About this site

Koh Bon Pinnacle sits off Koh Bon, a small island in the Andaman Sea within Mu Koh Similan National Park, Phang Nga province, reached by liveaboard or long boat trips from the mainland or the Similan Islands. The pinnacle rises from deeper water some distance west of the island's main ridge, separate from the more commonly dived Koh Bon Ridge closer to shore. It reaches a maximum depth of around 50 metres over a rocky bottom and is rated an advanced dive, with the depth itself flagged as a hazard and some sources also noting a lack of buoy line marking and strong currents. Leopard and zebra sharks, manta rays, trevally, and whale sharks are regularly seen here, and divers have also reported barracuda, batfish, clownfish, grouper, guitarfish, nurse sharks, and tuna around the pinnacle.
