An old Alpine crossing beside its motorway tunnel.

The Hauptstrasse 13 over the San Bernardino Pass at 2,066 m links the Hinterrhein and Mesolcina valleys, the original pass road now a quiet, sweeping alternative to the motorway tunnel below. Flowing hairpins and lake-dotted heights; mind the cyclists, motorbikes, and snow that closes it in winter.
