Cape Town is beautiful.
The Kruger National Park is a must.
A lot of tourists go on tours of Soweto.
There are reserves where you can play with baby lion cubs etc. Johannesburg has a lot of top class restaurants with great food and although expensive for someone earning rands, it's a steal for a tourist travelling on euros etc. over 4 years ago
