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 de Saxon
It conveyed water from the Printse as far as Saxon, across the forests and alpine pastures of the hamlets of Nendaz, Isérables, Riddes and Saxon with their wooden chalets. Its operation required several watchmen who in turn needed huts and warning hammers. . . Maintaining the channel was a very laborious task, so its operation was discontinued. One of its huts, the Bourlâ, is still in an excellent state of preservation.
