The Grand Bisse de Lens hike is offered here in the direction of the water flow, that is starting from Icogne to end at Chermignon-d'en-Bas. These two endpoints are served by public transport. You will walk on the trail of the structure built in the 15th century to bring water from the Lienne upstream of the hillside for irrigation. Recently, this section of the bisse has been restored to be fully rewetted. Thus the trail once reserved for maintenance of the structure, steep and without protection, is now equipped for use by everyone. Larch channels and footbridges allow water and the public to go around the Christ the King hill in a magnificent setting overlooking the Rhône plain.
OUR ADVICE
This is a Valais bisse and like many of them, it is known for its dizzying cliff crossings. If in doubt, do not hesitate to turn back rather than keep a mixed memory of it.
As of October 30, 2025, the extension from Icogne to Lienne will be closed.
