Koh Bon information
Koh Bon is remote uninhabited island which recently added to the Similan islands National Park . It’s located 20 kilometer north of Similan Island No 9. The island has no beaches and is in the shape of a horseshoe. Both above and below the surface the waves surge through holes that they have cut right through the island. The breathtaking scuba dive underwater terrain on the southwestern point has a step-down ridge that carries on to depths of over 45m. The western side of the ridge is more of a gentle slope with coral bommies forming mushroom-like formations out of the finger corals. On the ridge itself, seafans of different sizes, shapes and colors grow, and schooling fish swim in the current feeding. This perfect feeding ground for manta rays, gives you your best chance of seeing and diving with them in the whole of the Andaman Sea.
