Samaesan Hole
Technical depth only: a sandy-bottomed depression between Koh Rong Nang and Koh Samaesan, about 85–100 m deep and the deepest recorded dive site in the Gulf of Thailand. It lies in an area marked on charts as an explosives dumping ground, under a commercial shipping lane, with strong tidal currents, poor visibility and no natural light below about 50 m. The first recorded descent to the bottom was in 1998.
Tiefe: 85–100 m
