Ko Taen is located at Mu 2, Tambon Taling Ngam, to the south of Ko Samui. It is a beautiful island of tranquil nature. Its long beach is fringed with coconut trees. To the east, a long beach parallel to inshore coral reefs is called Ao Ok. To the west, it is a closed bay with a strip of mangrove and a rocky beach, called Ao Tok. Here, the shore and coral reefs are rather unspoiled. One interesting thing of this island is that no dog lives here. There were many theories supposed to explain this matter: the sacredness of the island, or scientific reasons; such as, sound waves, magnetic fields etc. Apart from the abundance of the forest and nature, Ko Taen also boasts four routes of a nature study trail. Each of the routes offers a different natural landscape as well as living conditions of the villagers of Ko Taen. On the first three routes, in particular, visitors will see various birds inhabiting the island. It is recommended that visitors bring their binoculars, cameras, and notebooks for keeping memories and impressions of bird-watching. The fourth route is a marine one in which visitors will admire the beauty of the underwater world as well as the coast of the island.
