Top Dive Sites - Gulf of Thailand

Gulf of Thailand Dive MapThe Gulf of Thailand offers divers lots of diversity. The beautiful island of Koh Tao, along with the pristine islands of Koh Samui and Koh Phangan, are part of the itinerary. Located in the north of the gulf region there are many unspoiled areas with reefs full of hard coral, and soft corals and lots of fish.   Whale sharks are frequent visitors to Koh Tao. Nearly all of the 9 islands are surrounded by huge underwater rock formations, eroded by the action of a relentless sea. These stone giants are home to an amazing variety of marine life.  Narrow swim-throughs, caverns and underwater canyons form a truly unique diving landscape.

Ao Leuk - The Thai name means 'Deep Bay' which is one of the shallowest of Koh Tao's dive sites, with its sandy bottom allowing a maximum depth of about 40 feet.  There are lots of reef fish such as butterflyfish, angelfish, schools of juvenile yellowtail barracuda and turtles.

Chumphon Pinnacle is Koh Tao's best and most famous diving spot and it should definitely be part of your east coast Thailand diving itinerary. The spot features several pinnacles and underwater boulders with great marine life such as batfishes, barracudas, potato groupers, leopard sharks, bull sharks and all the usual reef fishes of the gulf of Thailand. It's a granite pinnacle to the north west of the island and which starts at about 40 feet under the surface and goes down to a maximum depth of 100 feet. There is one main pinnacle which is surrounded by a dozen or so smaller rocks in the deeper areas. 

Hin Wong Pinnacle - This is a unique dive at Koh Tao Island. The large granite pinnacle is at the northern end of Hin Wong Bay. The north side is beautiful with purple soft corals and many different kinds of sea fans, whip corals and black corals. Blue and black damsels swarm around you as if in greeting as you enter the water. Down on the bottom you might see small groups of shrimpfish driftby.

Koh Nang Yuan - The small islet of Nang Yuan is connected to Koh Tao by a thin strip of white sand and is surrounded by several charming dive sites. It's an area for relaxed and easy scuba diving and is also a very popular place for snorkelling as there are plenty of reef fish.

Shark Island - is a small rocky islet off the southeast coast of Koh Tao. The eastern side is the more interesting with its boulder formations. Many types of tropical fish are found around here. On the south side at 14 metres is a soft coral garden on a rocky bed. You'll see leopard sharks and turtles.

Southwest Pinnacle is approximately 13 km south west from Koh Tao and in many ways it is like a shallower version of Chumphon Pinnacle.

White Rock - The site is located mid distance between Koh Tao's Mae Haad Pier and Koh Nang Yuan. The site consists of 2 large boulders which are only  10 feet apart. These big stones are surrounded by smaller boulders and patches of coral. Trevor the Triggerfish is the star of the show at this dive site as he is the most aggressive triggerfish at Koh Tao.

Laem Thian -  is located on the East side of Koh Tao Island. It is an easy and relaxing site where the topography is interesting with small caves and swim-throughs. It is here where you may see turtles, a blue spotted stingrays, groups and schools of jacks.
