Koh Samui has been a backpacker's destination since the late 1970s. Today, tourists from the whole world go to this easygoing paradise. It is located in the Gulf of Siam and surrounded by more than sixty other islands, some small and inhabited, some bigger (ex: Koh Phangan, Koh Tao (divers island), Koh Nang Yuan and Ang Tong Islands, the National marine park).
