Tuesday afternoon → Fly Wednesday evening (minimum, if 24+ hours have passed)
Never fly the same day as your last dive

What to Do on Your No-Fly Day

Use your mandatory no-fly day to enjoy Labuan Bajo's non-diving activities:

Visit Cunca Wulang waterfall or Rangko Cave
Explore Labuan Bajo's restaurants and night market
Take a sunset boat cruise to see flying foxes
Visit Batu Cermin (Mirror Stone Cave)
Relax at your hotel pool and pack for departure

Critical reminder: This applies to all flights, including short domestic flights from Labuan Bajo to Bali. Even though the flight is only 1 to 1.5 hours, the cabin is pressurised to the equivalent of approximately 2,000 metres altitude — enough to trigger DCS in a recently dived individual.

Question 6

What Vaccinations Do I Need Before Travelling to Komodo?

Accepted Answer

Vaccination and Health Preparation for Komodo

Indonesia is a tropical country, and travelling to Labuan Bajo and Komodo requires some health preparation beyond standard travel to Bali. The region has specific disease risks that visitors should address before departure.

Recommended Vaccinations

Malaria

Labuan Bajo and the Komodo region are in a malaria-transmission zone, confirmed by both the CDC and WHO. Unlike Bali (which is considered low-risk), eastern Indonesia including Flores has active malaria transmission. Antimalarial prophylaxis is recommended.

Common antimalarial medications include atovaquone-proguanil (Malarone), doxycycline, and mefloquine. Consult a travel medicine doctor at least 4 to 6 weeks before departure to determine the best option for you. Some antimalarials need to be started before arrival.

Dengue Fever

Dengue fever is present throughout Indonesia, including Labuan Bajo. There is no preventive medication for dengue — prevention relies on avoiding mosquito bites. Use DEET-based insect repellent, wear long sleeves at dawn and dusk, and sleep under a mosquito net if your accommodation is not fully enclosed.

Diver-Specific Health Note

Some antimalarial medications can have side effects relevant to diving — mefloquine, for example, can cause dizziness and vivid dreams. Discuss your diving plans with your travel medicine doctor when choosing an antimalarial, as some options are better suited to active divers.

Question 7

What Is Decompression Sickness and How Do I Prevent It in Komodo?

Accepted Answer

Decompression Sickness (DCS) Prevention in Komodo

Decompression sickness — commonly called "the bends" — occurs when dissolved nitrogen in your blood and tissues forms bubbles during or after ascent. Komodo's multi-dive days, deep sites, and strong currents make DCS awareness especially important.

DCS Risk Factors Specific to Komodo

Risk Factor	Why It's Relevant in Komodo
Multiple dives per day	3–4 dives daily accumulate nitrogen progressively
Multi-day diving	Liveaboards may involve 4–7 consecutive dive days
Depth	Many popular sites have working depths of 20–30m
Strong currents	Increased exertion raises nitrogen uptake and can cause rapid depth changes
Cold water	South Komodo's cold thermoclines reduce off-gassing efficiency
Dehydration	Tropical heat, sun exposure, and diving are all dehydrating

Prevention Strategies

Use a dive computer: Essential for tracking multi-dive nitrogen loading. Set conservative mode for multi-day trips.
Always do a 3-minute safety stop at 5 metres: This is mandatory protocol on every Komodo dive.
Ascend slowly: Maximum 9 metres per minute (most computers set 10m/min).
Stay hydrated: Drink at least 500ml of water between every dive. Dehydration is one of the biggest modifiable DCS risk factors.
Dive Nitrox: Enriched air reduces nitrogen loading, providing a significant safety margin on multi-dive days.
Plan conservative profiles: Avoid pushing to your no-decompression limits, especially on your 3rd or 4th dive of the day.
Rest day on long trips: Take a no-dive day every 3 to 4 days on extended liveaboard trips.
Avoid alcohol between dives: Alcohol dehydrates and impairs the body's ability to off-gas nitrogen.
No-fly time: Wait at least 18 to 24 hours after your last dive before flying.

DCS Symptoms to Watch For

Joint pain (especially shoulders, elbows, knees)
Tingling or numbness in extremities
Unusual fatigue
Dizziness or vertigo
Skin rash or mottling
Difficulty breathing

If you suspect DCS: Administer emergency oxygen, do not re-enter the water, and get to Siloam Hospital's hyperbaric chamber in Labuan Bajo as quickly as possible. Call DAN Emergency: 0061 8 8212 9242.

