THE “LITTLE EXTRA”: Parquetout Pass
If you are brave enough to go to the Col de Parquetout, the atmosphere changes radically! Although this climb is short, it will give you no respite. It is one of the hardest passes in Isère!
Max. slope 16%, average slope 10%, min. slope 9%… that sets the tone.
Since col d’Ornon, descend towards La Mure. Cross Chantelouve and Entraigues. At the 16th kilometer, leave the D526 by turning left just before the bridge that leads to Valbonnais, clearly visible with its wooden frame. You have 7 km left to drive on the D212f before the pass.
