Sodwana Bay scuba diving

Why Sodwana Bay?

Sodwana Bay lies in the far north of KwaZulu-Natal, not far south of the border with Mozambique. The reefs here are the southernmost coral reefs in Africa, kept alive by the warm Agulhas Current flowing down from the tropics. Hard and soft corals, sponges and a huge variety of tropical reef fish make Sodwana feel very different from the rocky reefs further south.

The bay sits inside the iSimangaliso Wetland Park, which was listed as South Africa's first UNESCO World Heritage Site in 1999. The park protects a long stretch of coast, lakes, wetlands, forest and sea, and its marine section is a protected area with rules on fishing, anchoring and diving. For divers that means healthy reefs and a relaxed, outdoor feel: Sodwana is a place of campsites, lodges and dive camps rather than big hotels.

It is also one of the most popular places in South Africa to learn to dive. Many South African divers did their first open water dives at Sodwana, and the shallower reefs are well suited to training, while deeper sites and the canyons offshore give experienced divers plenty to explore.

The reefs: named by the mile

Sodwana's reefs are known by their approximate distance from the launch site at Jesser Point. That makes the dive map easy to learn: the further the reef, the longer the boat ride.

1. Two-Mile Reef

   Most dived · Range of depths

   The best-known and busiest reef, a long stretch of coral with many named sites along it. Close to the launch and with sections suitable for both training and experienced divers, it is where most visitors do the bulk of their dives. Expect big shoals of reef fish, moray eels, rays, and turtles resting under ledges.

2. Four-Mile and Five-Mile Reef

   A little further · Coral gardens

   A short run north from Two-Mile, these reefs are often praised for their coral cover, including delicate formations that need careful buoyancy. Divers who have been to Sodwana before often come back for these.

3. Seven-Mile Reef

   Longer boat ride · Turtles and big fish

   Further from the launch and dived less often, Seven-Mile is known for turtles and larger fish and has a wilder feel than the reefs closer to home.

4. Nine-Mile Reef

   Furthest regular reef · Conditions permitting

   The longest regular trip, usually only run when the sea allows. Ask your dive centre: it is a good choice for a day when you want something less visited.

Further offshore, the shelf is cut by deep submarine canyons. In 2000, technical divers exploring Jesser Canyon found living coelacanths, the "living fossil" fish once thought to have been extinct for millions of years. They live far below recreational depth, so you will not see one on a normal dive, but the find put Sodwana on the map for scientists and divers around the world.

What you will see

Sodwana is a place for reef life of every size. Common sightings include clownfish in anemones, butterflyfish and angelfish, triggerfish, large groupers and potato bass, moray eels, octopus and nudibranchs. Turtles are seen on many dives. Rays, reef sharks and the occasional guitarfish turn up on the sandy edges of the reefs.

The coast is also part of something bigger. The beaches of Maputaland, north and south of Sodwana, are nesting grounds for loggerhead and leatherback turtles in the summer months, and humpback whales pass offshore on their winter migration, often seen and heard from the boats. Whale sharks visit these waters in the warmer months too, though sightings are never guaranteed.

How the diving works: surf launches

There is no harbour at Sodwana. Dive boats, usually rigid inflatables, are launched straight off the beach and driven out through the surf. The skipper times the waves, the crew push the boat out, and divers hold on to foot straps or ropes as the boat punches through the break. Coming back, the boat is run up onto the beach at speed. It is exciting, safe when you follow the briefing, and part of the Sodwana experience.

Diving is normally from these boats as backward rolls, with everyone going in together. Some reefs have current, so drift dives with a surface marker buoy are common. Your dive centre will brief you on the launch and on the dive plan. If you are prone to seasickness, take precautions before the launch rather than after.

When to go

Sodwana has diving all year. The water stays warm, and most divers wear a 5 mm wetsuit, perhaps with a hood in the cooler months. Summer brings the warmest water and the turtle nesting season on the beaches. Winter is the season for humpback whales. School holidays and long weekends are very busy, because Sodwana is a favourite holiday spot for South Africans, so book accommodation and dives early if you travel then. See our South Africa dive trip planning guide for the full seasons picture.

Getting there and staying there

Sodwana is remote, which is part of its charm. Most visitors fly into King Shaka International Airport near Durban and drive several hours north, or combine Sodwana with a safari in the game reserves of northern KwaZulu-Natal. Accommodation ranges from campsites in the park to lodges and dive camps near the bay. This part of the country is a malaria area, so ask a travel clinic for current advice before you go.

Remember that you need a permit to dive in South Africa's marine protected areas, and Sodwana is inside one. Your dive centre will tell you how to get it.
