It is situated within the Cradle of Humankind, one of the world's richest hominid fossil sites.
Bothongo Wondercave is a massive limestone cavern located within the Kromdraai Valley, a UNESCO World Heritage site known as the Cradle of Humankind. The cave is characterized by a single, vast chamber measuring 125 meters in length and 54 meters in width. Visitors access the cavern by descending an elevator and a series of stairs to reach the floor, which sits approximately 60 meters below the surface. The interior features a significant collection of stalactite and stalagmite formations, some of which are millions of years old. The site is situated within the larger Bothongo Rhino & Lion Nature Reserve, which borders the cavern's protected area. The cave maintains a constant internal temperature, providing a stable microclimate throughout the year. It remains one of the largest cave systems in the Gauteng province.

Attempting the descent if you have severe mobility issues, as the stairs can be steep and taxing.
