About this spot
Seal Island in False Bay is an advanced dive destination off Cape Town that demands respect and experience. The site spans depths from 5 to 18 meters, with a dramatic underwater topography that keeps divers engaged. The underwater landscape features rocky formations and channels that create natural highways for marine movement. This is not an entry-level dive. The site's technical aspects—including surge, current variability, and the need to navigate confined spaces—require solid buoyancy control and solid decision-making. Divers need to be comfortable in dynamic water conditions and prepared for the energy of a working marine ecosystem. False Bay itself is one of the world's most biodiverse marine regions. Seal Island sits at the heart of that activity. The site attracts serious divers seeking raw, unfiltered underwater exploration rather than coral gardens or gentle slopes. Conditions vary, and local knowledge of tide and swell patterns is essential. Access is straightforward from Cape Town, but you'll need to arrange a boat operator familiar with the site. The area is not a marine protected area, which means access is open but responsibility for safe diving falls entirely on the diver and their guide.
