The road surface is bumpy on the steepest 3 km, but perfectly passable on a road bike. You just need to be careful on the way down. Magnificent views of the surrounding peaks (Dent de Crolles, Chamechaude, Pinéa, Grande Sure...) shortly before the end of the climb.

Beautiful views on the way up, to avoid the cars I advise you to arrive at the summit at 10 am, the surface is average, but careful on the way down, but it has improved considerably over the years.

Très belle vue durant la montée , pour éviter les voitures je vous conseille d’arriver au sommet avec 10h, le revêtement et moyen attention en descente, mais quand même en nette amélioration au fil des années.

From the Col de Porte, the climb begins with a short descent, a flat area and then, bim, a steep wall with this bumpy road, which doesn't help. You then pass over a small corbel, then finally the little hairpins, which although steep offer a mini-repair if you take them on the outside. One last slope and you leave the forest at the oratory, on the ridge between the two slopes. After that, it's easy compared to what we've just climbed. We have the Charmant Som and the alpine chalet in our sights.
The views are magnificent in this open area, with Chamechaude opposite and Le Pinéa on the ridge.
The descent isn't pleasant because of the bumpy terrain. The levers are a little tight.

Depuis le col de Porte, l'ascension commence par une courte descente, un replat et bim, un mur bien bien raide avec cette route bosselée, ce qui n'aide pas. On passe ensuite sur un petit encorbellement, puis enfin les petites épingles à cheveux, qui bien que raides offrent un mini-répit en les prenant à l'extérieur. Encore une dernière pente et on sort de la forêt au niveau de l'oratoire, sur la crête entre les deux versants. Ensuite, c'est facile par rapport à ce qu'on vient de monter. On a le Charmant Som et le chalet d'alpage en ligne de mire.
Vues magnifiques dans cette zone dégagée, sur Chamechaude en face, et le Pinéa dans la ligne de la crête.
La descente n'est pas agréable du fait du bosselage. On reste un peu crispé sur les manettes.

The road surface is bumpy on the steepest 3 km, but perfectly passable on a road bike. You just need to be careful on the way down.

Magnificent views of the surrounding peaks (Dent de Crolles, Chamechaude, Pinéa, Grande Sure...) shortly before the end of the climb. Tourists who can leave their bikes at the Chalets and have brought good walking shoes with them can easily continue on foot to the summit of Charmant Som, just 200 m higher. From there, you have an even wider view of the whole massif and beyond, as well as a bird's eye view of the Grande Chartreuse monastery.

Le revêtement de la route est bosselé sur les 3 km les plus pentus, mais tout à fait praticable en vélo de route. Il faut juste être prudent lors de la redescente.

Magnifiques points de vue peu avant la fin de la montée sur les sommets environnants (Dent de Crolles, Chamechaude, Pinéa, Grande Sure…). Pour le touriste qui peut laisser son vélo aux Chalets et a emmené avec lui de bonnes chaussures de marche, il y a possibilité de poursuivre à pied facilement jusqu'au sommet du Charmant Som, à peine 200 m plus haut. De là-haut, on a une vue encore plus étendue sur tout le massif et plus loin encore, et également une vue plongeante sur le monastère de la Grande Chartreuse.

Very short ascent with 3 complicated km: the goal of the game is to stay as long as possible in a dancer!

Ascension très courte avec 3 km compliqués : le but du jeu c'est de rester le plus longtemps en danseuse !
