This shallow collection of large underwater boulders and rocks occupies a plateau just off Koh Tao's western side. It's a great place to spot blue spotted stingrays, giant trigger fish, white-eyed moray eels and puffer fish. White Rock also doubles as an exceptional night dive with a fantastic array of critters and invertebrates showing off their colors. The highlight of the dive, however, are the large yellowtail barracuda hunting small reef fish in your torchlight.