Question 8

Dive-Specific Emergency Items

Spare regulators and masks: In case of equipment failure underwater
Cutting tool: For freeing divers from entanglement (line, fishing net)
Throw rope: For surface rescues of divers swept by current
Emergency signalling devices: Whistle, mirror, and flares for attracting attention

What You Should Carry Personally

SMB (Surface Marker Buoy): Your primary personal safety device for surface identification
Whistle or horn: Attached to your BCD for surface signalling
Dive torch: Can be used for emergency signalling in low visibility

Question 9

Is Malaria a Risk in Labuan Bajo and Komodo?

Accepted Answer

Malaria Risk in the Komodo Region

Yes — unlike Bali (which is considered low-risk), the Labuan Bajo and Komodo region is in an active malaria transmission zone. Both the CDC and WHO confirm malaria risk in eastern Indonesia, including Flores island where Labuan Bajo is located.

Malaria Facts for the Komodo Region

Factor	Komodo Reality	How Risk Is Managed
Strong currents	The park's defining feature — can be very powerful	Tide table planning, small group sizes (4:1), site selection matched to conditions
Variable visibility	5–40m depending on zone and season	Guides familiar with site conditions, dive briefings address visibility

Marine life encounters	Sharks, rays, sea snakes present but non-aggressive	Pre-dive briefings on behaviour, respectful distance guidelines

Prevention

Antimalarial medication: Consult a travel medicine doctor 4 to 6 weeks before your trip. Common options include atovaquone-proguanil (Malarone), doxycycline, and mefloquine.
Insect repellent: Use DEET-based repellent (20–50% concentration) on exposed skin, especially at dawn and dusk.
Clothing: Wear long sleeves and trousers in the evening when mosquitoes are most active.
Accommodation: Sleep in rooms with screens, air conditioning, or mosquito nets.
Liveaboard note: On liveaboards anchored offshore, mosquito exposure is lower than on land. However, island visits (dragon trekking on Rinca) bring you into mosquito habitat.

Diver-Specific Consideration

Some antimalarial medications have side effects that may affect diving:

Medication	Diver Considerations
Atovaquone-proguanil (Malarone)	Generally well-tolerated; few diving-related concerns
Doxycycline	Can increase sun sensitivity (relevant in equatorial diving); take with food
Mefloquine (Lariam)	Can cause dizziness, anxiety, vivid dreams — potentially problematic for diving

Our recommendation: Atovaquone-proguanil (Malarone) is generally the preferred choice for divers due to its minimal side effect profile. Discuss with your travel doctor.

Question 10

What Should I Do If I Get Stung by a Jellyfish or Lionfish in Komodo?

Accepted Answer

Marine Sting First Aid in Komodo

Marine life stings are uncommon in Komodo but can occur, especially when divers accidentally brush against reef organisms. Knowing the correct first aid response is important.

First Aid by Sting Type

Risk Factor	Why It's Relevant in Komodo
Multiple dives per day	3–4 dives daily accumulate nitrogen progressively
Multi-day diving	Liveaboards may involve 4–7 consecutive dive days
Depth	Many popular sites have working depths of 20–30m
Strong currents	Increased exertion raises nitrogen uptake and can cause rapid depth changes
Cold water	South Komodo's cold thermoclines reduce off-gassing efficiency
Dehydration	Tropical heat, sun exposure, and diving are all dehydrating

Prevention

Wear a full wetsuit: Provides a barrier against jellyfish tentacles, fire coral, and minor spine contact
Maintain excellent buoyancy: Most sting injuries result from accidental reef contact due to poor buoyancy
Never touch or handle marine life: The glove ban in Komodo helps reinforce this instinct
Watch where you put your hands and feet: Especially when entering and exiting the water from the boat

Hot Water Protocol

For venomous spine injuries (lionfish, stonefish, stingray), hot water is the most effective first aid. The venom proteins are denatured by heat. Water should be as hot as the patient can tolerate (approximately 45°C) without causing burns. Most dive boats carry a thermos of hot water specifically for this purpose.

Question 11

What Are the Biggest Diving Risks in Komodo?

Accepted Answer

Primary Diving Risks in Komodo and How to Manage Them

Understanding the specific risks of Komodo diving — and how to mitigate them — is the foundation of a safe trip.

