Surrounded by rocks, Ao Thianok, a small beach, enables swimmers to explore the underwater coral reefs, the realm of small harmless sharks. After your aquatic efforts, why not sip a green coconut water on the terrace of one of the viewpoint restaurants. Beyond, a track continues to Eagle View, a small bar-restaurant built on a hill. You are most likely to see whale sharks out at sea from March to May and then again in September and October.
