Koh tao scuba club



Location: Between Koh Tao and Koh Phangan

Depth: Average 18 m / Maximum 40 m

Level of Diving: Beginner to Experienced Divers


Sail Rock can be easily located in the Gulf as it is an impressive pinnacle that breaks the surface. A great way to begin the dive is to enter through the magnificent chimney at around 4 m that then presents an exit at a depth of 18 m. Keep your eyes peeled for an encounter with a giant green moray eel and clustering coral banded shrimp. An easy dive site to navigate by circling the rock formation, you may also come across pelagic fish such as whale sharks and bull sharks.







Location: About 5 km northwest of Nang Yuan

Depth: Average 20 m / Maximum 36 m

Level of Diving: Experienced Divers

Located approximately 8km from Koh Tao, this pinnacle takes up to an hour to reach, but is well worth the wait. Divers are typically greeted by great visibility which allows them to take in the truly colossal shoals of fish which populate this site, making it one of our all time favourites.

Heading South of the ridge, it is possible to leave the main pinnacle and strike out to Barracuda Rock, named for the huge shoals of Chevron Barracuda it attracts. Look out for enormous Marbled Grouper lying in the depths. The shallower areas near the top of Chumphon Pinnacle also harbour vast numbers of Magnificent Anemones complete with Pink Anemonefish and Damselfish.




Location: About 7 km Southwest of Koh Tao

Depth: Average 17 m / Maximum 28 m

Level of Diving: Beginner to Experienced Divers


A row of pinnacles offering wall dives and fantastic schooling marine life such as snapper, trevally, and barracuda. The shallower points are carpeted with gardens of sea anemones and the deeper gullies are filled with healthy gorgonians and whip corals.




Location: North-West of Koh Nang Yuan

Depth: Average 12 m / Maximum 30 m

Level of Diving: Beginner to Experienced Divers


A spectacular dive site offering adventurous swim-throughs provided by large archways, caverns, caves and crevices which cut through the submerged, bouldering rocks.

Home to the yellow margin triggerfish, divers may encounter a ‘trigger- attack’ during the spawning season, as they become very territorial and protective over their nests which makes for an interesting dive.




Location: North-East of Koh Nang Yuan

Depth: Average 12 m / Maximum 20 m

Level of Diving: Beginner to Experienced Divers


Nicknamed ‘Red Rock’ – a pinnacle that stems from 18 m to just below the surface shelters stingrays, turtles and scorpionfish in the crevices formed through erosion over decades. Taking a heading of 240 degrees, toward the coast of Nang Yuan, you may encounter the infamous titan triggerfish that lingers at the base of a cave opening. This narrow cavern may be explored at the depths of 12 m. Prior to entering be aware that training in cavern diving is necessary for this penetration.




Location: Western side of Koh Tao

Depth: Average 16 m / Maximum 28 m

Level of Diving: Beginner to Experienced Divers


White Rock is one of the most popular dive sites of Koh Tao for both day and night dives. It is home to the titan triggerfish, some of which occasionally act quite aggressively. The rock structures are a number of elevated shelves that provide shelter for honeycomb groupers, long-spined black sea urchins and various sea anemones, along with the soft coral mixed with knob and pore corals and the colourful Christmas tree worms. If you enjoy underwater photography then this dive site provides the composition and marine life for great pictures.





Location: East of Koh Nang Yuan

Depth: Average 6 m / Maximum 16 m

Level of Diving: Beginner to Experienced Divers


Located on the east side of Koh Nang Yuan, Japanese Gardens is separated by one of the world’s only sandbars connecting three teardrops of land. Fantastic snorkelling and great conditions for beginner divers, this dive site offers sandy bottoms to prepare initial divers adjusting their buoyancy prior to venturing to the reef areas. The reef dive itself is incredibly beautiful, home to many juvenile fish including blue-ringed angelfish, moon wrasse, damsel and Chromis fish with multiple porcupine pufferfish hiding within the crevices. On some occasions, you may spot the black and white banded sea snake.
