The water trail


Water trail from Champéry to Monthey along the river La Vièze.

The name Val d’Illiez comes from an old expression in the local dialect, Vau de Lie, meaning Valley of Water. This trail goes with the flow of the rivers, streams, waterfalls and springs that feed into the Vièze River between Champéry and Monthey. You will explore the vital role water plays here and the myriad ways we use and protect it. Easily accessed by public transportation, this trail can be done in stages thanks to train stops along the way.
