The San Bernardino Pass is an Alpine pass in the canton of Graubünden, in southeastern Switzerland. It reaches an altitude of 2063 m. above sea level and is located on the watershed between the Po basin and the Rhine basin.
At the village of San Bernardino, on the southern side (7 km before the Pass), there is the entrance of the highway tunnel (completed in 1967 and 6.6 km long), which ends at Hinterrhein, in the Rhine valley, and avoids climbing to the pass.
The actual climb begins near Soazza (500m.) And lasts for 25 km with a vertical drop of 1,500 meters and an average gradient of 6%.
The final stretch is dotted with lovely small ponds and glacial streaks and ends with the magnificent Moesola mountain lake.
Just before the steep descent to Hinterrhein there is the Hospiz St. Bernhardin (today a Gasthaus).
