Cycle path that connects Morgex to La Salle within the Marais Nature Reserve. The route follows a stretch of Dora Baltea crossing its alluvial plain, where there are lakes, marshes and hygrophilous woods. It is almost 4 kilometers long and allows you to avoid the Aosta state road which can be busy at peak times.
