About Koh Bon Pinnacle
Koh Bon Pinnacle is a remote, boat-accessed limestone pinnacle in the Similan season, known for bright soft coral, steep rock, and clear-water pelagic encounters. It suits experienced divers who are comfortable with drop-ins, tight buoyancy control, and short, current-aware profiles. When conditions line up, the site feels compact but dramatic, with plenty of blue-water space and a real chance of large animal fly-bys.
