The "standard" way up to the Petites Roches plateau from the north of the Grésivaudan valley. The road is wide and the surface is impeccable, but the traffic can be heavy. The gradient is severe on certain sections, as far as Saint-Bernard-du-Touvet, the gateway to the plateau, and the wind can also be a spoilsport when the road is clear, so plan to use low gear ratios.

The "standard" way up to the Petites Roches plateau from the north of the Grésivaudan valley. The road is wide and the surface is impeccable, but the traffic can be heavy.

The gradient is severe on certain sections, as far as Saint-Bernard-du-Touvet, the gateway to the plateau, and the wind can also be a spoilsport when the road is clear, so plan to use low gear ratios. To compensate, there are fine views over the valley and the Belledonne mountain range almost the whole way, and once you reach the plateau you can admire the imposing eastern cliffs of the Chartreuse on your right.

Paragliding enthusiasts will find plenty to indulge their passion at Saint-Hilaire, a renowned paragliding site.

La façon « standard » de monter au plateau des Petites Roches quand on vient du nord de la vallée du Grésivaudan. La route est large, le revêtement est impeccable mais le trafic peut être important.

La pente est sévère sur certaines sections, jusqu'à Saint-Bernard-du-Touvet, porte d'entrée du plateau, et le vent peut également jouer les trouble-fêtes lorsque la route est dégagée, donc prévoir de petits braquets. En compensation, on a de belles vues sur la vallée et sur la chaîne de Belledonne quasiment tout du long, et une fois arrivé au plateau on peut admirer à loisir sur sa droite les imposantes falaises orientales de la Chartreuse.

Les amateurs de parapente trouveront de quoi assouvir leur passion à Saint-Hilaire, site de parapentisme réputé.
