Six km from the picturesque village of Cerdon on the RN 40 country road between the gorges of l'Ain and the Lake of Nantua. Facilities include a vast parking area for cars, picnic places in the woods, a kiosk with a bar and good walking country.

A short ride on a miniature train takes the visitor to the entrance. Here a vast network of halls and galleries leads to a splendid panoramic view point in a cliff face. Many years ago the largest chamber in the cave was used as an underground store room for cheese. The magnificent speleothems make this a trip to remember.
