    StandoutExceptional marine biodiversity

    Blow Hole often gets overlooked, labelled as a training site, but that’s a disservice. We love dropping in here for a relaxed dive, especially when the south-easter’s blowing and other sites are a mess. It's a proper Cape Town shallow dive, maxing out around 18 metres on a good day, but most of the action sits around 5-10 metres. You’re pretty much guaranteed to find pyjama sharks tucked into the kelp, sometimes so many you’re counting them on every rock. We often spot shy sharks too, and the odd puffadder shy shark if you’re looking carefully. The sandy patches between the kelp forests are great for critter hunting, and we’ve seen everything from tiny nudibranchs to bigger rays cruising through. The water here usually has that classic Cape green tint, but on a good day, the light filters through the kelp like stained glass. It's an easy boat dive, no tricky entries, making it perfect for shaking off the dust or just enjoying a calm swim through the kelp. While it might be a training ground, we think it’s a brilliant spot for any diver who appreciates the subtle beauty of temperate reefs and a solid shark encounter.
