Lacets de Quaix-en-Chartreuse

Highlight (Segment) • Climb

Climb to Quaix-en-Chartreuse from Saint-Égrève via a quiet road with some magnificent bends. It has a touch of Alpe d'Huez with its 21 bends, but with fewer crowds.

Col de Clémencières

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!
