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.

Local Intel For Red Rock
Community notes to help plan your visit.
Scuba
Typically dived as a drop dive, with the group converging shallower toward the end for safety stops.

Not a freedive-first site; the swim-through and structure make it better for scuba than relaxed no-gas planning.
