Koh Libong, Trang Province, Thailand

While many popular beaches in Thailand have been trashed by tourism, Trang Province officials are committed to sustainability and ecotourism. Koh Libong is the province's largest island and has been protected with the help of Swedish environmentalists. The sparsely populated area doesn’t get many tourists, leaving the golden beaches open to crabs, birds, turtles and dugongs.
