THAT LITTLE BIT FURTHER: Col de Parquetout
If you’re brave enough to continue up to the Col de Parquetout, the ride gets a lot tougher! Even though the climb is relatively short, there’s no let up. It is one of the toughest passes in Isère!
The maximum gradient is 16%, the average 10% and the minimum 9%... it sets the tone.
Ride down from the Col d’Ornon towards La Mure. Cross through Chantelouve and Entraigues. At kilometre number 16, leave the D526, turning left just before the bridge (clearly visible, with its wooden structure) leading to Valbonnais. You then have a 7 km ride up the D212f before reaching the col.
