シエールの峡谷・トップ4

The valley is not accessible by road from its upper part and offers optimal conditions for peaceful walking and wildlife observation. The landscape has typical ice age features: glacial humps, moraines and so-called "Karmulden", i.e. cirque hollows formed by past glaciers.

It is notoriously one of the main geologically unstable regions of Switzerland. The Illgraben massif is made up of dolomite, limestone and quartzite. Several times a year, mudslides from the Illgraben make the Rhône murky until it reaches Lake Geneva, located 90 kilometers downstream.

From this location you will enjoy an excellent view of this beautiful, eroded valley, with layers of crumbly rock visible creating stunning colors. This valley is almost reminiscent of the distinct landscapes one might find somewhere like Iceland. Be sure to take a break here to let your brakes cool a bit before speeding back down the hillside.

The Raspille forms, together with the Pfynwald, the language border between the German-speaking Upper Valais and the French-speaking Central and Lower Valais.
