Ko Adang's white sandy beaches, away from the buzz of Ko Lipe's long-tails, are a 10-minute boat ride (100B) from Hat Sunrise on Ko Lipe.
There are a few short jungle trails on Ko Adang that lead to small waterfalls. Great views can be had from Chado Cliff, a 30-minute hike above the main beach. Ko Rawi has a few trails too.
There's fine snorkelling off both Ko Adang and Ko Rawi. Top spots include Ko Yang, 1km south of Ko Rawi's southeastern end, and tiny Ko Hin Ngam, 3km further south, which has underwater fields of giant clams, vibrant anemones and striped pebble beaches.
