This “drift“ dive site is located on the north side of Nan Yuan Island, adjacent to Koh Tao. The name “Green Rock“ comes from the fact that the roots near the surface of the water look green. The depth ranges between 10 and 25 meters and 30 to 40 meters depth can be found with a short swim to the West.
Titan Triggerfish, White-eyed Moray Eel are quite common. This dive site is also recommended for divers who want to observe and take pictures of macro life like nudibranchs.
