Yes they are in the same area, about 10km apart. The Sterkfontein caves and visitors centre is done by inter alia sowetotours who collect in Johannesburg. The Wonder cave is in the Rhino and Lion Nature Reserve. If you are here on a sunday morning they feed the lions and cheetahs and wild dogs. Most travel agents and hotels will be able to give you other tour operators names. Hope this helps.

Hi Karen, I would say 5-6 years recommended and older, but young children who are interested can also go. The entrance is down some steep stairs and the floor in the cave may be uneven or wet and there are bats. So the children need to be well controlled and monitored. Consider claustrophobia and fear of heights, but if the children are not prone to phobias, then that's OK. Younger than 3 are free but decide how much they will take in. Enjoy,
