ROUTE
From Bourg d’Oisans, take the D1091 toward Grenoble. After 2 km, turn left toward Valbonnais–La Mure–Ornon via the D526. The Col d’Ornon is at the 14 km mark. The final kilometers before the Col d’Ornon are a bit steeper than the rest of the route, though never too grueling.
At the pass, you can stop for a break at the lodgings and restaurants in the Col d’Ornon ski resort.

THE “EXTRA BONUS”: Col de Parquetout
If you’re brave enough to make it all the way to the Col de Parquetout, the atmosphere changes dramatically! Although this climb is short, it won’t give you a moment’s respite. It’s one of the toughest passes in Isère!
Max. gradient 16%, average gradient 10%, min. gradient 9%… that sets the tone.

From the Col d’Ornon, descend toward La Mure. Pass through Chantelouve and Entraigues. At the 16th kilometer, leave the D526 by turning left just before the bridge leading to Valbonnais—easily recognizable by its wooden framework. You have 7 km left to ride on the D212f before reaching the pass.
