Glas Pass and Tomül Pass

Alpine Bike Route 1, SwissMobil

A demanding bike tour takes you across the Glas Pass and Tomül Pass.

At the heart of Graubünden, mountain bikers will find two impressive crossings: the Glas Pass and Tomül Pass. To save yourself the ascent to Glas Pass you can take the Postbus from Thusis to the starting point at the top of the Glas Pass. From there, follow the signposted Alpine Bike Route 1. The first descent drops steeply down to Safien Platz. This is followed by a gentle ride through the mystical Safiental to Thalkirch and the hamlet of Turahus. From here, the trail ascends steeply on the «Polenweg» and to the highlight for bikers: the Tomül Pass. A technically demanding but very varied descent takes bikers down into the Valsertal. From Vals, follow the overland road along the Rhine, via Uors to Ilanz, where you can board a Rhätische Bahn train.

Length: 50 km
Height difference: 1300 m
Grade: difficult
