Located about 100 metres from another great dive site, "The Gap", the pair of them make a great double dive. Blue Grouper, Abalone, Crayfish, Blue Devils, Wobbegongs, Nannagui, and other fish life abound. The cave has a sandy bottom, and the walls are covered in sponges, gorgonia's, and other soft corals.
