Take note this is a full day excursion and there is a restaurant at the Park. Late afternoon head back to Johannesburg for a big South African supper.
Off to Soweto to see where Nelson Mandela and Archbishop Desmond Tutu once lived, the only street in the world where two separate Noble Peace Prize winners live, Take a Drive down Vilakazi street and experience the township Life and try some of the local food and share a few drinks at a traditional shebeen. For the more adventurous there is a chance to see the view of Soweto and Johannesburg from the Soweto towers two unused big cooling towers painted in a vibrate south African graffiti. And maybe even Bungee jump or bridge swing off there.
