Although South Africa doesn't offer a camping card, a
Wild Card can be an option especially for customers who have an interest in wildlife. The Wild Card can be a good solution for people who plan on staying at certain national parks during their trip. However, note that the Wild Card card only gives access to certain campsites or parks around the country.
See their
website for more information about participating campsites and purchase options. It will cost a small fee to stay at any campsite in South Africa, but whether you should buy the camping card or not really depends on your preferred route and schedule around the country.
