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.
Grossi Wasserleitu von Varen - Suone Neuf
The Grossi Wasserleitu or Bisse de Varen is sourced from the Raspille; it crosses a glade and runs through the huge rock slabs of Blatte to water the meadows and vineyards of Varen. The Raspille forms the boundary between two language areas, and it shares its waters among the neighbouring communities; the Bisse Neuf also takes water from this river to slake the thirst of those living on the Venthône hills.
