Best Scuba Diving Sites in ThailandHow do these rankings work?

1. Similan Islands

The Similan Islands are well known as one of the best places for scuba diving in Thailand. The best way to dive in The Similan Islands is from a liveaboard boat; most trips leave from Khao Lak, but there are departures from Ranong and Phuket too. You’ll see manta rays and whale sharks as you explore around the nine islands.

2. Koh Lanta

Diving here is by boat only, and you take either a speed boat or slow boat. The real diving jewel here is Koh Haa: five big rocks offer divers several caverns and swim-throughs. The amazing caves have wide entrance openings and ancient rock stalactite formations hanging down from the ceilings.

3. Sail Rock

This 30 metre submerged rock pinnacle off the coast of Koh Phangan is often regarded as the best dive site in the Gulf of Thailand and one of the best sites for whale shark sightings. It’s a magnet for fish and the waters are amazingly clear.

4. Koh Chang

There’s plenty of diving sites here, but the most famous is HTMS Chang. It is Thailand’s longest wreck at 117 metres and sits at 30 metres underwater. After more than 50 years’ service in the Royal Thai Navy, it was sunk in 2012 to create an artificial reef. It’s a great site to explore the cabins, briefing rooms and the main holding area.

5. Andaman Sea

This vivid spot has endless amounts of coral reefs and marine life. The Andaman Sea is home to plenty of vibrantly colourful creatures. Often, divers will see hawksbill turtles, leopard sharks and blacktip reef sharks.

6. Koh Tachai

This submerged ridge is made up of hard corals and boulders, which have formed numerous channels that you can swim through. You’ll see vibrant corals, large sea fans and reef fish but the main draw here are manta rays, whale sharks, groups of hunting tuna, schooling barracuda, leopard sharks, nurse sharks and hawksbill turtles.

This is definitely a top dive site for all big fish fans.
