Cage dive with sharks or stay aboard and watch these magnificent beasts from above! Shark diving is definitely the most well known industry in Cape Town. Home to around a quarter of the world's shark species, it is the best place for underwater shark diving and shark snorkeling. The most common method of diving with sharks is cage diving. The cage, which is attached to a boat, is typically a rectangle and fits about four divers at a time. Once in the water, divers have a largely unobstructed view of the sharks as they swim within feet of the cage. Go from fearing the shark to creating memories with them.
