Petit Byahau - St. Vincent
Seal Island in False Bay is not a dive for the faint of heart, but it’s an absolute spectacle if you’re up for it. We’re talking about diving amongst 50,000-60,000 Cape fur seals, a chaotic, barking, torpedoing mass of energy that will swim right up to your mask. Visibility averages about 6m, which sounds low, but it adds to the drama, seals appearing and disappearing from the gloom. Our favourite time to visit is when the pups are starting to get comfortable in the water, usually around late summer. They’re incredibly playful, nipping at fins and camera domes. You’ll spend most of your dive just watching them zip past, the light filtering down through the kelp, their curious eyes right on you. Keep an eye out for the Broadnose Sevengill sharks too, though encounters are rare, they do cruise the area. It’s an easy dive, maxing out at 12m, but the sheer volume of wildlife makes it exhilarating. This dive is for those who prioritise a truly wild, high-energy animal encounter over pristine reefs. It’s loud, it’s lively, and it’s genuinely unlike anything else.
