The best beach on the island, Bai Dat Doc is a simply beautiful cove, consisting of a kilometre-long crescent of pale sand, backed by green hills. It has a gently shelving profile and no pollution, so it's ideal for swimming. Though it's backed by the luxury bungalows of the Six Senses hotel, it's not a private beach and there are access points close to the road.
Very rarely dugongs have been seen frolicking in the water off the nearby cape.
