Prehistoric cave art in France is not limited to the Dordogne region. A vast complex of cave art discovered in 1994 near Vallon-Pont-d'Arc in southern France is now open to the public. Scientists recently determined the paintings are as much as 37,000 years old! When some of the art there was painted, the Pyramids at Giza were still an astonishing 34,000 years into the future.
The Caverne du Pont-d'Arc is about a 90 minute drive from Avignon. I've just put this at the top of my to-do list when I visit Provence this summer!
