Caves and Canyons, located on Hook Reef in the Great Barrier Reef, is a 60m wall with a 20m shelf. This shelf is dotted with scores of bommies which are yet to be discovered and mapped. A great exploration dive as you never know what may cruise on by. Beautiful coral gardens with exceptional overhangs providing photographers with fantastic gorgonian fan opportunities. Keep watch for mackerel, tuna and Indian Steephead Parrot fish. Also, whales have been seen at this site!
