It was in South Africa, where we tried bungee jumping and diving with sharks for the first time. Climbing the famous Table Mountain in Cape Town via the difficult India Venster trail was also a great challenge. Apart from that, we enjoyed "the big five" on our first day in Kruger National Park, penguin beach near Cape Town and the breathtaking coast of the Cape of Good Hope.
We also visited two city centers (which is quite uncommon for tourists in South Africa) - Cape Town and Johannesburg. They are somehow controversial regarding the safety issues - if you wish to find out how it turned out for us - see the articles below.
We also went to the little country entirely surrounded by South Africa - Lesotho - which seems to be completely forgotten and ignored by western tourist. Don't miss it! More info about Lesotho here.