Risk Assessment

Risk Factor	Why It's Relevant in Komodo
Multiple dives per day	3–4 dives daily accumulate nitrogen progressively
Multi-day diving	Liveaboards may involve 4–7 consecutive dive days
Depth	Many popular sites have working depths of 20–30m
Strong currents	Increased exertion raises nitrogen uptake and can cause rapid depth changes
Cold water	South Komodo's cold thermoclines reduce off-gassing efficiency
Dehydration	Tropical heat, sun exposure, and diving are all dehydrating

The Single Biggest Risk

The single most common serious risk in Komodo is being separated from the group in strong current. This is manageable through simple protocols: always carry an SMB, stay close to your guide, maintain visual contact with your buddy, and do not wander away from the group to photograph something alone. An SMB deployed on the surface makes you visible to the boat from hundreds of metres away.

Risk Mitigation Checklist

Carry and know how to use your SMB
Dive with a reputable operator (max 4:1 ratio)
Listen to every pre-dive briefing carefully
Be honest about your experience level
Carry dive insurance
Stay hydrated
Use a dive computer
Respect your limits — abort any dive you are uncomfortable with

Question 12

Can I Dive Komodo If I Have Asthma?

Accepted Answer

Diving with Asthma in Komodo

Asthma is one of the most common medical conditions flagged on the RSTC diving medical questionnaire. Whether you can dive with asthma depends on the type, severity, and how well it is controlled.

Asthma and Diving: General Guidelines

Factor	Komodo Reality	How Risk Is Managed
Strong currents	The park's defining feature — can be very powerful	Tide table planning, small group sizes (4:1), site selection matched to conditions
Variable visibility	5–40m depending on zone and season	Guides familiar with site conditions, dive briefings address visibility
Cold thermoclines	South Komodo can drop to 19°C	5mm wetsuit recommendations, guide awareness of thermal shock risk
Remote locations	Some sites are 2+ hours from Labuan Bajo	Emergency oxygen on all boats, VHF radio, Siloam Hospital with hyperbaric chamber
Marine life encounters	Sharks, rays, sea snakes present but non-aggressive	Pre-dive briefings on behaviour, respectful distance guidelines

Why Asthma Is a Concern for Diving

The primary risk is air trapping. If an asthma attack occurs at depth, the airways narrow, trapping air in the lungs. During ascent, this trapped air expands, potentially causing a lung overexpansion injury (pulmonary barotrauma) — one of the most serious diving emergencies.

Getting Cleared to Dive

If you have asthma and want to dive Komodo, you need a written clearance from a physician — ideally one trained in dive medicine. Bring this letter with you, as your dive centre will require it at registration. The physician will likely assess lung function, exercise tolerance, and asthma management history before clearing you.

Komodo-Specific Considerations

Cold water: South Komodo's cold thermoclines (19–22°C) can trigger bronchospasm in cold-sensitive asthmatics
Physical exertion: Swimming against Komodo's currents is strenuous and can trigger exercise-induced asthma
Depth: The denser air breathed at depth can make an asthma episode more severe

Our advice: If you have asthma and want to dive Komodo, consult a dive medicine specialist before your trip. Be completely honest about your condition on the medical form. Dive centres that take this seriously are protecting your safety.

Question 13

How Do I Contact Emergency Services from Komodo?

Accepted Answer

Emergency Contacts for Komodo Diving

Having the right emergency numbers saved in your phone before your trip can save critical time in an emergency. Here are the key contacts for Komodo.

Essential Emergency Numbers

Risk Factor	Why It's Relevant in Komodo
Multiple dives per day	3–4 dives daily accumulate nitrogen progressively
Multi-day diving	Liveaboards may involve 4–7 consecutive dive days
Depth	Many popular sites have working depths of 20–30m
Strong currents	Increased exertion raises nitrogen uptake and can cause rapid depth changes
Cold water	South Komodo's cold thermoclines reduce off-gassing efficiency
Dehydration	Tropical heat, sun exposure, and diving are all dehydrating

What to Do in a Dive Emergency

Administer emergency oxygen from the boat's DAN kit
Call DAN Emergency Hotline — they provide immediate medical advice and coordinate treatment
Radio ahead to Siloam Hospital to prepare the hyperbaric chamber (boat crew handles this)
Transit to Labuan Bajo harbour as fast as safely possible
Transfer to Siloam Hospital by road (10–15 minutes from harbour)

Communication at Sea

Mobile phone signal is patchy to non-existent at many offshore dive sites. Dive boats rely on VHF marine radio for emergency communication. Ensure your boat has a working VHF radio — this is a non-negotiable safety requirement.

Pre-trip action: Save the DAN and Siloam numbers in your phone before your trip. Share your dive schedule and operator contact details with a family member at home.

