Red Rock
About Red Rock
Red Rock is a large pinnacle dive site located northeast of Koh Nanguan. The formation tops out around 20 m and is often used as a drop-dive start point, with divers moving shallower toward the end of the dive for their safety stops. Marine life includes classic tropical reef fish, with occasional large grouper seen inside a swim-through. Yellow boxfish, blue-spotted ribbontail rays, and the occasional turtle are also reported.
