Castle Rock is located outside the Port Phillip Heads in approximately 18 metres of water. It sits on a sandy bottom and rises to around 12 metres at its pinnacle. The rock is around 200metres in circumference and has many overhangs, walls and swim throughs. It can be circled several times in a dive. The fixed depth, lack of current and easy navigation makes this the perfect dive for new Open Water divers. It is a wonderful fish dive, with a wide variety of creatures from Sea Dragons to Port Jackson Sharks found on and around the Rock. There is even a slim chance of a Cray or two under the overhangs at the bottom. This is an awesome night dive site.
