Koh Bon Island is located 20km/12mi north of Island 9 in the Similan Islands and is famous as a ‘zoo’ for manta rays. It is a popular dive site, known for a diverse marine life. The dive site has multiple areas, with several zones of interest to divers: the ridge that goes down to more than 45m/148ft deep, the two pinnacles, and a small cove. The main area out of these is the ridge, the eastern side of which is the entrance to the site. The western side is one of the reasons divers come here--it is covered with an elegant garden of variously shaped and hued corals and sea fans, with an abundance of fish swimming through their branches. Due to the considerable depth and the currents of notable strength that can sometimes occur, for safety reasons this site is only recommended for advanced divers.
