The artistic marvels here are all created by nature, not man; this cave is a geological wonder of crystals, stalagmites, and stalactites. The cave is about 1.5km (1 mile) northwest of Les Eyzies on the left bank of the Vézère (signs point the way on D47). While the venue does not limit visitor numbers, you might still get stuck in a line in the summer. Ensure you have a sweater, as it gets chilly underground.
