Observing and diving with Great White sharks can provide one of the most thrilling experiences of a lifetime. Numerous operators run cage diving trips around Gansbaai (two hours from Cape Town) where the open stretch of water between Dyer Island and the mainland is referred to as the shark diving capital of the world. Trips aim to educate people about the Great White shark as well as provide an up close and personal encounter from within the safety of a cage lowered into the water from the boat. People have the opportunity to watch and photograph the sharks feeding at the surface alongside the boat, and the very brave can then take turns inside the cage, which is let down about three feet (1m) below the surface of the water. Great White sharks are in the Gansbaai area all year round, but are here in their highest density during the winter months from May to October.
