Quaix-en-Chartreuse Hairpins

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.

Clémencières Pass

Highlight • Mountain Pass

Highlight (Segment) • Viewpoint

Climb to the Col de Clémencière via a quiet little road with very few cars. The start is quite steep but shaded. A must-do from Grenoble.