Question 14

Is the Water Safe to Drink in Labuan Bajo?

Accepted Answer

Drinking Water Safety in Labuan Bajo

Tap water in Labuan Bajo (and throughout Indonesia) is not safe to drink. Always use bottled or filtered water for drinking and brushing teeth.

Staying Hydrated in Komodo

Hydration is critical for diving safety — dehydration increases the risk of DCS and reduces physical performance. Tips:

Drink at least 3 litres of water per day when diving in tropical conditions
Bring a reusable water bottle and refill at hotels or dive centres with filtration systems
Avoid excessive alcohol the night before diving — it dehydrates significantly
Electrolyte tablets or sachets help replace minerals lost through sweating

Question 15

What Happened to the Tourist Boat That Sank Near Komodo in 2025?

Accepted Answer

December 2025 Boat Incident Near Komodo: What Divers Should Know

In December 2025, the sightseeing boat KM Putri Sakinah sank between Komodo and Padar Island, resulting in the deaths of 4 Spanish tourists. This incident raised safety concerns among travellers planning Komodo visits. Here are the facts.

Incident Summary

Factor	Komodo Reality	How Risk Is Managed
Strong currents	The park's defining feature — can be very powerful	Tide table planning, small group sizes (4:1), site selection matched to conditions

Marine life encounters	Sharks, rays, sea snakes present but non-aggressive	Pre-dive briefings on behaviour, respectful distance guidelines

Key Context for Divers

This was a sightseeing boat, not a dive boat. The vessel was a general tourist transfer boat, not operated by a recognised dive centre.
Dive boats have different safety standards. Reputable Labuan Bajo dive operators maintain well-serviced engines, carry comprehensive safety equipment (life rafts, oxygen, VHF radio), and employ experienced captains and crew.
PADI 5-Star and SSI Diamond centres are subject to regular safety audits and equipment maintenance requirements.

Lessons for Travellers

Choose your operator carefully — whether for diving, island hopping, or transit
Verify that any boat you board has life jackets, a radio, and basic safety equipment
Avoid overloaded vessels — a common issue with budget tourist boats
Check weather conditions before any boat trip, especially during wet season

Perspective: Thousands of divers visit Komodo safely every month on well-maintained dive vessels operated by experienced professionals. The December 2025 incident involved a different class of vessel entirely. Choosing a reputable dive operator significantly reduces your risk.

Question 16

Can I Dive Komodo While Pregnant?

Accepted Answer

Pregnancy and Diving in Komodo

No — scuba diving during pregnancy is not recommended by any major dive training agency or medical organisation. This applies regardless of the stage of pregnancy.

Why Diving During Pregnancy Is Not Safe

Fetal DCS risk: The developing baby's circulatory system cannot filter nitrogen bubbles the way an adult's can. Even a dive within safe no-decompression limits for the mother may pose DCS risk to the foetus.
Limited research: Ethical constraints prevent controlled studies on pregnant divers, meaning the exact risk level is unknown — but the theoretical risks are serious enough that all experts advise against it.
No safe depth: There is no established "safe" depth for pregnant divers. Even shallow dives involve pressure changes that could affect the foetus.

Alternative Activities

If you are pregnant and travelling to Komodo, you can still enjoy many of the park's highlights:

Snorkelling: Surface snorkelling is generally considered safe during pregnancy for healthy women (no pressure changes). Manta Point and Siaba Besar offer excellent snorkelling.
Island hopping: Padar Island hike, Pink Beach, dragon trekking (if fitness allows)
Boat tours: Enjoy the scenery, watch for dolphins, and relax on deck while your partner dives

After Pregnancy

Most physicians recommend waiting until after giving birth and completing breastfeeding (or at least until post-partum recovery is complete) before returning to diving. Consult your doctor for personalised advice on when it is safe to resume.

Question 17

How Do Komodo Dive Operators Handle Current-Related Emergencies?

Accepted Answer

Current Emergency Protocols in Komodo

Current-related incidents — primarily diver separation from the group — are the most common emergency scenario in Komodo. Reputable operators have well-practised protocols for managing these situations.

