Positioned between the South China Sea, the Pacific Ocean and the Indian Ocean, Indonesia is at the epicentre of marineDiver in shoal Tulamben_ Courtesy Minni Vangsgaard biodiversity. Although the world’s largest archipelago is comprised of more than 17,000 islands, most of the country’s 235 million people, live on just five - Sumatra, Kalimantan, Java, Sulawesi and Irian Jaya.

With more than 54,000 kilometres/34,000 miles of coastline you might expect diving in Indonesia to be outstanding and you won’t be disappointed.  The area has exhilarating drift diving, extensive reef diving, fantastic night diving, unique muck diving and breathtaking steep walls. Tec diving addicts can get their fix from the deep trenches while wreck fanatics will be satiated with the abundance of World War II relics. The country is also a paradise for underwater photographers as more than 600 species of coral and over 3000 fish species make their homes on Indonesian reefs.

Still one of the few places left in the diving world to be truly discovered - Indonesia surely promises something for everyone.



With one of the earth’s richest marine environments, Indonesia has hundreds of stunning dive sites that cater to divers of all levels. Here are a few of the most popular sites:


In total, North Sulawesi offers over 150 dive sites and is suitable for all levels of experience.

Considered one of the world’s top dive destinations, the Bunaken Marine Park covers a total surface area of 89,065 hectares/220,000 acres and boasts clear water, steep walls and world-class coral gardens that are readily accessible to both snorkelers and divers. You will encounter large schools of fish – along with spinner dolphins and pilot whales - that frequently visit the area. If you’re lucky, you’ll even spot a killer whale. But, aside from the big animals, you can spot some of the other 2000 species in the area – including seahorses, scorpionfish, octopi, sea fans, sponges, whip corals, hard corals and nudibranchs.

Manado – with its own airport - is the base for divers in this region. Just off the coast, dive areas include Manado Tua, Siladen, Mantehage and Nain islands. Near Molas Beach, just outside Manado on the mainland coast, you’ll find the wreck of  the Molas. This Dutch freighter sank during the second World War and its hull has become home for many fish species.

You can also visit the Lembeh Strait and see why the region is renowned for the discovery of new marine species.


Komodo Island lies directly south of Sulawesi between the neighboring islands of Sumbawa and Flores. Komodo National Park is legendary for its dragons - the world’s largest living lizard – but it’s the ocean that draws divers here. With strong currents, Komodo is best for intermediate to advanced divers. But, those strong currents also spread nutrients throughout the surrounding waters and sustain a remarkably vivid abundance of marine life. Dive Komodo and you’ll likely see a multitude of fish and some larger pelagics (mantas, dolphins and sharks) mammals. Take a liveaboard dive boat and you’ll get to see just about every type of tropical diving.


Just off of Lombok are the three Gili Islands - Trawangan, Meno and Air. These small, casual islands are gems that boast white, sandy beaches and excellent snorkeling and diving. Check out some of the 16 dive sites and you’ll be spoiled for choice – drift, deep, reef, night, photography, wreck and muck diving are all on offer. Whether you’re looking for shore diving or boat diving, a beginner or a hardcore diver, the Gilis have something for you. Just make sure that you are properly trained for the site you choose, as currents can be quite strong and drift diving is the norm along the walls, ridges, canyons and slopes.

During your adventure you can come across cuttlefish, octopus, lionfish and scorpion fish. If your trip coincides with a full moon, you’ll also get to see the school of huge bump head parrot fish that visit the area. Others critters include a variety of rays, sea snakes, reef sharks, moray eels, the occasional whale shark, masses of turtles (both green and hawksbill) – along with an immeasurable variety of hard and soft corals.

The Gili are also a great place to learn to dive or continue your education. You can choose from the many PADI Dive Centers and Resorts that cater to divers of every level.

The environment is also cared for as the Gili Eco Trust collects contributions from visiting divers and snorkellers (40,000 IDR for divers and 20,000 IDR for snorkellers) to fund special projects such as beach cleanups, recycling initiatives and reef conservation activities.

Many dive operators also offer expeditions in the Lombok Strait between Bali and Lombok. In addition there are dive opportunities southwest of Lombok that combine interesting adventures. For visitors to Senggigi who wish to take a dive, Malibu and Alang Alang Wall are idyllic spots.
