Big Blue Diving

Dive into tranquility at this site boasting calm waters, perfect for diving. Just 30 meters offshore lies a vibrant coral reef, inviting diversto explore its colorful depths.

Rainbow reef is a shallow training area in the southern part of Sairee Beach. Up to 6m depth, this is the perfect area to try scuba diving for the first time with a local center.

Junkyard ranges from 10 to 12m in depth. It contains a lot of artificial items such as a Jeep and a toilet seat, all of which are new marine life habitats, so please don’t touch!

The range of life found here is huge and there is something to please every diver. Turtles come here to munch away on soft corals, casting a lazy, half-interested eye at divers. Koh Tao's infamous Titan Triggerfish prowl this dive site too, and some of the largest specimens hang out here. White Rock attracts many hunters: Great Barracuda and Trevally excite the fish making them dart for cover in the plentiful hard corals; Banded Sea Snakes wind their way through the corals searching for their prey. Blue-Ringed and Six-Banded Angelfish swim around in their buddy teams passing Beaked Coralfish, Bannerfish and Pig-Faced Butterflyfish. Look under ledges and outcroppings and you are bound to find a White-Eyed Moray Eel or a Blue-Spotted Ray awaiting nightfall. Under the South buoyline, a large shoal of Yellowtail Barracuda spend their days following divers. Even though White Rock is close to Koh Tao, in season Whalesharks are regularly seen here.

Large rock formations and smaller pinnacles (shallowest point is about 7m). Lots of soft corals and whip corals. Gets to 22m+. Not a lot to see if limited to 12m. Next HTMS Sattakut wreck and can both be dived in the same dive.

Bio Rock is an artificial reef with weak electrical currents flowing through its conduits to promote the growth of coral seedlings. Located off the coast of Koh Tao, opposite the Japanese Garden, this unique dive site is something truly special that Koh Tao has to offer.
