As soon as the city centre of Delémont is behind you, you find yourself in an expansive hilly region: The route leads up to the Les-Rangiers chain, where on the pass of the same name, a racy descent begins to the deeply-carved-out valley of the Doubs. The route follows the quiet river to end in the historic town of St. Ursanne.

From the medieval town of Delémont, capital of the young canton of Jura, the Jura Bike route leads up to the Les Rangiers chain. Near the eponymous pass that connects Delémont with the Ajoie region, you plunge deep into the solitary Jura area. You pass Col de la Croix and then, with a fast downhill run, you enter the narrow valley of the Doubs. Here, the river forms a winding border here between France and Switzerland. There are few other rivers that move as haphazardly as the Doubs. And this is how it got its name: in Latin «dubius» means indecisive. The likes of us, however, are not indecisive in the least. We follow the banks of the Doubs, according to plan, to the picturesque village of St-Ursanne with its medieval buildings. The village is gem without a doubt, and a perfect day’s destination on the mountain bike route through the Jura.
