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.

In order to make the walk more enjoyable, the itinerary we suggest on our Outdooractive map differs from the official route in two places:
-from the Bains de Val-d'Illiez to Le Pas, we suggest you take the path on the left bank
-from Chenarlier to Monthey, take the bucolic path through the Gorges de la Vièze.
