Le Sapoitier" is an ideal introduction to mountain biking, combining undergrowth and meadows. It starts in Champagnole, the gateway town to the Haut-Jura Regional Nature Park.
The route loops through the Champagnole municipal forest, passing through the village of Sapois. From here, you can take mountain bike route 62, which explores the exceptional Ain valley between Champagnole and Sirod. The swift waters of the river weave their way between the rocks, then disappear into the depths, only to reappear further on, as wild as ever: a sight not to be missed.
Note, however, that this section extends the route by around 10km.
