Where else can you dive with seven-gill sharks in a prehistoric kelp forest, explore old navy shipwrecks, and possibly spot breaching great whites – all in the same bay? False Bay, nestled in the southwest corner of South Africa, might be the most diverse diving destination you've never heard of.
This remarkable bay, tucked between Cape Town's iconic Table Mountain and the rugged Hottentots Holland range, offers experiences you simply can't find anywhere else in the world.
1. The magical kelp forests
Step into a living fossil: False Bay's kelp forests are descendants of marine ecosystems that have existed for over 100 million years. These towering underwater forests, found nowhere else quite like this, support a diverse range of animals, including gully sharks, seals, shy sharks, crabs, and small fish. In fact, these shark species (the pyjama catshark and the shy spotted-gully) are otherwise rarely seen.
Swimming between these ancient giants, which tower high above the divers, making them seem small in comparison, feels like traveling back in time. Shafts of sunlight pierce through the swaying fronds, creating an ethereal cathedral-like atmosphere that few ever experience.

2. Historic wrecks
A variety of wrecks litter False Bay’s ocean floors, especially old navy ships in Simon’s Town. A frequently dived wreck is the SAS Pietermaritzburg, a minesweeper used by the navy until 1994 when it was scuttled to form an artificial reef. The Smitswinkel Bay wrecks include the SAS Transvaal, SAS Good Hope, Rockeater, Princess Elizabeth, and Oratava.
Nature has turned these steel giants into living art galleries, with walls draped in mauve, red, and white sponges and corals. Bring a torch to illuminate the secret worlds: schools of endemic Galjoen (South Africa's national fish) dart through corridors where sailors once walked, while curious Cape Fur Seals perform acrobatics. Each wreck has become its own ecosystem.

3. Colorful reefs & macro wonders
In these cool Atlantic waters, you'll find explosions of color that rival tropical seas, but with a twist. These reefs showcase a rainbow of sea fan forests, sponges, and corals instead of hard corals. What makes them truly special is their location: where else can you find technicolor reefs thriving alongside prehistoric kelp forests? Large boulders form swim-throughs, which create interesting typography to explore.
Here, macro diving is spectacular, with nudibranchs in every color imaginable dotting the reefs like living jewels. Photographers will delight in finding tiny blennies and klipfish, endemic longsnout pipefish, and cryptic octopuses hiding among the rocks. The diversity of small marine life here is staggering, with many species found nowhere else in the world. Patient observers might spot the elusive paperfish or, at night, the tiny bobtail squids, making every dive a potential discovery of something new and extraordinary.

4. Amazing marine diversity
False Bay isn't just a dive destination. It's where three ocean currents collide to create one of the most biodiverse marine environments on Earth. Above water, southern right whales breach against the backdrop of Table Mountain, while great white sharks launch themselves skyward at Seal Island in hunting displays rarely seen anywhere else in the world.
But it's underwater where False Bay truly reveals its secrets. On any given dive, you might encounter endemic species found nowhere else: playful Cape fur seals performing underwater ballet, endangered African penguins, or African clawless otters playing in the shallows. The bay is home to an extraordinary cast of characters: shy sharks, cat sharks wearing pajama-striped patterns, technicolor nudibranchs that seem designed by artists, and curious octopuses that may come out to investigate your presence.
False Bay is unique not just because of the variety of life, but also because of how accessible these encounters are. Our guides will show you where to find these incredible creatures in their natural habitat, with numerous boat and shore dives available. Whether you're a novice or experienced diver, False Bay's diverse sites cater to all skill levels.

5. Where City Meets Wilderness
Few dive destinations offer the remarkable contrast that False Bay does: world-class diving on the doorstep of a major city. While most premier dive sites require remote travel and complex logistics, False Bay sits just 30 minutes from Cape Town's international airport and vibrant cultural scene. In the morning, you could be diving in a prehistoric kelp forest; by afternoon, you're sipping artisanal coffee at a waterfront café while watching African penguins waddle past urban beaches.
This accessibility doesn't just make diving more convenient; it creates unique opportunities. Night diving takes on new meaning when you can watch the sun set behind Table Mountain before slipping into waters where interesting creatures put on their own show.
The proximity to Cape Town also means you can combine world-class diving with wildlife safaris, wine tours, or climbing Table Mountain - making False Bay perfect for both dedicated dive trips and family vacations where not everyone dives.
