Col de l’Arpettaz (42 hairpins challenge)
Average gradient: 7.1%
Maximum gradient: 12%
15 minutes to warm up
Col de l’Arpettaz is a lesser known col at the southern end of the Aravis chain. It rises up above the town of Ugine and climbs up to the shadow of Mont Charvin.
The climb starts in the village of Mont Dessous above Ugine on a relatively small lane. The ‘regular’ profile belies the steepness in parts along the 42 hairpin bends of the climb to the top.
After a few initial kilometres in open alpine meadow, the climb ramps up through a deciduous forest.
As you emerge from the forest for the final three kilometres, the Aravis chain stretches out in front of you, with the arrival at the col offering up terrific views of Mont Blanc.
