Grenoble Chartreuse loop

France • Start/finish: Grenoble • Distance: 185 miles • Riding time: ±6hrs • A relaxed full-day's ride through the Chartreuse and Bauges mountains outside Grenoble. Big on epic views, light on traffic (apart from when it takes 10mins cutting across Chamberey and when it returns to the city).
NB: A Crit-Air certificate is required for riding in Grenoble.
