My wife and I rented a longtail boat and were traveling around the island when we found Rocky Bay. The bay has aqua marine water. Crystal Clear. The Raft restaurant is only about 500 metres from shore. We chose our lunch by borrowing snorkeling masks from the Raft and swimming under where there are live fish in large cages accessable from a trap door in the floor of the raft. The fish was excellent and after we went for a swim near the beautiful beach. A must to see if you are visiting Ko Tao.
