Trivigno from Aprica

The SS39 rises 10.2km through wooded valleys and open mountainside, gaining 533m to 1,695m. The average gradient of 5.2% disguises ramps of 11.5% — the kind of gradient that turns plans into prayers. 19 hairpins punctuate the ascent, offering brief respite in the corners before the gradient bites again. The road reaches 1,695m — high enough to feel the altitude on tired legs. Located in Lombardy, Italy.
