Alto de Trevélez from Órgiva

The A-4132 rises 37.4km through wooded valleys and open mountainside, gaining 1,415m to 1,528m. The average gradient of 3.8% disguises ramps of 8.9% — 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 1,528m — high enough to feel the altitude on tired legs. Located in Andalusia, Spain.
