Turtle Cavern is one of the highlights of Sipadan island thanks to its incredible geological formations and turtle skeletons. About 18m deep is the entrance to Turtle Cave. The cave first goes down in a bell shaped descent tunnel and leads to the lower chamber. Following the left side of the cavern will bring you in front of a tunnel. This tunnel is connecting Turtle Cavern with Turtle Tomb a small cave system which contains many turtle skeletons. This is due to the great number of turtles that they simply enter the cave and are unable to find the exit. This dive needs an experienced guide and special equipment.
Depth: 14-23 metres
