Ko Rawi has limestone hills and dense jungle, with first-rate beaches and large coral reefs offshore. Wild camping is allowed, with permission from the national park authorities. Excellent snorkelling spots include the northern side of Ko Yang and tiny Ko Hin Ngam, which is known for its unique stripy pebbles. Legend has it that the stones are cursed and anyone who takes any away will experience bad luck until the stones are returned to their source.
