Great White Shark Cage Diving in Hermanus is a 365 day-a-year activity (weather permitting). Sharks are spotted all year round. There is no need for scuba or snorkelling experience or equipment, as it is all surface viewing and novices are very welcome. You pop on a wet suit provided by the operator, grab a mask and jump into the cage, which is 3 metres high; 2 metres under water and 1 metre above it. When a shark approaches, all you do is hold your breath and duckdown into the lower section of the submerged cage. Below are a few Shark Cage Diving operators in the Hermanus and Gansbaai area.
