Foggy Shark Cave is a Central Coast boat dive built around a rocky cave where two reef faces meet. It sits on a larger north-south reef line and is known for reliable grey nurse shark encounters, overhead sections, sponge and gorgonian growth, and patient reef exploration when the swell is settled and the cave entrance is timed on slack water.
