Sail Rock

Sail Rock is a pinnacle that juts from a depth of 45 metres to the surface; it's approximately halfway between Koh Tao and Koh Phangan. As one of the Gulf of Thailand's top dive sites, it's a great place to visit. If you are an advanced open water diver or above it is the perfect dive to practice your deep diving skills.

You will start above the thermocline; tuna, king mackerel and jacks circle just off the pinnacle, be sure to look for the white-eye and yellow-edged morays lurking in cracks in the jagged rock. Octopuses and scorpionfish seem to magically blend in with the colourful soft and hard corals so you'll have to be sharp eyed to spot them. There is a rock 'chimney' where you can enter an opening, which has an amazing vertical swim-through that ascends 10 meters from a depth of 18 metres. Rise up slowly enough to enjoy the patterns of light and shadow and frequent windows into the blue open ocean that portal the walls of this natural rock tunnel. You will emerge into thick schools of jacks, snappers and trevalies.

At the top of the site you will finish with a bright ring garden of anemones and coral. This is a great spot for pelagics, such as kingfish, mackerel and due to its location and depth; this is also a likely site for whale shark and manta sightings.

You're most likely to see either Hawksbill turtles or Greenback turtles around Koh Tao, though other breeds occasionally stop by.  This particular Hawksbill is a resident of these parts and is regularly seen at the Twin Peaks dive site feeding on corals.
After the exhileration of the dives, chill out in the hot sun on the deck of one of Master Divers' dive boats.
