About Turtle Rock
Turtle Rock is a granite reef on the west side of Similan Island 8, named for the turtle-shaped boulder that marks the site. The dive mixes sheltered boulders, coral growth, and swim-through terrain with regular turtle sightings and active reef life, making it a classic Similan boat dive and a favorite night dive when the bay is calm.
