Start your journey in Briancon, in the upper town, the walled part. Take the N91 towards the ski route of Serre-Chevalier. It has some long wide stretches and you can really open the throttle. Mountains on both sides, breathtaking. Ride over the Col du lauteret and at the jct with the D902, have a coffee break at one of the cafes to calm your nerves. Head for Bourg dOisans on the N91. Dramatic scenery. Absolute biking heaven. We rode it in July 2008. A must ride route!
