Lac de Tseuzier (Bus stop "Rawil, barrage") – Er de Chermignon – Plans Mayens (Crans-sur-Sierre) – Montana

Since you are not returning to the same place, we recommend riding the PostBus from Sion to Lac de Tseuzier. From this reservoir lake, a leisurely hike on Alpine paths takes you in 90 minutes to Alp Er de Chermignon. It was here that the precariously built Bisse started its course in the direction of Crans-Montana.

The rock faces over the Bisse are steep and it is evident how much work is involved in maintaining them. A little further on you will see the vertical rock faces descending down to the former watercourse. The railings, steel cables and wooden footbridges enable you to walk this exciting route. But nevertheless, sure-footedness and good boots are a precondition for this hike. Markers along the trail provide information on historic events.
