Hin Lak Ngam
A rock that just breaks the surface beside Ko Ngam Noi in the Mu Ko Chumphon islands, close to the HTMS Prab wreck. Local sources describe a 5–20 m dive with one of the thickest stands of black coral in Thailand, red sea whips and large anemone colonies; a diver report mentions two huge leaning boulders forming a coral-filled passage. Triggerfish, pufferfish and nudibranchs are among the common sightings.
