The Bruche springs from the west side of the Climont at an altitude of 690m. The Bruche starts out as a quiet stream and crosses a vast sun-soaked basin, the Hang Clearing. The sometimes narrow valley gradually widens between the granite Champ du Feu mountain range and the sandstone Donon mountain range. The Bruche has a high standard of water with its four tributaries: the Climontaine, Schirgoutte, Rothaine and Framont. The category I river is heaven for fishing fans.
