Highlight • Mountain Pass

One of the most accessible passes from Grenoble. There are three possible access points: via the Col de Porte road (very busy, you constantly smell diesel...), via the Clémencières road …

Clémencières Pass

Highlight • Mountain Pass

A wonderful little pass just outside Grenoble. The climb via the Narbonne road is definitely worth the detour. It's steeper than the traditional route, but so peaceful!

View of the Écoutoux Massif

Highlight • Viewpoint

The climb to Sarcenas from the Col de Clemencere towards the Col de Porte. Great view of Chartreuse, on a quiet, car-free road. The blocked road area passes without worries by bike.