Prevention Measures

Factor	Komodo Reality	How Risk Is Managed
Strong currents	The park's defining feature — can be very powerful	Tide table planning, small group sizes (4:1), site selection matched to conditions
Variable visibility	5–40m depending on zone and season	Guides familiar with site conditions, dive briefings address visibility
Cold thermoclines	South Komodo can drop to 19°C	5mm wetsuit recommendations, guide awareness of thermal shock risk
Remote locations	Some sites are 2+ hours from Labuan Bajo	Emergency oxygen on all boats, VHF radio, Siloam Hospital with hyperbaric chamber
Marine life encounters	Sharks, rays, sea snakes present but non-aggressive	Pre-dive briefings on behaviour, respectful distance guidelines

If a Diver Gets Separated

Underwater: Diver looks for the group for 1 minute. If not found, ascend slowly to 5 metres, deploy SMB, complete safety stop, then surface.
On the surface: Inflate BCD fully, hold SMB upright, blow whistle or sound horn, and wait for the boat. Do NOT swim against the current to find the boat — stay visible and let the boat come to you.
Boat response: The boat captain and lookout scan for SMBs and bubbles continuously. The tender boat is deployed immediately to collect any separated diver.
Extended separation: If a diver cannot be located quickly, the captain initiates a search pattern and radios other boats in the area for assistance. Coast guard is contacted if needed.

What Divers Should Know

Being swept away from your group, while alarming, is manageable if you have your SMB, a whistle, and an inflated BCD
The boat WILL find you — your SMB is visible from several hundred metres
Do NOT panic, do NOT fight the current, and do NOT exhaust yourself swimming
Most separation incidents are resolved within 5 to 15 minutes

Labuan Bajo sits at 8° south of the equator, where UV radiation is among the highest on Earth. Sun exposure during long boat rides, surface intervals, and island visits is intense and can cause serious sunburn quickly.

Sun Protection Essentials

Factor	Komodo Reality	How Risk Is Managed
Strong currents	The park's defining feature — can be very powerful	Tide table planning, small group sizes (4:1), site selection matched to conditions
Variable visibility	5–40m depending on zone and season	Guides familiar with site conditions, dive briefings address visibility
Cold thermoclines	South Komodo can drop to 19°C	5mm wetsuit recommendations, guide awareness of thermal shock risk
Remote locations	Some sites are 2+ hours from Labuan Bajo	Emergency oxygen on all boats, VHF radio, Siloam Hospital with hyperbaric chamber
Marine life encounters	Sharks, rays, sea snakes present but non-aggressive	Pre-dive briefings on behaviour, respectful distance guidelines

Why Reef-Safe Sunscreen Matters

Chemical sunscreens containing oxybenzone and octinoxate are toxic to coral at extremely low concentrations. When thousands of divers and snorkellers enter the water daily, the cumulative impact is significant. Mineral-based sunscreens using zinc oxide and titanium dioxide provide effective UV protection without harming marine life.

Common Mistake

Many divers apply sunscreen in the morning and forget to reapply. After 2 to 3 hours on a boat, plus salt water and sweat, your initial application has largely washed off. Reapply between every dive and especially before the return transit.

Question 19

Can I Dive in Komodo If I Take Regular Medication?

Accepted Answer

Diving on Medication in Komodo

Many common medications are compatible with scuba diving, but some require careful consideration. The key question is whether the medication — or the condition it treats — affects your ability to dive safely.

Common Medications and Diving

Risk Factor	Why It's Relevant in Komodo
Multiple dives per day	3–4 dives daily accumulate nitrogen progressively
Multi-day diving	Liveaboards may involve 4–7 consecutive dive days
Depth	Many popular sites have working depths of 20–30m
Strong currents	Increased exertion raises nitrogen uptake and can cause rapid depth changes
Cold water	South Komodo's cold thermoclines reduce off-gassing efficiency
Dehydration	Tropical heat, sun exposure, and diving are all dehydrating

What to Do

Consult a dive medicine physician before your trip about all regular medications
Disclose all medications on the RSTC medical questionnaire — do not omit anything
Bring sufficient supply for your entire trip plus extras (medication may not be available in Labuan Bajo)
Carry medication in original packaging with pharmacy labels for customs and medical identification

Question 20

What Are the Signs of Decompression Sickness and What Should I Do?

Accepted Answer

Recognising and Responding to Decompression Sickness

Knowing the signs of DCS and how to respond can mean the difference between a full recovery and lasting injury. DCS can appear within minutes to 48 hours after a dive, with most cases presenting within 6 hours.

