In the heart of the Aigoual massif, in the heart of the Cévennes, the Bonheur River springs forth into the open air. Upon contact with limestone, it rushes underground beneath the Causse de Camprieu, reemerging 800 meters further on. A veritable underground cathedral, guided tours last approximately 1.5 hours.
