The Voie verte des Balcons du Dauphiné is a 18-kilometer-long secure cycle and pedestrian path, built on the route of the former Est Lyonnais railway line. It connects the medieval town of Crémieu to the municipality of Arandon-Passins, where it connects directly to the ViaRhôna.

Beautiful cycle path, mostly shaded, unpaved but rideable (I ride it with 23mm tires), which follows the old line of the Chemin de Fer de l'Est Lyonnais (CFEL)
