Sustenpass

The Sustenstrasse rises 27.7km through mountain forest into exposed high country, gaining 1,595m to 2,223m. The average gradient of 5.8% disguises ramps of 13.1% — the kind of gradient that turns plans into prayers. 12 hairpins punctuate the ascent, offering brief respite in the corners before the gradient bites again. At 2,223m, the summit rises above the treeline into an exposed, often windswept landscape. Located in Bern, Switzerland.
