Description
The English to Thai translation of Koh Tao is “Turtle Island”. It was originally named by local fisherman and settlers who described a turtle shape when looking at the island from their boats. The island does have a healthy population of sea turtles with both Hawksbill and Green turtles living in the waters off the island. They are a common sight for divers when they are out fun diving or taking a diving course.
Koh Tao is known for beeing one of the best places to learn to dive, and yet see beautiful coral reefs with plenty of fishes

Information about the site
Green Rock offers several small swimthroughs, caves and crevices where marine life can be seen sheltering. The boulders range in depth from 5 metres down to around 32. There is often a strong current here that you can use to drift around the submerged pinnacles so its not really recommended for inexperienced divers. You will certainly encounter Yellow Margin and Titan Trigger fish here as it forms a popular breeding ground for them ... so approach with caution
