Diving in Indonesia: Overview
- Why it’s special: Indonesia sits at the heart of the Coral Triangle and is one of the richest marine biodiversity regions on earth.
- Signature experiences: Muck and macro diving in Ambon and Lembeh, current-swept reefs in Komodo and Alor, hammerheads and sea snakes in the Banda Sea, and pristine coral gardens in Raja Ampat, Wakatobi, Derawan, Bali, and Bunaken.
- Best suited to: Everyone from newer divers in Bali, Bunaken, and Wakatobi to advanced photographers and liveaboard divers in Raja Ampat, Alor, Komodo, and the Banda Sea.
- Best season: Indonesia can be dived year-round, but the best months vary significantly by region. March to October suits many areas, while Raja Ampat and parts of Maluku are often better from October or November through April.
- How to dive it: Resorts work well for Bali, Lembeh, Bunaken, Wakatobi, and parts of Raja Ampat; liveaboards are ideal for remote regions and combination itineraries.
Scuba diving in Indonesia is a must for many serious divers. With an extraordinary concentration of reef fish, corals, macro life, and pelagic encounters, Indonesia is often described as one of the global centres of marine biodiversity. Its position within the Coral Triangle gives divers access to everything from black-sand muck sites and kaleidoscopic reefs to remote seamounts, walls, current dives, manta cleaning stations, and rarely visited liveaboard routes.
Indonesia is also one of the most varied dive destinations in the world. You can spend a week photographing tiny critters in Lembeh, drift over hard-coral gardens in Komodo, look for hammerheads in the Banda Sea, or explore the biodiversity of Raja Ampat aboard a luxury liveaboard. For divers who prefer an easier land-based trip, Bali, Bunaken, Lembeh, and Wakatobi all offer strong resort options.
Over the last decade I’ve led group trips and workshops right across Indonesia, from Bali and Komodo to Raja Ampat, Alor, the Banda Sea, Wakatobi, and Derawan. What keeps me going back is how different each region feels: one week I’m spending entire dives in Lembeh searching for critters the size of a fingernail, the next I’m hanging in the current in Komodo watching mantas and sharks pass by. This guide is based on those trips and on where we actually send guests today, not just on what looks good in a brochure.
For liveaboard divers, Indonesia has some of the best expedition-style diving in the world. Boats such as the Dewi Nusantara, Blue Manta Liveaboard, and Teman liveaboard offer access to some of the country’s most biodiverse and remote regions. For divers looking for something more unusual, trips such as our Halmahera Remote Indonesia Liveaboard Trip – August 2027 explore lesser-known areas with pristine reefs and excellent marine life.

Other Great Dive Areas in Indonesia
Our trip leaders have dived throughout Indonesia and can match you with the right area, dates, boat, or resort at no extra cost.
Email an Indonesia expert
Indonesia is the world’s largest archipelagic country, so new and lesser-known dive areas continue to emerge. Beyond the ten destinations above, divers may also consider Halmahera, Triton Bay, Cenderawasih Bay, the Forgotten Islands, Maumere, Sumbawa, Pulau Weh, and other remote routes across eastern Indonesia.
Some of these regions are best suited to experienced divers or liveaboard travellers, while others work well as add-ons to more established destinations. If you are looking for an off-the-beaten-path itinerary, contact us and we can recommend options based on your dates, budget, and dive experience.
Liveaboards and Dive Resorts in Indonesia
Indonesia offers both excellent liveaboard diving and strong land-based resort options. The right choice depends on how remote you want to go, how much time you have, and whether you prefer a dedicated dive expedition or a more flexible resort stay.
When to Choose a Liveaboard
Liveaboards are ideal for remote regions and combination routes, including Raja Ampat, Komodo, the Banda Sea, Alor, the Forgotten Islands, Halmahera, and some Wakatobi itineraries. They allow you to reach sites that are difficult or impossible to dive from shore.
When to Choose a Dive Resort
Resorts are excellent for Bali, Lembeh, Bunaken, Bangka, Wakatobi, and parts of Raja Ampat. They work well for shorter trips, photographers who want a stable camera setup, divers travelling with non-divers, and guests who prefer more space and flexibility.
Bluewater Travel has extensive experience booking Indonesia dive trips and can help compare liveaboards, resorts, domestic flight routing, seasonal conditions, and itinerary options.

