Bisses are the historic irrigation channels of the Valais. A bisse is an open ditches delivering priceless water from mountain streams – often by daring routes – to arid pastures and fields, vineyards and orchards. Many bisses are still in use today and so are carefully maintained. Numerous trails accompany these historic watercourses, inviting visitors to varied hikes on historic trails.
Bisse du Ro
The upper section of the bisse has been replaced thanks to a tunnel leading through Mont Lachaux. This path is well developed for hikers, and the route includes spectacular sections of breathtaking beauty, passing between cliff walls where restored ruins can be seen.
