Hin Chalam
Offshore rock south of the Samae San islands with a wall from about 4 m to 14 m, dived down to 22–25 m. Sea whips, gorgonians, barrel sponges, hard corals and anemones cover it; blacktip and bamboo sharks, morays, barracuda and nudibranchs are reported, and whale sharks and large eagle rays occasionally pass. The Royal Thai Navy and Air Force use the area for bombing practice and unexploded ordnance lies around the site.
