About this site
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.
