Hanging Rock is an offshore Outer Gneerings reef ledge with a large rocky overhang, colourful coral, and the kind of structure that keeps every pass interesting. It suits boat divers who like a roomy reef with cave-like sections, plenty of small life, and a profile that reads best when the swell is calm and the water is clear. The site has a strong photo-diving reputation, but its real draw is the mix of coral, ledges, and critters spread across the overhang and gutters.
