A pleasant cycling route through the Parc Naturel des Ballastieres. This former ballast extraction site is now a natural area with a pleasant walking trail a stone's throw from the city. On and around the bodies of water, nature is reclaiming its rights and many species have taken up residence there under the gaze of the Highland cows that maintain the place.
