The tiny island of Koh Tao ("Turtle Island"), 45 km north of Koh Phangan, is one of the top scuba diving destinations in Thailand. The shallow, crystal clear waters of Koh Tao feature abundant marine life and considerable coral that are certain to please both beginners and experienced divers, particularly as the island itself is so spectacular and the atmosphere on Koh Tao is relaxing.

Koh Tao has more than 20 dive sites. The best dive sites are Sail Rock, Chumphon pinnacle, Southwest pinnacles and Shark Island. You have a big change to see Hawksbill- and Green sea turtles, Titan- and Yellowmargin triggerfishes, Blue spotted stingrays, baraccudas, massive groupers and loads of jacks, snappers and fusiliers. When you visit Koh Tao in the months April and May you have a chance to see Whale Sharks.
