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.

A real challenge uphill and downhill. At up to 25 percent, your thighs burn like fire uphill and your fingers cramp on the brakes downhill. Nevertheless, the curves are simply fun.

Located on Route 3 of La Route Verte. But on nice weekends it is busy with cars and motorcycles.
