About This Site

Dive at Koh Bon The small uninhabited rock island made of lava rock north of the Similan Islands is famous for its manta ray encounters. A fringed reef encases this beachless, bizarre rock in the Andaman Sea. A beautiful steep wall drops to 35 meters.Like planes, they come flying out of the deep blue waters and then turn off just before the diver. Reef sharks and leopard sharks complete the picture. Diving with Koh Bon manta rays is a must for every diver!
