Koh Tao which literally means Turtle Island, is an island in the Gulf of Thailand, and is a great place for divers who want to escape from places like Koh Samui, because it is a bit quieter, perhaps because it isnt very easy to reach, in fact your only option is by boat.

From the south it will take about three hours by ferry from Surat Thani on the mainland, one and a half hours from Koh Samui, and around an hour from Ko Pha Ngan.
