Relatively cheap when compared to other first world destinations. Extraordinary scenery and wildlife.
South Africa has an enormous amount to offer. For big 5 wildlife safaris, you'd want to be considering the Kruger National Park, Sabi Sands Game Reserve.
For nightlife, restaurants and exquisite scenery spend a few days in Cape Town.
Cape Town is best between November and March when it's warm and not too windy.
The Kruger Park is best towards the end of winter, before it getstoo hot and you can easily see wildlife with the foliage having lost its leaves.
