Ko Phra Thong is the middle link in a chain of three islands. It is largely flat with expanses of inland savanna. It has long uninhabited beaches, fringed by coconut palms. There have always been a number of special natural features of Ko Phra Thong Island. It fronts onto over eight kilometres of beach on the Andaman Sea and, in addition, over six kilometres of beach on a beautiful bay containing small picturesque islands with rocks and coral for snorkelling. It is only 60 km from the Surin Islands, Richelieu Rock, and only slightly further to the Similan Islands. All are renowned diving locations.
