You suffer in this climb. But its irregularities and proximity to forest / river makes it unique ! The poor road state makes it wilder, but the surface still completly OK for bike road. Very few cars.... read more

A climb that requires experience and training.
I suffered a lot on this climb and the descent of around 1.5 km does my legs and morale a world of good.
A very irregular climb, it always surprises, even when I did it the second time during the bridge of the climb. This climb is not to be taken lightly.
Nice descent on the Grenoble side, but the road on the Brédavière side is in very poor condition.
Climbed on 30/05/2025 and 1/06/2025

Montée qui demande de l’expérience et de l’entraînement.
J’ ai beaucoup souffert dans cette montée et la redescende de 1,5 km environ fait extrêmement du bien aux jambes et au moral.
Montée très irrégulière, elle surprend toujours, même lorsque je l’ai fait la deuxième fois durant le pont de l’ascension. Il ne faut surtout pas la prendre cette montée à la légère.
Belle redescende du côté de Grenoble, mais du côté de brédavière la route est en très mauvaise état.
Monté faite le 30/05/2025 et le 1/06/2025

A narrow road, in very variable condition (holes, gravel), is already an adventure :)
The gradient is very irregular, with some very difficult sections, and others where you can take a rest.
The last few kilometres after the descent are the hardest, steep and steady.

Une route étroite, peu fréquentée, dans un état très variable (trous, gravillons), c'est déjà une aventure :)
La pente est très irrégulière, avec quelques secteurs bien difficiles, et d'autres pour se reposer.
Les derniers km après la descente sont les plus durs, raide et réguliers.

This climb gave me a real Ardennes feeling. The road is nowhere really wide, almost no traffic or other cyclists and constantly sheltered by the forest around you. A big contrast with the wide Alpine cols in the area.

Deze klim gaf mij een echt Ardennengevoel. De weg is nergens echt breed, bijna geen verkeer of andere fietsers en constant beschut door het bos rondom je. Een groot contrast met de brede Alpen cols in de omgeving.

I like this side very much because you can go very quickly into the walls because afterwards there is plenty of room to rest, but the other side is still more interesting.

J'aime beaucoup ce versant car on peut se permettre d'aller très vite dans les murs car après il y a de quoi se reposer, après l'autre versant reste tout de même plus intéressant

It's hard to do more different from the other side of the same pass. This one doesn't offer any remarkable viewpoint, we are from Brévardière in a very dense forest on a narrow road. Moreover, it is a particularly irregular climb with slopes that are sometimes harmless, sometimes very steep (notably this long kilometer section at 14-16％ after Brévardière) and there is even a descent, which hurts the legs when it goes back up afterwards... All this makes it a dream climb for a pure climber who likes changes of pace. Another difference with the other side, particularly unfortunate : the road is often in bad shape. On the way up, it's fine, but on the way down, it's better to be careful.

Difficile de faire plus différent de l'autre versant du même col. Celui-là n'offre pas de point de vue remarquable, on est à partir de Brévardière dans une forêt très dense sur une route étroite. De plus c'est une montée particulièrement irrégulière avec des pentes tantôt anodines, tantôt très fortes (notamment cette longue portion kilomètre à 14-16％ après Brévardière) et il y a même une redescente, ce qui fait mal au jambes quand ça remonte ensuite… Tout cela en fait une ascension rêvée pour un pur grimpeur amateur de changements de rythme. Autre différence avec l'autre versant, particulièrement malheureuse : la route est souvent en mauvais état. En montée ça passe sans problème, en descente mieux vaut être prudent.
