Boat-access inshore wall at Aliwal Shoal with sharks and macro life
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.
