Koh Nang Yuan Dive Sites

Around Koh Nang Yuan and over on the east side of Koh Tao there are several dive sites that consist of huge granite boulders that have fallen on top of each other over thousands of years.

This unique underwater topography has created small caves and Natural swim throughs that make the dive more interesting and provide shelter for lots of marine life.

With a well-established diving industry and local marine conservation community, Koh Tao has worked together on several established Artificial dive sites with ongoing projects.