DCS Symptoms by Type

Factor	Komodo Reality	How Risk Is Managed
Strong currents	The park's defining feature — can be very powerful	Tide table planning, small group sizes (4:1), site selection matched to conditions
Variable visibility	5–40m depending on zone and season	Guides familiar with site conditions, dive briefings address visibility
Cold thermoclines	South Komodo can drop to 19°C	5mm wetsuit recommendations, guide awareness of thermal shock risk
Remote locations	Some sites are 2+ hours from Labuan Bajo	Emergency oxygen on all boats, VHF radio, Siloam Hospital with hyperbaric chamber
Marine life encounters	Sharks, rays, sea snakes present but non-aggressive	Pre-dive briefings on behaviour, respectful distance guidelines

What to Do If You Suspect DCS

Stop diving immediately — do not re-enter the water under any circumstances
Administer 100% emergency oxygen — continuous flow from the boat's DAN kit
Lie down — horizontal position preferred, or recovery position if nauseated
Hydrate — drink water if conscious and able to swallow
Call DAN Emergency: 0061 8 8212 9242 — they provide immediate medical guidance
Transport to Siloam Hospital — fastest possible route to the hyperbaric chamber
Do NOT fly — altitude worsens DCS dramatically

When to Be Suspicious

Any unusual symptom after diving should be treated as potential DCS until proven otherwise. Pain that you might normally attribute to "a tough dive" or "sleeping funny" could be DCS, especially if it appeared after diving. When in doubt, seek assessment — early treatment leads to better outcomes.

Question 21

How Do I Stay Safe from Mosquito-Borne Diseases in Komodo?

Accepted Answer

Preventing Mosquito-Borne Illness in the Komodo Region

Both malaria and dengue fever are present in the Labuan Bajo and Komodo area. Protecting yourself from mosquito bites is an important part of your health preparation.

Disease Risks

Marine life encounters	Sharks, rays, sea snakes present but non-aggressive	Pre-dive briefings on behaviour, respectful distance guidelines

Bite Prevention Strategies

DEET-based insect repellent (20–50%): Apply to exposed skin at dawn, dusk, and during island visits. Reapply every 4–6 hours.
Long sleeves and trousers: Especially in the evening in Labuan Bajo and during island treks on Rinca
Accommodation with screens or A/C: Air conditioning deters mosquitoes; ensure windows and doors have screens
Mosquito coils or plug-in devices: Available at local shops; useful for open-air dining

Liveaboard vs. Land-Based Risk

Mosquito exposure is significantly lower on a liveaboard anchored offshore than in town-based accommodation. However, island visits (Rinca dragon trek, Pink Beach) bring you into mosquito habitat. Apply repellent before going ashore.

Question 22

What Should I Do If I Feel Unwell Before a Dive in Komodo?

Accepted Answer

Diving When You Feel Unwell: Guidance for Komodo

If you are feeling unwell before a dive, the safest approach is to err on the side of caution and skip the dive. Komodo's conditions demand physical and mental readiness, and diving while unwell can be dangerous.

When to Skip a Dive

Factor	Komodo Reality	How Risk Is Managed
Strong currents	The park's defining feature — can be very powerful	Tide table planning, small group sizes (4:1), site selection matched to conditions

Communicating with Your Operator

Tell your guide honestly how you feel — they will not pressure you to dive
If you skip a dive on a multi-day package, ask about rescheduling options
You can usually stay on the boat and snorkel instead of diving

Golden rule: If you are unsure whether you should dive, do not dive. No single dive is worth risking your health. Komodo will still be here when you feel better.

Question 23

Are There Any Ear Problems I Should Watch For When Diving Komodo?

Accepted Answer

Ear Health for Komodo Diving

Ear problems are the most common medical issue affecting recreational divers, and Komodo's conditions — negative entries, multiple daily dives, and cold thermoclines — can increase the risk.

Common Ear Issues

Marine life encounters	Sharks, rays, sea snakes present but non-aggressive	Pre-dive briefings on behaviour, respectful distance guidelines

Preventive Ear Care

Dry your ears after every dive: Tilt your head and gently pull your earlobe to drain water. A towel corner or dedicated ear-drying drops help.
Preventive ear drops: A mixture of half rubbing alcohol and half white vinegar, applied after each dive, dries the ear canal and prevents bacterial growth.
Do not use cotton buds: They push debris deeper and can damage the ear canal.
Pre-equalise before entry: Gently equalise on the surface before negative entries to open eustachian tubes.

If you experience ear pain during a dive: Stop descending, signal your guide, ascend slightly, and try to equalise. If it does not resolve, abort the dive. Continuing to dive with ear pain risks a ruptured eardrum.

Question 24

Is There a Hospital Near Komodo National Park?

