Aliwal Shoal is a fossilised sand dune reef 5 km off Umkomaas on the KwaZulu-Natal south coast, internationally renowned for its aggregations of ragged-tooth sharks (grey nurse) sheltering in the caves and gutters between June and November. Oceanic blacktip sharks, bottlenose dolphins, humpback whales (winter), and large potato bass make every dive eventful, while the shoal's twin peaks — Cathedral and the Pinnacles — offer dramatic topography at 5–32 m. Boat entry through the surf is standard.
Shark Reef Marine Reserve in Beqa Lagoon runs the world's longest-running shark dive programme, with eight species reliably appearing at controlled feed dives including bull sharks, tiger sharks, and tawny nurse sharks. Divers kneel in a line at 25–30 m while sharks pass within touching distance, with the spectacle managed by experienced Fijian dive masters who have worked with the same sharks for years. The programme funds local marine conservation directly.
Protea Banks is a remote offshore reef 9 km from Shelly Beach in KwaZulu-Natal and is widely considered one of the premier shark dives on the planet. In winter (June–November) large numbers of ragged-tooth sharks congregate on the southern pinnacle, while tiger sharks, bull sharks, oceanic blacktips, and seasonal hammerhead schools patrol the northern end. Strong ocean swells, significant current, and depths of 25–40 m restrict this site firmly to advanced, experienced divers.
