Calm and pleasant ascent. It's uneven. You're in the shade in the forest, but there are still several viewpoints over Grenoble and as far as Chamrousse. The condition of the road is average on some sections.

Montée calme et agréable. C'est irrégulier. On est à l'ombre dans la forêt, mais il y a tout de même plusieurs points de vue sur Grenoble puis jusqu'à Chamrousse. L'état de la route est moyen sur certaines portions.

Fantastic climb that runs through the forest almost all the time, as a result it is nowhere too hot. Virtually no traffic, especially once you pass the village with the mini-descent. In the middle of the climb there is a small section that drops a bit, around this you can get some nice views of Grenoble and of the snow-capped Alpine peaks.
Although this is purely statistically tougher than the other side, it is more sheltered here. Whereas on the alternative, you cycle the entire climb in flat sun or wind.

Fantastische klim die bijna heel de tijd door het bos loopt, hierdoor is het nergens te warm. Nagenoeg geen verkeer, zeker als je het dorp met de mini-afdaling gepasseerd bent. In het midden van de klim is er een klein stukje dat even wat daalt, hierrond kan je een aantal mooie vergezichten krijgen over Grenoble en over de besneeuwde Alpentoppen.
Alhoewel deze puur statistisch zwaarder is dan de andere kant, is het hier wel meer beschut. Terwijl je bij het alternatief de gehele klim in de vlakke zon of wind fietst.

The fort itself is unfortunately not accessible to the public and appears to be very run down. Shortly before reaching it, a sign indicates that the area is currently in danger of a landslide.

Some nice views of the Grenoble area (in the first part of the climb) and then of the Herbeys plateau, the Taillefer and the southern end of the Belledonne range.

Montée particulièrement irrégulière en effet, surtout dans sa première moitié. Ensuite, après une courte descente et un long faux-plat montant, la pente, globalement raide, n'accorde plus guère de répit jusqu'au sommet.

À noter que l'altitude finale, celle du fort (937 m) est légèrement plus élevée que celle indiquée ici (905 m). Le fort lui-même n'est malheureusement pas accessible au public et semble abandonné. Peu avant d'y arriver, un panneau indique que la zone présente actuellement un danger d'éboulement.

Quelques beaux points de vue sur l'agglomération grenobloise (dans la première partie de la montée) et ensuite sur le plateau d'Herbeys, le Taillefer et l'extrémité sud de la chaîne de Belledonne.

I had done the other side first and found it quite complicated, and here it is the next level! Fortunately the big climbs are followed by small ones to rest, otherwise you would have to do the climb only in a dancer!

J'avais fait l'autre versant en premier et j'avais trouvé que c'était bien compliqué, et bien ici c'est le next level ! Heureusement que les gros pourcentages sont suivis par des petits pour se reposer, sinon il faudrait faire l'ascension qu'en danseuse !
