A nice climb without much difficulty, a good warm up for an outing in the Bauges. Continue to the Col de la Cluse, which is much wilder!... read more

Note that the road was blocked off before the tunnel. No need to worry about climbing the mountain by bike around the markers. The 2025 Women's Tour has come this way.
The climb begins around an ugly roundabout in Chambéry. We climb towards Bellecombette and its buildings.
Then, suddenly, nature takes back control.
It's a fairly easy pass. Never difficult. Occasionally, there are short, flat or even downhill sections. A little traffic, but nothing stressful. Trees everywhere, masking the scenery. But the finish at the foot of Mont Granier is splendid.

A noter, la route a été récemment barrée avant le tunnel. Aucun souci pour grimper à vélo en contournant les plots. Le Tour féminin 2025 est passé par là.
On entame l’ascension autour d’un rond point moche de Chambéry. On grimpe vers Bellecombette et ses immeubles récents. Puis, subitement, la nature reprend le contrôle.
C’est effectivement un col assez roulant. Jamais difficile. Parfois, des petits tronçons plats, voire descendants.
Un peu de circulation automobile, mais rien de stressant. Des arbres partout qui masquent les paysages. Mais, l’arrivée au col est splendide. Le Mont Granier se dresse devant vous, majestueux, épuré, sûr de lui.

Climbed with Éric and Dominique on 17 July.
Despite its length and uneven gradient, this is the easiest slope to climb to the Col du Granier.
The ascent starts at the Rond-Point in the heart of Chambéry, where the traffic is fairly heavy as the D 912 crosses the Chartreuse massif as far as St Pierre d'Entremont, a village that has the distinction of straddling Savoie and Isère.
The tarmac is fine, and there are plenty of shady areas. To admire the scenery, you have to turn around as the road faces the mountains, and you need to stop just before the tunnel as you can see Lac du Bourget in the distance.
The Auberge at the top of the Granier doesn't open until 10.30am, which isn't ideal for early morning cyclists.
Ps : Numerous roads provide access to the Col du Granier, Chambéry ( Several possible departure points ) Chapareillan , St Baldoph, Barberaz... among others.
On the practical side, the Bois Plan car park on the outskirts of Challes les Eaux is the ideal place to start, and a cycle path takes you all the way to Chambéry.

Ascension effectuée avec Éric et Dominique le 17 juillet.
Malgré la longueur et la pente pas toujours régulière c'est le versant le plus roulant pour accéder au Col du Granier.
La montée commence au Rond-Point au cœur de Chambéry, la circulation est assez dense car la D 912 traverse le massif de la Chartreuse jusqu'à St Pierre d'Entremont , village qui a la particularité d’être à cheval sur la Savoie et l'Isère.
Le bitume est correct , pas mal de zones ombragées, Pour admirer le paysage il faut se retourner car la Rte est face à la montagne, un arrêt s'impose juste avant le tunnel car au loin on peut apercevoir le Lac du Bourget.
L’Auberge au sommet du Granier n'ouvre qu'à 10h30 ce n'est pas idéal pour les cyclistes matinaux.
Ps : De nombreuses routes permettent l'accès au Col du Granier, Chambéry ( Plusieurs points de départ possibles ) Chapareillan , St Baldoph, Barberaz... entre autres.
Côté pratique le parking de Covoiturage de Bois Plan à la sortie de Challes les Eaux est l'endroit idéal pour démarrer, une piste cyclable vous amène jusqu'à Chambéry.

Nice climb on an August morning. The road isn't too bad and the passage through the tunnel is quite nice. It's a fairly easy pass.

Belle montée effectuée en un matin d'août. La route n'est pas trop mauvaise et le passage dans le tunnel plutôt sympa. C'est un col assez roulant.

Beautiful climb. Nice and steady. I did this as a warm up for the all but forgotten 1984 tour de france hors catégorie climb 'la Ruchère-en-chartreuse'.

After getting out of Chambéry I encountered maybe a dozen cars on the way up. With about 6 km to go there began the first of several sections of new smooth pavement, so that was nice. Unfortunately the restaurant at the top wasn't open so no coffee for me :)

A nice climb without much difficulty, a good warm up for an outing in the Bauges. Continue to the Col de la Cluse, which is much wilder!

Ascension sympathique sans grande difficulté.Un bon échauffement pour une sortie dans les Bauges. Continuez sur le col de la Cluse bien plus sauvage!
