Col de la Colombière

The D4 rises 16.2km through wooded valleys and open mountainside, gaining 1,111m to 1,613m. The average gradient of 6.8% disguises ramps of 15.4% — the kind of gradient that turns plans into prayers. The 7 hairpin turns break up the climb, each one revealing a new perspective on the road ahead. The road reaches 1,613m — high enough to feel the altitude on tired legs. Located in Rhone-Alpes, France.
