South Africa is, if not all, then mostly about nature (there is the Apartheid Museum of course that is a must see), or rather the resourcefulness of nature in the varied ways she expresses herself.
Do the popular thing by going on a safari to see the Big 5 and then give the action a bit of twist; Ride an ostrich, pet a crocodile, go Cage diving with the great whites, sit atop a horse as giraffe and wildebeest run by, try not to fall off your tree house, take your pick between swimming with penguins, turtles and dolphins, whale watch during your drive down the Garden route.
If that doesn’t set your adrenaline flowing, take a deep breath and….

Mountain bike up the Table Mountain, play a round of golf, bungee jump off the Bloukrans Bridge, surf at Long beach, canoe down the Orange River, catch sardines by the bucket, take a micro light flight over the South African coastline or skydive over Mossel Bay.
Time to pace it down a bit?
Enjoy the wines and cuisine at a vineyard around Cape Town, peer down the big Hole at Kimberley, take the Blue Train to see the countryside in luxury or better still sprawl at Robberg beach while whales and dolphins perform for you against an awe inspiring sunset!
