Situated in the commune of Orgnac-l'Aven, close to the Ardèche gorges and the Cèze Valley, the Orgnac pothole, listed as a Great Site of France, will take you on a fabulous journey through an enchanting underground world...During the hour-long guided tour, admire its huge caves decorated with splendid concretions, its forest of "stacked plates" (stalagmites), its "palm trees" which can reach heights of 17 metres, and its majestic draperies. In the Red Room (Salle Rouge) at a depth of 121 metres, a completely enthralling sound and light show is a wonderful way to round off your exploration of the cave.
The museum called the Prehistoric City (Cité de la Préhistoire) present the archaeological heritage of Ardèche, as well as the everyday life of prehistoric humans, in a fun, interactive fashion.
