About this site

Red Rock (Hing Dang) is a pinnacle and boulder site off Koh Tao, Thailand, at 10 to 18 metres (33 to 59 feet), and it suits all levels.

The pinnacle holds pufferfish and boxfish in its cracks and crevices. Across towards the coast is one of the island's best swim-throughs, with huge archways between large boulders where sunlight breaks through. Glassfish, blue-spotted stingray, sweetlips and the occasional turtle show up there.

Along the coastline the boulders are covered in hard and soft coral, and bannerfish, angelfish and triggerfish live there. The sandy patches hold gobies and shrimp, and with a keen eye you may find scorpionfish.
