This 11.5 km circuit starts from the center of the village of Servance then the path climbs up to the Côte 820. The ascent offers sumptuous panoramas on the Plateau des 1000 Étangs and the wooded valleys of the Southern Vosges. At the top, the monument of the Bataillon de Choc, built in memory of the battles of the Liberation in 1944. At La Grève, the Martin sawmill built on a bank of the Doue de l'eau, is alive again thanks to the restoration work carried out by Mr. Tuaillon and to the animations proposed by the Maison de la Nature des Vosges Saônoises.
At the entrance of Servance, a visit is not to be missed: the Saut de l'Ognon, a magnificent waterfall of 14 meters whose access has recently been redeveloped.
