The 7 km of hairpin bends are quite strenuous, but the uphill ride remains pleasant on this small and little-used road. There is a somewhat Mediterranean feel to this south-facing, wind-sheltered slope with its covering of pine trees!

From Bourg d’Oisans follow the D1091 towards Grenoble.
After the second kilometre, turn left and follow the D526 to cycle towards “Ornon / Oulles”.
After 1.6 km turn right and take the D221 to Oulles.
At the agenda, 7 km of hairpin bends on a steep slop... until the end.
This road ends in a cul-de-sac, so you will cycle the same route to go back.
It was not until 1963 that Oulles, the smallest municipality of Isère, became accessible to vehicles with the excavation of its first proper road cut straight through the rock. The little mountain village facing the La Meije and the Ecrins mountains had therefore remained relatively cut off from the world until only recently, and has preserved all its charm.
In the Middle Ages there were also silver mines.
From 05/01 to 10/31 : open daily.
