Diving in Biaha is divided up between the slightly more protected south west end, almost inside the crescent, and the more turbulent conditions on the north side. Just about the entire island is surrounded by a rich and dense coral reef, part rugged, black wall and part slope. On the inside crescent is a small cave where sleeping White-tip reef sharks are often spotted. Other marine life commonly seen here include leaf scorpion-fish, cuttlefish, angler fish and a variety of nudibranches that will satisfy any enthusiast. It is really more the landscape and the wild beauty of the site that makes it so spectacular for divers and keeps them coming back to this site every year.
