It is definitely worth visiting this cave. However, telephone reservations are required at +33 5 62988150 and you must be on site 30 minutes before the start of the tour. If you are lucky, you might get a spot on a later tour without registering. Here you can visit the original cave. The tour lasts 50 minutes. For us, the timing didn't work out. Behind the house, there is a nice picnic spot and you can visit the exhibition area.

A short, easy section that allows you to get from the lake to the D33. It seems to me that this section is part of several marked mountain biking routes.
