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 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. 

Mergui Archipelago
Remote Lands

Mergui Archipelago, Myanmar

Located in the north of the Thai border in the middle of the Andaman Sea is the Mergui Archipelago, a collection of over 800 stunning islands over 12,000 square kilometres. For years, a small group of intrepid divers have been coming from Thailand to this relatively isolated archipelago. The waters are home to diverse marine life such as manta rays, mobulas and a variety of shark species including grey reef, nurse, zebra, silvertip, and occasionally whale sharks.

Dive season October to May

Difficulty level Medium

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, green turtles and small reef fish congregating. 

Dive season March to early June

Difficulty level All levels

Komodo National Park

Komodo National Park

One of the best places in the world to dive is the Komodo National Park, a group of volcanic islands between Sumbawa and Flores. Besides being home to the elusive Komodo dragons, the national park also has a large marine ecosystem: with around 1,000 species of fish, ten species of dolphin, and five species of sea turtle. You can also see massive manta rays, white-tip and black-tip reef sharks, and hammerhead sharks – among others. Best suited for advanced divers, Komodo National Park offers exhilarating drift dives at several channels in between the many islands with swift currents.

A highlight is the Makassar Reef, a 2km channel with a unique seascape featuring craters and dunes of small rocks which have been shaped by currents. There are also sheltered dive sites boasting a myriad of critters hiding amongst slopes and walls of healthy hard and soft corals.

Dive season All year. The best diving conditions run from March to October, while you can see manta rays during the rainy season from December to February. Visibility is best from November to January.

Difficulty level Advanced. Komodo National Park has some of the strongest currents that can reach up to 8 knots.
