Above water this formidable rocky karst conjures up all sorts of images of what to expect in the depths below.

This is primarily a wall dive, although there are scattered rocks worth exploring away from the wall itself, frequented by more than a few large Black and Whitetip Sharks.

The wall itself features small green branch corals, with lots of holes and crags forming protective lairs for crayfish and other small invertebrate. Solitary juvenile Blue ring and Emporer angelfish can be seen fluttering around.

There can be a lot of wave action here and the roar of the water crashing into the caverns and caves above the surface echoes around the site.
