I am a solo female traveler heading to South Africa for work in March. Our group is spending a few nights in Cape Town at Mount Nelson Lodge then flying to Kruger National Park for a 3-day safari, staying at the Kapama River Lodge. I would like to extend my stay for 3-4 days and will be traveling alone those days. Is there a recommended excursion or location that is easily reachable from Cape Town? What are the recommended small group tours in case I go that route? I am just getting started with my research and don't know much about the area yet. Thanks in advance.
