Did a Safari a few years back in South Africa, also on the edge of the Kruger National Park. Absolutely amazing! We've all seen those fabulous Animal Planet or Discovery Channel nature shows, just imagine being in the middle of one. The big 5 referred to are Lion, Leopard, Rhino, Buffalo and Elephant.

To combine a trip like that with a dive vacation, sounds like a winner to me!
