Koh Tao, which translates to Turtle Island, is the northernmost and smallest of the 3 inhabited islands in the Samui Archipelago behind Koh Phangnan and Koh Samui. The south and west coasts of the island have white sandy beaches, and the north and east coasts have a couple of small sandy beaches but are predominantly made up of granite boulders.

The Diving around Koh Tao is amongst the best in The Gulf of Thailand, with enough variety to satisfy all levels of diver. There are sheltered, shallow bays which are ideal for students and beginners, and there are deeper sites ranging from submerged pinnacles to gentle sloping reefs. The sites have an abundance of hard and soft corals, an array of large pelagics and a rich diversity of marine life.
