The natural site of Siderobe, niched in the gorges de l'Agout, is located in the heart of the Haut-Languedoc Nature Reserve. Erosion has sculpted the granite into curious landscapes. The most impressive feature is the balancing granite block, Peyro Clabado. The circuit (53km) takes you to Sept-Faux Rock, St-Dominique Grotto, the chaos of Resse, the Three Cheeses and the Goose Rock. A pause at the Maison du Sidobre will give you an idea of the richness of one of the most important granite deposits in Europe.
