In the Mt Aigoual massif, at the heart of the Cevennes National Park, the river Bonheur (Happiness) has its source in the open air. It is when it reaches the limestone plateau of the Causse of Camprieu that it plunges underground, to reappear 800 metres downstream.
The name “Bramabiau” means “roaring bull” in Occitan, the local language.
The guided tour takes you on a one-kilometre circuit through the true birthplace of French potholing, along easily accessible galleries constructed in 2006 which bring you out only five minutes away from the Reception Centre.
We are happy to guide families or other groups around the circuit.
