The best reason to bike to the Pré de Madame Carle are the final 5 kilometers after the passage of Ailefroide. A largely steep (~10%) and narrow road climbs up a superbly beautiful valley. The forest here is sparse enough to enable views on the surroundings mountains, the verge of the road is full of purple flowers and towards the end of the tour Glacier Blanc can be seen (in 2013!). Unfortunately for cyclists this glacier is, on sunny summer days, the aim for many tourists with their cars. The tour starts at the bridge over the Durance in l'Argentière-la-Bessée and follows the busy D994e until Vallouise. Biking becomes nicer after Vallouise when several villages skirt the road. After driving through a short tunnel true climbing begins with a 2 kilometer long section of moderate steepness (8%) followed by an easier part until Ailefroide. The most beautiful and challenging part then completes the climb.
