This fairly easy road through the Lignarre Valley is very popular among cyclists at the beginning of the season. The bravest cyclists will use this warming up to carry on to the Valbonnais side up to Col de Parquetout, one of the toughest in the region.

ITINERARY
From Bourg d’Oisans, follow the D1091 towards Grenoble. After the second kilometre turn left and follow the D526 towards Valbonnais - la Mure - Ornon. You will reach Col d'Ornon after 14 km. The last few kilometres before you reach Col dOrnon are a little more challenging than the rest of the itinerary, but are never too exhausting.
At the pass, you can take a break at the chalets and the restaurants at the ski resort of Col d'Ornon.
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.
