Koh Tao means "Turtle Island" in Thai, as this was once an important breeding ground for sea turtles, which have been reintroduced to the island's ecosystem in 2004. Koh Tao is worldwide famous for its beautiful coral reef and marine life which make it a popular place for snorkelling and scuba diving. Hikers might want to try and reach John-Suwan Viewpoint or Mango Viewpoint.
