March 7, 2026, Cycleway Between Porrentruy and Fahy

Separated from the road with motorized traffic, a cycle path leads from Courtedoux to Chevenez. In some sections, it even runs completely away from the road, right through fields.

The relatively quiet main road between Courchavon and Courtemaiche runs alongside the small stream. Nothing special, but still beautiful.

Before the construction of the motorway, this was an important pass between St-Ursanne and Courgenay; now it's quieter and therefore more attractive to road cyclists. The pass itself is unspectacular—apart from the sign with the altitude and an information board about visiting the 2012 Tour de France, there's little to justify a longer stay.

A hidden gem in the Jura. A village not well-known in throughout Switzerland but well worth the visit, Home to Louis Chevrolet, inventor and mechanic, the one who founded the US motorcar company Chevrolet. The emblem on the Chevrolet car was actually the Swiss flag incorporated into the brand. There is also a watch company in Porrentruy from Chevrolet bering his name and still producing quality watches. The city has so many out door cafés with terraces.

This bridge on the Transjurane Autoroute is constructed over the cycling path from Porrentruy to Fahy. The cycling path itself is in excellent condition on mainly flat surface.

The Cycleway between Porrentruy and Fahy offers cyclists of all ages a chance to ride their bicycles with little climbing. The asphalted surface is well-kept with no bumps or holes

Nice col between Courgenay and St Ursanne. Not long but can be very hard especially when starting from St Ursanne
