Situated 60 kilometers off the coast of Chumpon but falling under the jurisdiction of Surat Thani, Ko Tao lies 45 kilometers north of Koh Phang Nga and is only 20 square kilometers in area but it is known as the best diving site in the Gulf of Thailand.
The turquoise water of Koh Tao is crystalline, coconut plantations still cover much of the landscape, and concrete roads are built along only a few beaches. Getting around the island is either by pick-up taxi or by boat.
Motorbike and mountain bike are also available for rent to explore the island. Attractions in and around Koh Tao include Hat Cho Po Ro Ko Nang Yuan Kong Hin Khao Kong Hin Chumpon Ban Mae Hat Kong Sai Daeng.
