The French and European National Cycleway is a great cycleway winding along side of the Rhine Rhone Canal with very little climbing, for those who do not like to climb. However those who are climbing shy, must be aware of the wind in this area. A lot of the locks still have the former lock man’s house which adds a bit of charm to every lock. One is never alone on this route as there is a constant passing of bicycles, both leisure and racing bikes.

This region has hundreds of small fishponds, once created by monks in the Middle Ages. Today they form a patchwork of water, reeds and forest – a paradise for birds, cyclists and those seeking peace and quiet. You cycle along quiet banks, see herons take flight and enjoy local specialities such as fried carp along the way.
