Rated as a world class dive site, Aliwal Shoal is a fossilized sand dune that lies about 4km offshore from the small coastal town of Umkomaas, on the KwaZulu Natal South Coast.

‘The Shoal’ gives divers the unique opportunity to experience wreck, reef and seasonal shark diving at the same site. Aliwal Shoal boasts an abundance of aquatic life from nudibranchs to manta rRays, including turtles, dolphins, eels and a great variety of tropical fish species. During the winter months the ragged tooth sharks congregate on ‘The Shoal’ to mate.

The baited shark dives here at the Aliwal Shoal are one of a kind, and something that must be done at least once during your time here. With two baited drums full of local sardines and fish oil, the drums slosh in the current creating a scent trail that the resident oceanic black tip sharks follow in to investigate. During the summer months tiger sharks are seen frequently and can be accompanied by a shy bull shark at times. Hammerheads can be seen as they migrate past in the summer months, as well as the odd great white shark. You never know what you may see on the Aliwal Shoal Baited Shark Dive. There is NO feeding/touching on this dive. It’s a great opportunity to get up close and interact with sharks in a positive manner while capturing the experience on camera. 

 The Cathedral

Quite possibly the most well-known site at the Aliwal Shoal. Sitting at 27m, this is an advanced dive site. A photographer’s dream, especially on a sunny day when beams of light illuminate the natural amphitheatre of the cathedral mimicking the light shining through church windows. The Cathedral is often filled with ragged sand tiger sharks (seasonally), schooling yellow and black striped coachmen and a few resident potato bass. If you keep your eyes peeled, you’re sure to find various species of nudibranchs and the beautiful paper or leaf fish. Don’t forget to look up, as hammerheads, humpback whales and the elusive great white shark have all been seen here.

Raggies Cave

This is a special dive site for new and experienced divers alike. Raggies Cave is a long cave sitting at 18m on the outside edge of the reef where the ragged sand tiger sharks aggregate during mating season. With something for everyone, Raggies Cave is rich in a variety of marine life, from sharks and rays to eels, nudibranchs and paper fish. As a bonus, there’s a large sandy patch in front of the cave where the Raggies like to congregate and roll in the sand to get rid of loose teeth and parasites. This makes it a great place to spend a few extra moments collecting shark teeth in the sand.


This diverse site is located on the inside edge in the middle of the reef and has two different caves. One is a picturesque swim-through around 3-4m in length where pineapple fish used to be seen frequently. The other cave is where sharks like to congregate in groups of anywhere from 10-20 individuals. With a max depth of 12m, this is a popular site for OWD and DSDS, as well as snorkelers and free-divers with the shallowest part of the ridge at only 5m. A variety of species off rays are also seen here including spotted eagle rays and the occasional manta ray.

Produce Wreck

The MV Produce is a large Norwegian cargo ship that sank in 1974 just a kilometre from the Aliwal Shoal. Laying almost parallel to shore, this wreck is easily navigated in both a N/S or S/N current and is best when the current is slow. At 168m in length, this impressive wreck is an advanced dive site laying at 32m with her shallowest points around 14m. The wreck is broken into three parts; with room to swim around and enter if qualified and planned. Teaming with life such as Moray eels, scorpionfish, brindle bass, large shark species and the endemic Harlequin goldie, the MV Produce is a dive not to be missed.

North Sands

North Sands is a big sandy patch that lays at the northern tip of the reef with a depth of between 12-15m. With its shallow depths, this is also a great site for snorkelers and free-divers as well. Its location at the edge of a drop-off brings in game fish such as barracuda and waho that like the crossing from deep to shallow. There are also lots of rays, including devil rays and manta rays, and ragged sand tiger sharks are seen here seasonally.

Howards Castle

Howards Castle is 2km further south than the rest of the reef and between 22 and 25m in depth, this dive site is best navigated by experienced DMs. This is where the baited shark dives are, so you’ll likely see oceanic black tips, the occasional tiger shark, and trevally on your safety stop. As you may have guessed, this site’s appearance mimics a castle, with lots of ledges, overhangs and swim- through caves where ragged sand-tiger sharks like to hangout. With macro finds such as nudibranchs and a few of the last known elusive pineapple fish on the Aliwal Shoal, this is a dive to enjoy slowly.