Accepted Answer

Medical Facilities Near Komodo

The primary medical facility serving the Komodo diving region is Siloam Hospital in Labuan Bajo. For serious medical emergencies beyond its capabilities, evacuation to Bali is the standard protocol.

Medical Facilities

Factor	Komodo Reality	How Risk Is Managed
Strong currents	The park's defining feature — can be very powerful	Tide table planning, small group sizes (4:1), site selection matched to conditions
Variable visibility	5–40m depending on zone and season	Guides familiar with site conditions, dive briefings address visibility

Marine life encounters	Sharks, rays, sea snakes present but non-aggressive	Pre-dive briefings on behaviour, respectful distance guidelines

Limitations

Labuan Bajo is a small town in eastern Indonesia. While Siloam Hospital has improved medical capacity significantly (especially with the hyperbaric chamber), it does not have the specialist resources of a major city hospital. Serious non-diving medical emergencies (major trauma, heart attack, stroke) may require air evacuation to Bali's Sanglah Hospital or BIMC Hospital.

Insurance Importance

This is why comprehensive travel and dive insurance with medical evacuation coverage is essential. Air ambulance evacuation from Labuan Bajo to Bali can cost $10,000 to $30,000+ USD without insurance.

Pharmacy Availability

Basic pharmacies (apotek) in Labuan Bajo stock common medications including pain relief, antibiotics, antihistamines, and seasickness tablets. However, specialised or prescription medications may not be available — bring a full supply of any regular medication from home.

Question 25

How Do I Prevent Seasickness on Komodo Dive Trips?

Accepted Answer

Seasickness Prevention for Komodo Diving

Seasickness is common on Komodo dive trips due to the 1.5 to 2.5-hour boat transits and sometimes choppy conditions. Proactive prevention is key.

Prevention Methods Ranked by Effectiveness

Marine life encounters	Sharks, rays, sea snakes present but non-aggressive	Pre-dive briefings on behaviour, respectful distance guidelines

Diver-Specific Considerations

Some seasickness medications cause drowsiness, which can impair diving performance and increase risk. When choosing a medication:

Preferred for divers: Meclizine (less drowsy), ginger
Use with caution: Dimenhydrinate (can cause drowsiness)
Discuss with dive doctor: Scopolamine patch (effective but has side effects)

Timing Is Everything

Most seasickness medications are preventive, not curative. Once you feel nauseous, medication is far less effective. Take your chosen medication 30 to 60 minutes before boarding — not when symptoms start.

Question 26

What Should I Know About Diving Safety During the Wet Season in Komodo?

Accepted Answer

Wet Season Safety Considerations for Komodo Diving

The wet season (December–March) brings specific safety factors that differ from the dry season. Being aware of these helps you prepare and stay safe.

Wet Season Safety Factors

Risk Factor	Why It's Relevant in Komodo
Multiple dives per day	3–4 dives daily accumulate nitrogen progressively
Multi-day diving	Liveaboards may involve 4–7 consecutive dive days
Depth	Many popular sites have working depths of 20–30m
Strong currents	Increased exertion raises nitrogen uptake and can cause rapid depth changes
Cold water	South Komodo's cold thermoclines reduce off-gassing efficiency
Dehydration	Tropical heat, sun exposure, and diving are all dehydrating

Advantages of Wet Season Safety

Fewer boats: Reduced tourist numbers mean less crowding at dive sites and less boat traffic
Experienced divers: Wet season attracts more experienced divers, meaning your group is likely well-matched
Calmer south sites: While the north is rough, south Komodo is often calmer during NW monsoon

Question 27

Can I Dive Komodo with Diabetes?

Accepted Answer

Diving with Diabetes in Komodo

Diving with diabetes is possible but requires careful management, physician clearance, and specific protocols. Both Type 1 and Type 2 diabetics can dive in Komodo under the right conditions.

Requirements for Diving with Diabetes

Factor	Komodo Reality	How Risk Is Managed
Strong currents	The park's defining feature — can be very powerful	Tide table planning, small group sizes (4:1), site selection matched to conditions
Variable visibility	5–40m depending on zone and season	Guides familiar with site conditions, dive briefings address visibility
Cold thermoclines	South Komodo can drop to 19°C	5mm wetsuit recommendations, guide awareness of thermal shock risk
Remote locations	Some sites are 2+ hours from Labuan Bajo	Emergency oxygen on all boats, VHF radio, Siloam Hospital with hyperbaric chamber
Marine life encounters	Sharks, rays, sea snakes present but non-aggressive	Pre-dive briefings on behaviour, respectful distance guidelines

Komodo-Specific Considerations

Physical exertion: Swimming in Komodo's currents is demanding and can drop blood sugar levels unexpectedly
Multiple daily dives: Three to four dives per day require careful glucose monitoring between each dive
Remote location: Medical facilities are limited. Carry your own glucose meter, insulin, and hypo treatment.
Heat and dehydration: Tropical conditions affect blood sugar regulation. Stay well hydrated.

