Sustenpass from Wassen

The sustenstrasse rises 17.8km through mountain forest into exposed high country, gaining 1,360m to 2,276m. Averaging 7.6%, the road kicks to 12% at its steepest — a serious ramp that demands respect. The 3 hairpin turns break up the climb, each one revealing a new perspective on the road ahead. At 2,276m, the summit rises above the treeline into an exposed, often windswept landscape. Located in Uri, Switzerland.
