The best diving spots in Southeast Asia

Sipadan Malaysia diving

Sipadan Island, Malaysia

Sipadan Island is often hailed as one of the world's best dive sites – and for good reason too. Where else in the world can you witness a hypnotic barracuda vortex and swim inside a huge school of whirling jackfish? Sipadan is an oceanic island off the coast of Sabah, Malaysia, sits on top of an extinct undersea volcano and surrounded by almost 1,900ft deep canyons – all of which combined makes this spot a rich marine habitat.

Dive season All year round, best months from April to December

Difficulty level Mid to advanced, expect some strong currents and drifts dives

Raja Ampat diving

Raja Ampat, Indonesia

This stunning group of islands on the eastern-most point in Indonesia are often featured in ads by the Indonesian tourism board. The best way to marvel at the exceptional underwater landscape of never-ending colourful reef walls where hard and soft corals compete for space and swim among marine creatures of all shapes and sizes is to do a liveaboard and hop around the various dive sites. Famed for its biodiversity, spottings of wobbegong sharks, whitetip reef sharks, manta rays, batfish and large schools of tuna and mackerels are common.

Dive season All year around 

Difficulty level All levels, although some dive sites are not recommended for beginners or those not comfortable in currents

Similan diving

Similan Islands, Thailand

The nine granite islands lie about 100km north-west of Phuket and are part of a National Marine Park. The park only opens during dive season for the best chances of spotting manta rays and whale sharks. The sites on the East coast are generally easier with gentle sloping coral reefs while the West coast is slightly more challenging due to its giant granite boulders, fan corals and incredible submarine rock formations. There are also some dive sites for muck diving – so watch out for critters like ghost pipefish and sea moths. 

Dive season Late October to early May

Difficulty level Beginners to mid, plenty of easy dive sites with weak to moderate currents. 

Layang Layang diving

Layang Layang, Malaysia

A little closer to home and slightly more hidden is Layang Layang in Malaysia famed for its scalloped hammerhead sharks – the biggest drawcard in this area. If you're lucky, you might catch a glimpse of a school of them gliding by, making the trek out to this island entirely worth it. Manta rays often frequent this deep water area. Shore dives are possible although visibility is only around two to four metres near the pier. 

Dive season All year round, but higher chances of shark spotting during mating season in April to May 

Difficulty level All levels, about 12 dive sites in total

Tubbataha diving

Tubbataha Reef National Marine Park, Philippines

Declared a world heritage site by UNESCO in 1993, the Philippines' Tubbataha Reef National Marine Park is teeming with marine life – but to get there, you'll need to do a liveaboard making it one of the least crowded dive spots in the Philippines. Located in the middle of the Sulu sea and in the middle of the Coral Triangle, you can find sharks, hawksbill and green turtles and small reef fish congregating. 

Dive season March to early June

Difficulty level All levels

Banda Island diving

Banda Islands, Indonesia

Getting to Banda Islands in the Molucca region in eastern Indonesia is a pain. But once you get yourself there, you'll find its inaccessibility is a blessing because its reefs and marine life are as healthy and untouched as they come. Do a liveaboard to truly experience the diversity of the archipelago's 11 islands, of which seven is inhabited.

Dive season All year round, each season offers a different experience

Difficulty level All levels

Malapascua diving

Malapascua, Philippines

Divers come to Malapascua in Cebu, Philippines for one reason and one reason only – to observe thresher sharks in their natural habitat. This area is reputedly the of one of the only places in the world where the thresher shark can be seen within the limits of a recreational diver, although there's plenty of other fishes (so to speak) in the sea too. Macro diving is pretty popular too – seahorses, cuttlefish, pipefish are among those found on the seabed. 

Dive season All year round

Difficult level Mid to advanced
