About Shark Island
Shark Island is a southeast Koh Tao boat dive on a small granite islet with two distinct reef personalities. The east side carries soft corals, sea fans, and sponge-covered ledges, while the west side turns into harder coral and denser reef structure. It suits intermediate scuba teams looking for a varied route with current-sensitive conditions and regular rays, moray eels, barracuda, turtles, and reef fish.
