Racha Noi Bay is a dive site located on the east side of the South Island of Racha Noi. Going offshore from the beach, there is a large root with megaliths folded on top of each other, separating the area from north to south around it. The depth is about 25M to 10M, and small roots are scattered in the shallow water on the sandy ground. The main point is the megalithic area, with a long slot on the south side.
