Departure

It is possible to begin at Chermignon d’En Bas, 50 metres above the football ground just below the main road to Crans-Montana. There is a large car-park at the football ground.

Itinerary

Follow the bisse towards the statue of Christ the King. After about 3 km you reach an intersection in the main road from Lens to Granges. From the middle of the hairpin bend in the main road, follow the unpaved road for 50 metres. The Bisse de Lens continues on your left below this rough road. If you want to continue to the Bisse de Sillonin or the Bisse de Clavau, at the end of the itinerary of the Bisse de Lens when you return to a forest track, you will find all the necessary sign-posts. To reach Icogne or the dam of Rawil, continue to follow the bisse of Lens.

Public Transport Timetable

A very beautiful walk at medium altitude which can be enjoyed throughout the year as long as it is free of snow. At the mid-point, the bisse turns in the direction of the Lienne valley and follows it. At this point it becomes quite exposed and can only be walked in good weather. This stretch is impossible in winter or in wet conditions when it becomes too slippery.
