Passage des Barres above La Balme à Collomb

Highlight • Other

Superb but very steep if you take it on the descent. People sensitive to heights should abstain. The same goes for the pas des barres on the descent on the other Granier route or if you do a loop.

Located at an altitude of 1,933 meters to the north of the Chartreuse massif, Mont Granier offers many exceptional panoramas. From the summit you can see the Grésivaudan plain, the Combe de Savoie, the Belledonne massif as well as Lake Bourget.

La Balme Cave in Collomb

Highlight • Cave

Magnificent viewpoint, both at the top and at the bottom. Some technical sections favor hiking rather than trail running. You'll find ibexes (and their babies), chamois, and marmots at the summit. This is one of the trails worthy of a Windows wallpaper! 👌
If you do a full tour, there are some sections that are close to climbing, so be warned. However, it's possible to turn around everywhere, with plenty of side sections, so there are always solutions! 😁
