Great climb, probably the calmest one in the area, traffic wise.

It is indeed Chartreuse. There is also a "must-see" that presents "a magnificent view" of Chartreuse when it is actually Belledonne!!

Personally, I don't really like going through this roundabout. Coming from St Niziers, you can turn left before, to go towards Villard.

The Brion Bridge is a suspension bridge over the Hebron River, connecting the towns of Roissard and Lavars. The bridge has only one lane.

Lans is a very pretty village in the Vercors, the resort is at Côte 2000, a little higher up. It's not necessarily the best starting point for a bike ride. We prefer Villard de Lans, which offers a multitude of routes.

It is from the road to La Corniche that we have the most beautiful views of Lake Monteynard
