The 15 most beautiful caves in France

Beneath the limestone massifs of the Lot, the Cévennes, the Vercors and the Pyrenees, millions of years of erosion have sculpted a parallel world: underground rivers, forests of stalagmites, translucent concretions and sometimes cave art tens of thousands of years old.

This selection brings together fifteen of the most spectacular caves and avens in the country, from great underground cathedrals developed for visitors to major prehistoric sites such as Lascaux and Niaux. A way of discovering France from below, at a constant temperature in summer and winter alike.
