Tourists with an interest in natural history, or those who want to see more than just sunny beaches on their travels, might be tempted by the Sterkfontein Caves.
Located an hour away from both Johannesburg and Pretoria, they could be a perfect place to spend a day out on a South Africa holiday, as they offer a variety of experiences to visitors.
At the top of the to-do list may be a trip into the caverns themselves, where several notable scientific discoveries have been made over the years. Of these, there are two that stand out.
Mrs Ples is the name given to a skull that is around 2.1 million years old and Little Foot is a nearly-complete skeleton that dates back more than three million years. Seeing these early glimpses of humanity may be a humbling moment for some explorers.
The site is part of the wider Maropeng centre. In Setswana, the native language of the area, the word means "returning to the place of origin". Entry to the caves costs R120 (£11) or R80 for registered pensioners.
