Soubey, located at 476 m a. s. l. in the valley of the Doubs, is characterised by agriculture (especially dairy farming and cattle breeding). Depending on the area, the charming river is gentle and wild at the same time - a paradise for fishermen and canoeists. At the beginning, the route leads uphill via Les Hormets. At first still on a road, it soon changes to a lovely path running through pastures and along the edge of the forest.

At Moulin Jeannottat, you enter the Doubs Regional Nature Park. Its basis are the fascinating natural and cultural landscapes of the Doubs valley and its plateaus with the extensive "Wytweiden" pastures. Here, woods and open grassland alternate like a mosaic. With the Doubs at your back, you now climb, sometimes steeply, through primeval forest sections and across dreamy pastures. Les Pommerats is reached after 400 metres of ascent. Once you arrive at the high plateau of the Franches-Montagnes, you enter a quiet countryside with dark forests, open pastures, old trees and scattered farms, surrounded by horses, cows and sheep.

The highest point of the hike is reached at Le Haut du Bemont at 1072 m a. s. l.. The view of the Chasseral and the wind turbines around Mont Soleil is superb. From here, it isn’t far to the stage destination of Saignelégier, a village which rests on a broad ridge on the Jura plateau. The main town of the Franches Montagnes is famous for the Marché-Concours, the national festival of the Franches-Montagnes horses, which takes place every year in August.
