Departing from Prénovel, this route crosses characteristic landscapes of the Haut-Jura: areas of pasture, forests, valleys, peat bogs and crests.
The interpretation trail of the Nanchez peat bog, a few minutes from the route, will make you discover this surprising natural environment, so precious to preserve because it is home to a rich variety of plant and animal species. The hike is enhanced by the passage to the belvederes of the Virgin and the Mill, arranged on the high points of the circuit. These belvederes will allow you to discover the peaks of the Haute Chaine du Jura and the Alps in clear weather.
This Jurassic Velo Tours route has digital guidance only. You will not find any markings on the ground. Let yourself be guided with the Jurassic Vélo Tours app, which can be downloaded for free from Google Play Store and App Store.
