Aliwal Shoal,
where the raggies gather.

A few kilometres off Umkomaas lies a fossilised sand dune turned reef, and every winter hundreds of ragged-tooth sharks gather on it. Aliwal Shoal is one of the best-known dive sites in the world, and it is 20 minutes from the chalets.

What you see

The shoal is named after the Aliwal, a ship that nearly ran aground on it in the 1840s. The reef is the remains of an ancient sand dune, now covered in hard and soft corals and home to turtles, rays and reef fish.

Ragged-tooth sharks (raggies) arrive in the winter months to mate, and dive operators report them roughly from June to November. Tiger sharks are seen in summer, and dolphins, whale sharks and humpback whales pass through in season. The wrecks of the Produce and the Nebo lie close by.

Diving, snorkelling or a boat ride

Dive centres in Umkomaas run daily reef and wreck dives, PADI courses for beginners, snorkelling trips and ocean safaris, including Sardine Run trips in June and July. Some also offer baited shark dives.

The boats launch through the surf from the beach, which is an adventure in itself. Trips depend on the sea, so book early in your stay to leave room for a weather day.
