Exploring the Legendary Dive Sites of Aliwal Shoal
Aliwal Shoal offers a variety of dive sites that cater to divers of all levels, but for seasoned divers, the real treasures lie in the deeper, more complex sites. From shark encounters to wreck dives, each site offers a unique adventure.
Raggie’s Cave is a popular site for those seeking to encounter the ragged tooth sharks (locally known as raggies). This site features a massive overhang with two swim-throughs, a cave with a large sand patch, and a long overhang that provides a perfect environment for these fascinating predators. The cave is a great site to witness the impressive presence of raggies alongside other marine life like moray eels and large game fish.
Cathedral is another must-see dive site, a stunning circular cavern that spirals upwards to an 18-metre pothole entrance. A massive arch dominates this amphitheatre-like hole, with light filtering through in a way that mimics church windows. The arch is encrusted with marine life, and divers can expect to see raggies, rays, cuttlefish, and the elusive frogfish.
For a more adventurous dive, head to the Pinnacles, a ridge of sharp rocks and jutting overhangs that descend into deep potholes and hidden caves, giving you a delightful blend of adventure and discovery. Known for its abundant marine life, including rays, turtles, and colourful fish, the site also features remnants of the Produce wreck, with metal shards scattered across the reef.
For those who enjoy drift diving, South Sands offers a fantastic starting point. The strong current here makes it a thrilling drift dive, where you might spot rays, guitar fish, and sand sharks that bury themselves in the expansive sand.
If you're after something suitable for Open Water qualified divers, Chunnel is a great option. With a maximum depth of just 14 metres, it’s a relatively shallow dive that still offers plenty of excitement. Sharks, turtles, and rays can all be found here, making it a relaxing yet rewarding experience for divers looking for a calmer but vibrant dive.
North Sands is another excellent dive site with a sandy bottom. Here, divers can often see dolphins, rays, and giant guitar fish, making it a serene yet exciting spot for those looking to relax and enjoy the underwater world.
For more advanced divers, Inside Edge provides a fantastic opportunity for wall diving and drift diving with a strong current. Located on the shoreward side of Aliwal Shoal, the site plunges 10 metres from the reef plateau to the sand. Here, you can encounter a variety of marine life, from macro shrimp to nudibranchs, and even sharks. The maximum depth is 25 metres, making it site more suited to experienced divers.
Finally, Howards Castle, located further south than the rest of the Shoal, is a site known for its dramatic ledges, overhangs, and swim-throughs that resemble a castle. This site is a favourite for baited shark dives, where divers may encounter blacktips, raggies, and other exciting species. The site is renowned for its diversity and dramatic underwater architecture.
Shark Dives: Face-to-Fin with the Ocean’s Apex Predators
For many divers, the real draw is the sharks. From bull sharks and tiger sharks to hammerheads and blacktips, the predator action here is nothing short of spectacular.
The famed Shark Alley is a must-visit for those seeking a close-up encounter with the ocean’s ultimate predators. Here, divers can enter crystal-clear waters where the world’s most feared species glide silently past. For those looking for an adrenaline rush, this is the ultimate diving experience.
Wreck Dives: History Beneath the Waves
In addition to the adrenaline-pumping shark encounters, Aliwal Shoal offers wreck divers a chance to explore fascinating pieces of maritime history beneath the waves. The SS Nebo wreck, a 112-metre steel-hulled freighter, lies in shallow waters near the Shoal and serves as both an artificial reef and a habitat for countless species of marine life. As you descend onto the wreck, you’ll encounter schools of game fish, large groupers, and perhaps even a curious turtle or two.
The Produce wreck, another popular dive site, is a cargo ship that sank in the 1970s and has since transformed into an artificial reef. Over the years, the wreck has become home to diverse marine life, including rays, moray eels, and large schools of fish. The intricate structure of the wreck makes it an interesting and complex site to explore, offering new discoveries with each dive.
