A walk along the Bisse de Lens in the Valais

The walk was part of the Journee Europeenne de la Patrimoine, which focuses of the built legacy in Europe. The theme this year was "Au fil de l'eau" which I loosely translate at "Going with the flow". The route we followed is shown (with interesting errors near cliff faces, and some extraneous data from a previous trip, unfortunately) is the Bisse_de_Lens Google Album.
