SUSTEN
2,224 m — the road built so people would not stand idle
The Susten is the newest of the great passes and the only one built for no reason. Switzerland raised it between 1938 and 1945, in the middle of the war, as a job-creation scheme: it connected nothing that was not already connected. That is also why it is the best drawn — the engineers had time. At the top, the Stein glacier comes down almost to the road.
CampsiteCamping Gadmen, Sustenstrasse, GadmenGPS 46.73811, 8.36228 · Open on the map →
Wide road, open bends, stone parapets. It is the pass to start with precisely because it asks nothing special of a camper. Open from late June to October. For the night: Camping Gadmen, right on the pass road, on the Innertkirchen side.

The Stein glacier is seen from the car park below the summit, and the path to its tongue is an hour there and back. The whole road is a viewpoint; there is no ticket anywhere.
