Hin Lak Ngam is a compact rocky dive site off Koh Ngam Noi where a marker rock breaks the surface and the reef slopes away through boulders, black coral growth, anemone patches, and reef structure that attracts hunting fish and passing pelagics. It is usually dived as an easy boat site around the visible pinnacle, with enough relief and marine life to keep both new and experienced divers interested.
