Built in the fourteenth century and entirely piped in the middle of the twentieth century, this bisse was once called the Bisse d’Amont (up river).  There are explanatory educational panels explaining the social organisation and the irrigation rules along the trail. 

Total length : 6 km.

Altitude : Between 1450 and 1750 metres.

Route time : Approximately 2 to 3 hours without the return trip. 

Location : Betwen Crans-Montana  and the Tzeusier Dam to the right of the Rhône

Difficulty : The trail is spectacular and, although quite safe, passes by vertiginous cliffs and is not suitable for those suffering from a fear of heights. In the middle of the route, a spectacular suspension bridge adorns the route.

At the water intake of the bisse, you can reach the Zeuzier Dam, Bellalui, Icogne or Lens. There are sign-posts for these itineraries. For Zeuzier and Bellalui, the climb is quite steep. For Icogne and Lens, the descent is also steep.

A very beautiful and impressive trail for the sure-footed walker. You should only tackle this walk in dry weather and during the summer months. It is strongly discouraged during the winter. 

At the water intake of the bisse, to reach the Zeuzier lake there is a 400 metre climb and a 200 metre descent. For Belle Lui, there is a 600 metre climb. For Lens or Icogne there is a 600 to 800 metre descent. You will find many beautiful places to picnic.

Crans-Montana is served all year round by public transport. For the Zeuzier dam (or Rawyl lake), public transport is only effective in summer.
