TWIN ROCKS   Max Depth: 20m    Ave Depth : 12m. Located meters from the shores of the stunning Koh Nang Yuan Island, Twins is a dive site for everyone. A series of submerged rocks separated by narrow sand patches sees the depth increase from 6m in the shallow's to 20m at the deepest point. The highlights here are definitely the Clown Fish nests, the Lion Fish burrow, the Triggers and the safety stop Barracuda school. All against the background of colourful coral gardens and abundant reef fish makes this dive site underwater heaven.
