Seeing great white sharks hunting seals around False Bay's Seal Island is one of the most exhilarating natural displays you're likely to witness. And if witnessing it all from a boat is not thrill enough, you can get in the water (in a cage).
Apex Predators. Run by marine biologists, Apex Predators runs small trips from Simon's Town during season (February–September). If the great whites aren't around, try the Ocean Predator Trip, in which you cage dive with makos and blues. Simon's Town, Cape Town. 079/051–8558 or 021/786–5717. www.apexpredators.com.
