Dive Sites

Shark IslandPossibly Koh Tao's most varied site, Shark Island is a small uninhabited island just to the southeast of Koh Tao. Sloping gently from the surface down to 24m, there is always something new to see here including some of the Gulf of Thailand's most stunning soft coral.
White eyed moray eels, blue spotted fantail rays, porcupine and puffer fish, and an enormous variety of reef fish are almost guaranteed in the beautiful shallow coral garden, while the fortunate may also see whale sharks, leopard sharks, reef sharks and other pelagics on the deeper side.

Titan triggerfish add an element of excitement to each dive, and divers often spot turtles and sea snakes.

SailrockA single rock that protrudes from the water between Koh Tao and Koh Phangan, Big Blue in Koh Tao visits Sail Rock less often than the other sites, but the dive is well worth the trip. The most noticeable feature of the dive is "the chimney" - a vertical tunnel in the rock that leads you from 18m to 8m, but the entire site (from the surface to 45m) is full of points of interest. The rock is riddled with small holes which makes a perfect habitat for white eyed and yellow margin moray eels, and the large anemones that cover it are filled with anemone fish and shrimp.

Whale sharks can be seen in the winter months here as well, and keep an eye out for other large pelagics. Octopus camouflage themselves so exactly to match the covering of the rock that you may miss them completely, but keep your eyes peeled - they are there.

chumponWidely considered Koh Tao's premier dive site, Chumphon Pinnacle is also one of the island's most challenging with occasionally strong currents.Ranging from depths of 12m to 40m, the site is a group of massive rocks arranged in a rough oval and running north to south.

Visibility is superb in season, and the site plays host to a wide variety of pelagics as well as reef fish. Great barracuda, king mackerel, grouper, and tuna throng to Chumphon all year around, and in season whale shark sightings are common. As the site is a fair distance offshore, visitors from the open ocean are unpredictable -sailfish, oceanic white tip sharks and bull sharks have also been spotted.

SW2Southwest Pinnacle, a series of rock formations ranging from 4m to 30m and is another of Koh Tao's top ten. The tops of the pinnacles are covered with a carpet of anemones in brilliant greens, pinks and blues, with their cavalcade of pink anemone fish. Leopard sharks and whale sharks are occasional visitors to the site, which is home to large schools of snapper, yellowtail barracuda, as well as fusiliers.

Large groupers can be seen here as well, along with scribbled filefish and masked porcupine fish. The observant diver may spot scorpion fish and stonefish camouflaged on the rocks.
