A reasonably short drive (around 1 hour) from Jo'burg airport, north-west of the city's edge is this valley where fossils of Australopithecus have been discovered. The museum built over the top combines an exploration of the caves where the fossils were found, together with some tourist experiences such as a boat ride underground and a swirling tube to walk through. Part of the tour is guided and teaches of the importance of our common ancestry in a sensible way. The views from the ridge above across the valley are well worth the walk up to the look-out and we enjoyed lunch afterwards at the nearby resort's restaurant (a short drive away, not the conference centre next to the museum) which also afforded sweeping views of the valley. Cost-wise it was all very reasonable - 125 Rand per adult. There is a souvenir shop and cafe near the entrance, tours on the hour take about half an hour before the rest is self-guided.
