Valsavarenche

The SR23 rises 25.6km through wooded valleys and open mountainside, gaining 1,261m to 1,960m. The average gradient of 4.9% disguises ramps of 11.3% — the kind of gradient that turns plans into prayers. 13 hairpins punctuate the ascent, offering brief respite in the corners before the gradient bites again. The road reaches 1,960m — high enough to feel the altitude on tired legs. Located in Aosta Valley, Italy.