Indonesia Travel Information and Tips
About Indonesia
Indonesia is a vast archipelagic country spread across three time zones: UTC+7 in western Indonesia, UTC+8 in central Indonesia, and UTC+9 in eastern Indonesia. Its main island groups include Sumatra, Java, Kalimantan, Sulawesi, Bali and the Lesser Sunda Islands, Maluku, and Papua.
Red = West Indonesia, yellow = Central Indonesia, green = East Indonesia. Source: Wikimedia Commons.
Most of Indonesia’s best-known dive regions are in central and eastern Indonesia, although Derawan in Kalimantan and Pulau Weh in Sumatra are notable exceptions.
Best Time to Dive Indonesia
Indonesia can be dived year-round, but the best season varies by region. March to October is the classic dry-season window for many destinations, including Bali, Komodo, Bunaken, Lembeh, Alor, and parts of Wakatobi. Raja Ampat is often best from October or November through April, while Banda Sea crossings are highly seasonal and usually scheduled around transition months.
If your dates are fixed, the best strategy is to choose the Indonesian region most likely to have favourable conditions during your travel window.
Weather and Diving Conditions
Indonesia’s climate is tropical, with warm air temperatures year-round. In many regions, May to September is drier and October to April is wetter, but there are important regional exceptions.
Water temperatures are often around 26–29C (79–84F), but there are cooler areas and seasonal upwellings. Nusa Penida in Bali and South Komodo can drop to around 18–24C (64–75F), especially during mola mola or southern Komodo seasons. If you feel the cold, bring a hooded vest or 5mm wetsuit for these areas.
How to Get to Indonesia
Your best international gateway depends on your destination:
- Jakarta (CGK): Often useful for Raja Ampat, Ambon, the Banda Sea, Alor, and many remote eastern Indonesia routes.
- Bali (DPS): Best for Bali, Komodo, Wakatobi, and some connections to other Indonesian regions.
- Manado (MDC): Best for Bunaken, Bangka, Lembeh, and North Sulawesi itineraries.
Domestic flights in Indonesia can be complex, and delays or schedule changes are not uncommon. We recommend building in buffer nights before liveaboards and before international flights. Read our guide to booking domestic flights in Indonesia, or ask your travel advisor before confirming flights.
Other Things to Do in Indonesia
Topside options vary greatly by region. Bali has the widest range of cultural, adventure, dining, and wellness activities. North Sulawesi offers wildlife and nature excursions, including Tangkoko National Park. Remote destinations such as Raja Ampat, Alor, Wakatobi, and the Banda Sea are more dive-focused, though village visits, hiking, snorkelling, kayaking, and birdwatching may be possible.
Bluewater Travel can arrange land-based extensions before or after your dive trip. Contact us if you would like help planning a complete itinerary.

Indonesia Diving FAQs
Is Indonesia suitable for beginner divers?
Yes. Areas such as Bali, Bunaken, Wakatobi, and some resort-based parts of Raja Ampat and Lembeh can be suitable for newer divers. More remote or current-exposed regions such as Alor, the Banda Sea, Komodo, and many Raja Ampat liveaboard routes are better for confident intermediate or advanced divers.
Do I need to join a liveaboard to dive Indonesia?
No. Bali, Lembeh, Bunaken, Bangka, Wakatobi, and parts of Raja Ampat have excellent land-based resorts. Liveaboards are best for remote areas and combination routes such as Raja Ampat north-south itineraries, Banda Sea crossings, Komodo routes, Alor, Halmahera, and the Forgotten Islands.
When is the best time to dive Indonesia?
There is no single best month for all of Indonesia. March to October is excellent for many regions, including Bali, Komodo, Bunaken, Lembeh, and Alor. Raja Ampat is often best from October or November through April. The Banda Sea is highly seasonal, with trips often scheduled around March to May and September to November.
Where is the best macro diving in Indonesia?
Lembeh is the best-known macro and muck destination in Indonesia. Ambon is also outstanding for rare critters, while Bali, Alor, Batanta in Raja Ampat, and parts of South Komodo can also offer excellent macro photography.
Where is the best liveaboard diving in Indonesia?
Raja Ampat, Komodo, the Banda Sea, Alor, Halmahera, the Forgotten Islands, and some Wakatobi routes are among the best liveaboard options. The best choice depends on season, experience level, budget, and whether you prefer reefs, macro, mantas, currents, or remote exploration.
Is Raja Ampat better than Komodo?
They are very different. Raja Ampat is best for coral biodiversity, reef fish, manta rays, and rich reefscapes. Komodo is better for current-swept action, mantas, schooling fish, and dramatic drift dives. Raja Ampat often suits photographers and biodiversity-focused divers, while Komodo appeals to divers who enjoy higher-energy diving.
What experience level do I need for currents in Komodo, Alor, and the Banda Sea?
For current-exposed areas, we recommend Advanced Open Water or equivalent experience, recent dives in current, comfort with deeper water, and strong buoyancy control. Guides can often adapt sites to the group, but many signature dives in these regions are best for intermediate and advanced divers.
What wetsuit should I bring for Indonesia?
For many regions, a 3mm full suit is suitable. If you are diving cooler areas such as Nusa Penida, South Komodo, or sites affected by upwellings, consider a 5mm suit or a hooded vest. Photographers doing long repetitive dives may also prefer slightly more exposure protection.
Is Indonesia good for underwater photography?
Yes. Indonesia is one of the world’s top underwater photography destinations. Lembeh and Ambon are excellent for macro; Raja Ampat, Komodo, Wakatobi, and Alor are outstanding for reefs and wide-angle; and Bali offers a strong mix of wrecks, macro, mantas, and seasonal mola mola.
How many days do I need for an Indonesia dive trip?
For Bali, Lembeh, Bunaken, or Wakatobi, a week can work well. For Raja Ampat, Komodo, Alor, or the Banda Sea, 10 to 14 days is often better once domestic travel and remote logistics are included. For combination trips, plan two weeks or more.
