Elephant Head (Hin Pusar)
Most divers and snorkellers regard this site as the best in the Similans. Located just south of Koh Similan, Elephant Head comprises a number of large boulders which create a sophisticated series of channels (some of which are swimthroughs). The site reaches a depth of 40 metres and currents get pretty strong. As such, beginners are not advised to dive here. An excellent dive site – plenty to see and a genuine diving challenge.
