Run by American Lisa, this simple yet inviting guesthouse with a small onsite dive centre is on tiny Kahaini Island, just offshore from Chea village. Guests are accommodated in a large wooden house with three simply laid-out and clean rooms. There's a rudimentary outside shower and 24-hour electricity.
Aim for the slightly dearer East Room, which has its own toilets. Food is fresh and tasty, and there's excellent swimming and snorkelling around the islet. Although Kahaini Guesthouse mainly targets divers, it will also appeal to nature lovers – the atmosphere is delightfully chilled-out. Boat transfers to Seghe airstrip (30 minutes) are S$500 for two people one way. Cash only.
