Mont Aigoual from Saint André de Valborgne

The D907 rises 27.1km through wooded valleys and open mountainside, gaining 1,227m to 1,557m. The average gradient of 4.5% disguises ramps of 9.9% — the kind of gradient that turns plans into prayers. 11 hairpins punctuate the ascent, offering brief respite in the corners before the gradient bites again. The road reaches 1,557m — high enough to feel the altitude on tired legs. Located in Languedoc-Roussillon, France.
