About Red Rock
Red Rock is a boat-access Koh Tao pinnacle made of a dramatic granite rock that rises almost to the surface beside Koh Nang Yuan. Divers use the swim-through cave and the shallow finish toward Japanese Gardens for a controlled route that suits careful buoyancy, photo pauses, and a good look at the reef life living on the rock and in the sand around it.
