Liveaboards in Indonesia Liveaboard overview

Imagine diving in a destination where there are so many islands to discover that you simply never run out of new places to dive. That’s Indonesia, and with more than 18,000 islands in the archipelago, you can be sure that there are always opportunities to explore somewhere new on a liveaboard trip.

If you’re wondering what you might discover, the list is long: Komodo offers a chance to swim with manta rays and experience exhilarating currents while Raja Ampat lets you marvel at beautiful healthy soft coral reefs while looking for pelagic species. Lesser-known areas like the Banda Sea let you swim with schooling hammerhead sharks and even explore underwater volcanoes.

Ambon and Alor, Cenderawasih Bay, Raja Ampat, Triton Bay—the list of must-visit destinations in Indonesia goes on and on.

The eastern islands of Indonesia are known as the Coral Triangle or the “species factory,” simply because you can find nearly 500 species of hard and soft coral here and thousands of fish species, everything from psychedelic frogfish to schooling jacks, manta rays, and sharks.

Indonesia truly has it all—a range of biodiversity that is hard to find elsewhere. The best way to explore this wide-ranging destination is on a liveaboard, largely because many sites are only accessible by boat.

There are over 70 liveaboards operating in Indonesia, so there are plenty of excellent choices not mentioned here—that said, let’s dive into our overviews of the top 10 liveaboards in Indonesia.

Indonesia is a year-round dive destination, but as you might expect with a country so vast, different areas are better seasonally. No matter when and where you go, expect warm air temperatures. The tropical climate keeps it between around 73 and 91 F (23 to 33 C) year-round. Water temperatures fluctuate similarly, ranging from around 78 to 84 F (26 to 29 C). The dry season is roughly from April through October, which makes for better visibility and cooler water temperatures.

When it comes to dive seasons though, the best time to visit Raja Ampat is roughly November through April. From May through October, most liveaboards move to Komodo and/or Alor.

Indonesia is made up of thousands of volcanic islands—is a huge nation that is home to hundreds and hundreds of different ethnic groups that speak all different languages. From its unique beaches to awesome volcanoes, to jungles overflowing with wildlife, to an underwater world teeming with marine life, Indonesia offers something for every kind of traveler.

With thousands of dive sites to choose from and everything from muck diving to megafauna spotting, it’s best to get a general idea of what you want to see before you choose a liveaboard. Different regions offer different types of diving, and during different seasons, so start by deciding when and where you want to go:

There’s something for everyone in legendary Komodo. Dramatic walls and canyons are draped with vibrant corals, and exhilarating drift dives will leave your adrenalin pumping. Rather take your time? No problem—there are world-class macro dives, too, where you can hunt for the ocean’s most elusive tiny critters.

One of the highlights in Komodo is the chance to see oceanic mantas at several well-known sites like Manta Point, Batu Bolong, and Makassar Reef. The best time to dive Komodo is April through November.

Remote Raja Ampat, which means “Four Kings,” is tucked into the West Papua province of eastern Indonesia. The ‘four kings’ refer to the islands of Misool, Batanta, Waigeo and Salawati, but it’s the underwater realm that truly astonishes here.

You’ll get the chance to spot both smaller critters and pelagics, but the true star here is a pristine reef, bursting with color, life, diversity, and abundance. Highlights include everything from pygmy seahorses to wobbegong sharks. World famous dive site Cape Kri holds the record for the largest number of species ever spotted on a single dive. The best time to dive Raja Ampat is October to April.

Alor and Flores remain somewhat undiscovered treasures, although many liveaboards are catching on and adding these destinations to their itineraries. Expect a bit of a grab bag, with vibrant, coral-encrusted walls, current-swept pinnacles, and sandy slopes perfect for muck diving.

Search hard-coral gardens for the bucket-list rhinopias fish, or keep your eye on the blue for passing pelagics. Year-round diving is possible here, with dry season running May through November and rainy season from ­December through April.

Speaking of undiscovered treasures, a liveaboard trip to the Banda Sea delivers delights galore. Covering 182,000 square miles (470,000 square km), the Banda sea stretches between Sulawesit, East Timor, and Papua New Guinea. The Maluku Islands—also known as the Forgotten Islands—dot the water like pristine green gems, and the underwater landscape is just as untouched.

Sitting right in the middle of the Coral Triangle, the marine realm promises exploratory diving with stunning coral landscapes, hammerhead cleaning stations, huge schools of fish, and plenty of macro diving. There are two distinct dive seasons, falling between the monsoons. Plan your visit from April to May or September to November.

Southeast Sulawesi is home to stunning coral reefs, colorful walls, plentiful macro life, pinnacles, and occasional pelagics. North Sulawesi, though less frequently visited by liveaboards, is home to legendary Lembeh, the world’s epicenter for finding the wacky and weird while macro diving. Nearby Bunaken offers turtles, trevally, and more stunning coral life.

The best time to dive  Sulawesi is during the dry season from July through October. Diving is still possible during the shoulder season (March-April and November-December), but you should expect rainy conditions and reduced visibility.
