The Cradle of Humankind is a World Heritage Site.

The Sterkfontein Valley landscape comprises a band of important palaeo-anthropological sites which have produced the remains of hominids from over 2 to 3,3 million years ago.

It is at the Sterkfontein site that the famous Mrs Ples (Plesianthropus transvaalenis) was discovered by Dr Robert Broom, who lived there about two million years ago.

This ancient cave system has over the years revealed a sequence of deposits with fossils dating from about 3.5 to 1.5 million years ago.

At a depth of 40 metres is a perfectly calm underground lake.

The Sterkfontein dolomite caves are open every day of the year except Christmas and Easter.

Tours through the cave run every half an hour, with the first tour leaving at 9am and the last tour leaving at 4pm.

Another popular cave which does tours is Wonder Caves.

Both of these venues are suitable for children, but not easily accessible for the elderly or disabled.
