Col de l'Iséran from Lanslebourg

The D902 rises 32.2km through alpine terrain above the treeline, gaining 1,451m to 2,770m. The average gradient of 4.5% disguises ramps of 10.6% — the kind of gradient that turns plans into prayers. The 5 hairpin turns break up the climb, each one revealing a new perspective on the road ahead. The summit at 2,770m sits above the treeline, where the air thins and the views extend to distant peaks. Located in Piedmont, France.
