Starting point : Barrage du Verney

The Barrage du Verney is a dam located next to the small mountain village of Allemond.

Many cyclists also do the Alpe d’Huez, and Col du Glandon climbs on the same ride. If you’re coming from Le Bourg d’Oisans, turn left (or right if you’re descending from the Alpe d’Huez summit) onto D211B around the halfway point up Alpe d’Huez. Continue to descend towards Villard-Reculas and eventually the Barrage du Verney (Verney Dam).

The actual climb segment to Col du Glandon begins from Barrage du Verney. The climb from here is 26.3km long and averages 4.4%. The first 5km are relatively flat before the steep gradient starts to kick in. There are two short downhill sections from kilometers 11 to 13 and 22 to 24.

After 20km, you’ll arrive at the Lac de Grand’Maison. Do remember to stop and take in the breathtaking views.

Once reaching the summit, you can also continue towards Col de la Croix Fer, only 3km away.
