Beautiful on both sides! From Mervelier, you first have to conquer a few short, steep ramps, then the road flattens out and you go directly along the stream through the narrow valley. From the Scheltenmühle onwards, it climbs steeply again; there are 300 meters of altitude gain from there to the pass crossing. At the very top, a short detour to the Vorder Erzberg mountain inn is worthwhile. There you can refuel and enjoy a fantastic view towards Passwang.

The beautiful old stone railway bridge crosses the valley with the road to the Col des Rangiers. The slender yet mighty bridge arches can be seen from afar and also mark the beginning of the climb.

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.
