This hike, not timed and without classification, will allow you to appreciate the wonders and richness of the Haut-Jura. You will have the opportunity to take advantage of a marked out and secured course with typical Jura refreshments.

All along the route, you will have the opportunity to contemplate magnificent landscapes, with as a climax a passage by the Dôle, the second highest summit of the Jura. This summit offers a magnificent panoramic view of Lake Geneva and the Mont Blanc chain.

An experience not to be missed for nature lovers.
