The single-chamber Wonder Cave, deep under the Witwatersrand, is situated in the Cradle of Humankind World Heritage Site, one of the world's richest hominid fossil sites. It is also the third-largest cave chamber in the country. The cave, which has been open to the public since 1991, is home to fossils of rodents and birds among other small animals, and beautiful rock formations.
After an initial 90-step descent with the help of a tour guide, visitors take an elevator down to the chamber of the 60-m-deep cave. This natural wonder has spectacular cave formations. Features include rimstone pools, cave pearls, stalactites and stalagmites up to 15m in height, most of which are still growing. The cave also has its colony of bats.
Wondercave offers a variety of tours and entrance is by guided tour only. With an option of a Day tour, a night tour and an opportunity to experience an 18m abseil, visitors can enjoy this experience to its full extent. Facilities at the Wondercave also include a curio shop selling arts and crafts and a limited braai area.
