The Similan national park is famous for its divesites. It has typically 2 different kind of diving. East side diving consists of gently sloping coral reefs with sandy patches and the occasional boulder in between. West side diving is known for its huge underwater granite boulders with numerous swimthroughs. Maybe the most famous east side dive site is East of Eden, off Island number 7.
