At Maropeng, known as the Cradle of Humankind, travelers can learn about the history of humans as a species. The first fossilized skull of the hominid Australopithecus (nicknamed “Mrs. Ples”) was discovered here. The Maropeng facility offers a wide range of activities, including drives through the lion and rhino park in an open-top game-viewing vehicle, hot-air ballooning over the Highveld, and exploring the world below in the Sterkfontein Caves.
