Linking the Champsaur to the Dévoluy, the Col du Noyer packs one of the Hautes-Alpes’ steepest final ramps into just 7.5 km, with gradients climbing to 14% right when riders’ legs least expect such a wake-up call.
A climb of two halves
From La Motte-en-Champsaur, the first kilometres wind through woodland at a reasonable 6-7%, before the road rears up sharply in the final two kilometres, cut into the cliffside with sections close to 14%. This contrast makes the climb particularly treacherous for anyone who misjudges their effort early on.
A passage between two Alpine valleys
The Col du Noyer connects the lush Champsaur to the more arid Dévoluy massif, delivering a striking change of scenery in just a few kilometres. Regularly used by the Tour de France and the Critérium du Dauphiné as a transitional climb, it remains less ridden by cyclotourists than its more famous neighbours, despite a comparable difficulty.
Getting the climb right
A wide-range cassette helps tackle the final wall with composure, while brakes in good condition are essential for the technical descent on the Dévoluy side, where the road winds between narrow rock walls.
When to go
May to October — the road can remain closed or snow-covered in spring due to its altitude and exposure on the Dévoluy side.
Good to know
La Motte-en-Champsaur and Saint-Étienne-en-Dévoluy offer simpler, rural accommodation, ideal for riders seeking quiet between two major Alpine climbs.
