Inside Edge is the inshore wall of Aliwal Shoal, rising from sand into pinnacles, gullies, ledges, caves, and overhangs. It is a boat-access reef dive with a photo-friendly mix of reef structure and small-life hunting, plus seasonal shark and ray traffic when the water lines up. The site rewards steady buoyancy, a calm launch window, and divers who enjoy structure rather than open-water drift.
