Small bones of rodents, frogs, lizards and birds have been discovered in the talus cone (cave in-fill) at the back of the cave. This cave has the best example in the region of a relatively young talus cone (a few thousand years old), which helps us understand how the older caves in the area were filled in.
Although the lower reaches of the cave were severely damaged by mining activities in the late 1800s, it contains dripstone formations as beautiful as those in the Cango Caves. It also has a resident bat population.
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. The cave, which has been open to the public since 1991, is home to fossils of rodents, frogs, lizards and birds, and beautiful rock formations.
After an initial 90-step descent, visitors take an elevator down to the chamber of the 60m deep cave. Despite damage from lime mining, the 125m-long, 154m-wide natural wonder has spectacular cave formations. Features include rimstone pools, mushroom, straw and popcorn formations, “Madonnas”, cave pearls, and stalactites and stalagmites up to 15m in height, most of which are still growing. The cave has its own colony of bats.
