Scuba Diving Indonesia

At a glance, Indonesia can appear to be an intimidatingly large country which could be problematic to travel through with poor transportation links, little infrastructure, unreliable communications and below par accommodation in remote regions. However, with El Aleph we make the Indonesian Archipelago and scuba diving Indonesia more accessible and luxurious than ever before.

Coral Reefs in Indonesia

Indonesia is quite unique in that it boasts all manner of reefs on which to dive; fringing reefs, barrier reefs and atolls are all spread across the archipelago. Difficulty levels vary enormously from shallow, clear lagoons with little current through to deep, open sea pinnacles with surface waves and adrenaline pumping currents. Indonesian reefs boast over 500 species of coral, 10,000 species of invertebrates and sea plants and over 3,000 species of fish. They are home to 6 out of 7 of the World’s turtle species and form part of the migratory routes of over 30 species of marine mammals. Indonesian waters also accommodate more than one third of all whale and dolphin species and support the most varied and abundant marine life on Earth.

The Best Regions for Scuba Diving Indonesia

There is certainly no shortage of incredible options when you are trying to decide where to go diving in Indonesia. Here a few of our top picks:

Banda islands Indonesia ocean surrounded by hills.

The Banda Sea

The Banda Sea is one of the best areas for those who want to see sea snakes or hammerheads while scuba diving Indonesia.

Most of the diving around the Banda Sea involves excellent wall dives, and great macro sites, but the biggest draws are the resident sea snakes at Manuk and Gunung Api islands, and the chance to see schooling hammerheads.

In addition to incredible marine life, cruising and diving in the Banda Sea delivers excellent visibility and dramatic topography. The region is remote and only accessible by water – it’s an ideal cruising destination for divers and you’ll also enjoy lush vibrant reefs and having dive sites to yourself.
We tailor make all itineraries and it’s possible to combine parts of the Banda Sea with Raja Ampat for those who prefer a longer cruising experience.

Alor and the Savu Sea

When researching scuba diving Indonesia, little is written about Alor in comparison to Bali, Komodo, Banda and Raja Ampat but it’s one of our favorite destinations.

Alor is a region for adventure, exploration and phenomenal scuba diving. The currents here are caused by water being forced between the main land masses of Alor, Ternate and Pantar. This constant flow of nutrient rich water results in spectacular coral reefs that are teeming with life and bursting with colour.

This off-the-beaten-path destination offers a mix of both world-class and wide-angle worthy reefs along with fascinating macro sites that are packed with critters. Pristine coral reefs, steep walls, sub-marine sea mounts, sloping muck sites – the diving in Alor is incredibly diverse. There’s no doubt that Alor will excite even the most discerning divers and underwater photographers.

For a longer cruise experience on board El Aleph, we can tailor make an itinerary that combines Alor and Komodo or the Banda Sea.

Komodo Marine Park

The Komodo Marine Park is not only a marine protected area, it is also a UNESCO World Heritage Site – and it’s beautifully positioned for scuba diving cruises.

Best known for its population of over 5,500 Komodo dragons, Komodo is a world class destination that features on many divers’ bucket lists when it comes to scuba diving Indonesia.

The islands that are in the park are rugged and wild – much like the diving. Think of thrilling drift dives with kaleidoscopic corals and an absolute mass of fish – that’s what awaits you in Komodo. Marine life comes in all shapes and sizes, from exquisite nudibranch through to reef sharks, manta rays and seasonal mola. For those who enjoy drift diving and currents, diving in Komodo is an exhilarating adventure that is rich in sea life from start to finish.

Some of Komodo’s most pristine reefs are not accessible by land-based operators and many liveaboards in the region follow the same well-known routes. El Aleph’s spirit of adventure and pioneering cruises ensure that you and your guests dive at the best sites – many of which are unknown to others.

Raja Ampat & Misool

Raja Ampat and the Misool region – including Misool Eco Resort’s no-take zone, are considered the jewel of scuba diving in Indonesia.

This is the chance to explore the ocean like nowhere else on earth. Marine biomass is beyond belief with fish densely packed into schools, manta rays performing underwater ballets, and corals that are competing for space on the reefs that are awash with colour.

Raja Ampat was created for sea exploration, the vast region has so much to offer that it simply makes sense to cruise the region to maximize your diving opportunities. Our experienced team know the Raja Ampat islands like the back of their hands, they know the best dive sites and they’ll take you to areas where other vessels haven’t ventured to before.

The stunning seascapes of Raja Ampat are breathtaking, and the region is well known for its migrating whale sightings, pods of dolphins, dugong, numerous species of shark (wobbegong, white tip, black tip, grey nurse, bamboo, epaulette and the list goes on). On the smaller end of the scale, you’ll see tiny pygmy seahorses, nudibranch, cowries, tiger shrimps, flying gurnards, Pegasus sea moths and so much more!