Protocol for Each Dive Day

Test blood glucose before each dive — do not dive if below 8.3 mmol/L (150 mg/dL)
Eat a carbohydrate snack before each dive
Carry fast-acting glucose on the boat (juice, glucose tablets)
Inform your guide of your condition and the signs of hypoglycaemia
Test blood glucose after each dive and before meals

Question 28

What Travel Insurance Should I Get for a Komodo Dive Trip?

Accepted Answer

Choosing Travel Insurance for Komodo Diving

You need two types of coverage for a Komodo dive trip: general travel insurance and dive-specific insurance. Here is how to ensure you are fully protected.

Coverage You Need

Factor	Komodo Reality	How Risk Is Managed
Strong currents	The park's defining feature — can be very powerful	Tide table planning, small group sizes (4:1), site selection matched to conditions
Variable visibility	5–40m depending on zone and season	Guides familiar with site conditions, dive briefings address visibility
Cold thermoclines	South Komodo can drop to 19°C	5mm wetsuit recommendations, guide awareness of thermal shock risk
Remote locations	Some sites are 2+ hours from Labuan Bajo	Emergency oxygen on all boats, VHF radio, Siloam Hospital with hyperbaric chamber
Marine life encounters	Sharks, rays, sea snakes present but non-aggressive	Pre-dive briefings on behaviour, respectful distance guidelines

What to Verify in Your Policy

Scuba diving is explicitly covered — many standard travel policies exclude diving or only cover to 18m
Depth coverage extends to 40m — Komodo's advanced sites reach 30–40m
Decompression treatment is covered — specifically named, not excluded as "hazardous activity"
Indonesia is a covered destination
Medical evacuation coverage is included — with sufficient limits for air ambulance

Our Recommended Approach

DAN annual membership + general travel insurance = comprehensive coverage. DAN provides gold-standard dive accident coverage including instant hyperbaric chamber admission, while general travel insurance covers everything else (trip cancellation, non-dive medical issues, luggage, delays).

Cost of Being Uninsured

Emergency	Cost Without Insurance
Single hyperbaric session	$1,000–5,000
Multi-day DCS treatment	$10,000–50,000+
Air ambulance to Bali	$10,000–30,000+
International medical evacuation	$50,000–100,000+

Annual DAN membership costs approximately $75 USD — a fraction of a single hyperbaric session. There is no rational reason to dive Komodo without insurance.

Question 29

How Do I Prepare Mentally for Strong Current Diving in Komodo?

Accepted Answer

Mental Preparation for Komodo's Currents

Komodo's strong currents are the element that most differentiates it from calm tropical destinations. Mental preparedness is just as important as physical fitness and technical skills.

Common Fears and Realistic Perspectives

Factor	Komodo Reality	How Risk Is Managed
Strong currents	The park's defining feature — can be very powerful	Tide table planning, small group sizes (4:1), site selection matched to conditions
Variable visibility	5–40m depending on zone and season	Guides familiar with site conditions, dive briefings address visibility

Marine life encounters	Sharks, rays, sea snakes present but non-aggressive	Pre-dive briefings on behaviour, respectful distance guidelines

Mental Preparation Strategies

Visualise success: Before each dive, mentally walk through the dive plan — entry, descent, reef exploration, safety stop, exit. Visualisation builds confidence.
Control your breathing: On the surface before entry, take 5 slow, deep breaths. Calm breathing on the surface translates to calm breathing underwater.
Trust your guide: Komodo's guides have done thousands of dives in these conditions. They will not put you in danger.
Start easy: Request calm sites for your first 1–2 dives. Build confidence before tackling Castle Rock or Batu Bolong.
Accept that current is normal: Komodo's currents are a feature, not a bug. They create the marine life encounters that make this destination world-class.

The experienced diver's perspective: Most divers who initially feel anxious about Komodo's currents describe drift diving as one of the most exhilarating experiences of their diving career by the end of their trip. The transition from anxiety to confidence happens quickly with good guidance and progressive site selection.

Question 30
