About Koh San Chalarm เกาะสันฉลาม
Remote rock dive in southern Samaesarn, reached by boat and managed as a guided site because it sits in a navy practice area. The terrain is a small exposed rock with hard coral growth, pockets of rubble, and fish life moving around the edges. Barracuda, butterflyfish, scorpionfish, nudibranchs, and schooling fish are the draw, with military debris caution throughout and conditions that can change quickly from one side of the rock to the other.
