Castle Rock
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. The rock is around 200m in circumference, has many overhangs, walls and swimthroughs, and can be circled several times in a dive.
The fixed depth, lack of current and easy navigation make this the perfect dive for newer Open Water divers.
