From the centre of Faucogney, you'll head for the Plateau des 1000 Etangs, cross the Upper Ognon Valley to reach the first Ballons des Vosges, still in the Haute-Saône département at an altitude of 1,000 metres. The descent to the Plateau will lead you between ponds, wooded paths and torrents. An accomplished sportsman. https://ignrando.fr/fr/parcours/124520-circuit-vtt-n-52-du-piemont-vosgien-faucogney-et-la-mer-vosges-du-sud
