ITINERARY
From Bourg d'Oisans, head towards Alpe d'Huez. Enjoy a short, flat kilometer before tackling the famous climb.
From La Garde en Oisans (turn 16), the route becomes fully signposted with "Isère à vélo n°1" signs.
When you reach Alpe d'Huez, follow the signs for "Office de Tourisme" then "Quartier Bergers". Pass the altiport and follow the "route du col de Sarenne".
Cross the pass and descend into the Ferrand valley. Make your way to the village of Clavans le Bas and then Mizöen. At the end of a steep descent, you find the D1091. Pass over the Chambon dam, then continue to Le Freney d'Oisans.
At Le Freney, shortly after the Avia service station, turn right onto the D211a and head uphill towards Auris. Follow the road to the hamlet of La Balme. Return to La Garde en Oisans via the "Route de la Roche". A narrow road punctuated by 3 tunnels, carved into the cliff face. The panorama over the plain of Bourg d'Oisans is breathtaking.
Once you reach La Garde, the D211 takes you down to Bourg d'Oisans.

VARIATION
You can take this route in the other direction, turning right at La Garde, towards Auris en Oisans on the D211a. In this direction, you'll only climb a third of the 21 mythical bends to Alpe d'Huez (at the end of the route, you'll do the whole thing downhill), but the ascent of the balcons d'Auris and the ascent of the Col de Sarenne from Mizoën are just as interesting!

ANECDOTE
On July 18, 2013, Le Tour de France, signed a piece of bravery for the riders of the Tour de France.
The brand-new route takes in the Alpe d'Huez climb twice: 21 + 21 = 42 bends! A first ascent, a descent via the Col de Sarenne to Bourg d'Oisans, to finish the bill with a second 21-turn ration...
