About Sterkfontein#

Sterkfontein is a fossil-bearing cave complex and archaeological site in Gauteng, South Africa, and forms part of the Cradle of Humankind World Heritage Site. It is one of the world’s most important sites for early hominin fossils.

Excavations at Sterkfontein have recovered numerous hominin remains, including key Australopithecus specimens and other fauna that have informed research on human evolution; some finds date to several million years old. The site has been excavated since the early 20th century and remains an active research location.

The caves and associated interpretation facilities receive visitors through guided tours that explain the excavation history, major finds and their scientific significance. The site is located near Krugersdorp, within the broader World Heritage area northwest of Johannesburg.

  • Fossil finds: Fossils recovered include several Australopithecus africanus specimens and other hominin remains; some discoveries have ages of millions of years, including specimens older than 2 million years.
  • Visitor access: Site tours are generally guided and focus on the caves where excavations have taken place and on the interpretation of hominin fossils.

How to Get to Sterkfontein#

The Sterkfontein Caves (Cradle of Humankind) lie northwest of Johannesburg near Krugersdorp. The site is most easily reached by car from Johannesburg - expect roughly 45-60 minutes’ driving (about 40-60 km depending on start point).

There are also organized day tours from Johannesburg and Pretoria that include transfers; on-site facilities and parking are available at the visitor centre next to the caves.

Tips for Visiting Sterkfontein#

  • Book a guided cave tour in advance (guided entry only) and choose an early-morning slot to avoid peak visitor times and the midday heat at the Cradle of Humankind.
  • Combine Sterkfontein with the nearby Maropeng Visitor Centre on the same day-most visitors miss the interpretive displays that explain the broader paleoanthropological context.
  • Expect narrow, uneven cave passages on the tour and check the site's booking page for tour lengths and accessibility restrictions before you go.
