White Rock
White Rock lies between Sairee and Koh Nang Yuan and is one of the largest and most varied sites around Koh Tao. Granite boulders, sandy channels and coral patches run from about 5 m to 22 m, with a big mass of red fan coral in the middle. Turtles are seen regularly, giant groupers hover by the rocks and great barracuda hunt as the light fades. At night it is one of the island's best dives, with sleeping parrotfish and hunting morays.
