Ao Nai Wok, is the long bay that extends north from Thong Sala after the main pier. At the top end, walking distance from town yet far enough away to never to notice it, a number of resorts populate the beach and rocks start to break up the coastline. The bay is fairly shallow, thus swimming is best in high tidal season (November to April).

There is a reef about 80 metres out where the sea shelf drops allowing for some reasonable snorkeling conditions.
