I found 3 points on the map: Ao San Beach - Great beach to swim with a mask and fins. A lot of marine life. The beach is small and, recently, has become quite famous, so it is crowded. There is a restaurant and rental of swimming accessories. Drive to this beach through a hotel at the right end of Nai Harn Beach. Yanui Beach - The southernmost of the island's swimable beaches. A small but very pretty beach under the mountain by the windmill. There are several cafes across the street from the beach. Great place to swim with a mask and fins. Siam Beach - Great place for snorkeling. Lots of starfish and colored fish + rock Access to the beach through the Sabai Corner Hotel. Entrance 50 baht.
