Pragel Pass

Steep, narrow link between Muotathal and the Klontal, gradients up to 18 percent.

The Pragelpass is a tight, lightly trafficked road over a 1548m col between Schwyz and Glarus, dropping into the serene Klontal valley with its lake. It is narrow and genuinely steep, hitting around 18 percent on the worst ramps, and runs roughly parallel to the busier Klausen Pass. The east side is closed to motor vehicles on weekends, so plan timing carefully. Mind the single-lane sections with awkward passing, the very steep pitches that punish brakes and clutch, and the weekend closure on the Glarus flank.
