Aow Leuk

Depth 2m-12m

This shallow dive site is great for student divers to practice their skills. A good option for fun divers is to get dropped off at Hin Ngam (on the way into Aow Leuk) as it offers a wider variety of marine life and is also a little bit deeper.

Chumphon Pinnacle

Depth 14m-35m

Regarded as one of Koh Tao’s best dive sites when conditions are good, Chumphon Pinnacle is located within a 40-minute boat journey away from the island. This is a dive site you must visit during your stay on Koh Tao. You can see many huge shoals of fish, and this is where you have the best chance of seeing a Whale Shark. Check Twitter @roctopus for sightings.

Green Rock

Depth 12m-20m

Green Rock is a great dive site to explore. It offers many ‘swim throughs’, great corals, and enough marine life to make you come back for more.

Hin Wong Pinnacle

Depth 10m-28m

This dive site is a good alternative to Chumphon Pinnacle as it’s usually quiet. Located on the East side of the island it’s made up of many large boulders, so there are plenty of places for the fish to hide.

Japanese Gardens

Japanese Gardens is a popular dive site and another good choice for beginner divers. Located around Koh Nang Yuan, it contains many different varieties of hard corals and resembles a garden – hence the name.

Mango Bay

Depth 2m-12m

This beautiful secluded bay offers some good shallow water diving. You can explore both sides of the bay or do a ‘drop off’ on your way into it (preferred by fun divers)

Red Rock

Just around the island from Japanese Gardens, Red Rock is a small pinnacle that comes up to just below the surface of the water. If you go to Red Rock, you need to swim to the coast and find Nang Yuan Cave. It’s one of the more beautiful swim-throughs on Koh Tao and should not be missed.

Sail Rock

Depth Surface-40m

This is the best dive site in the Gulf of Thailand. A very impressive place that attracts a huge amount of marine life. This site is not visited every week as it’s a 2 hours boat journey to get there. Send us a message to find out when the next trip is.

Shark Island

Another ‘must see’ dive site during your visit to Koh Tao. At Shark Island, you don’t see any sharks (it got its name due to the shape of the island looking like a shark fin) but you will see everything else you could possibly want to see on Koh Tao.

Southwest Pinnacle

Depth 5m-28m

This dive site is very similar to Chumphon Pinnacle. It consists of one main pinnacle which is surrounded by smaller pinnacles. See if you can find the ‘secret pinnacle’.


Depth 10m-18m

Twins is the most popular dive site on the island. It’s small, quite shallow, and offers a big selection of fish life and corals. You should also explore Buoyancy World (located to the north) which is a group of sculptures and buoyancy aids… definitely something you don’t see very often underwater!

White Rock

Depth 10m-20m

Another popular choice. White Rock is one of the biggest dive site around Koh Tao and will need more than one dive to truly explore.
