From Champagne en Valromey, the most accessible route!
This ascent of the Grand Colombier (1501 m), the longest (18.5 km), is reputed to be the easiest (or least difficult!) of the four faces, with an average gradient of 5.2%, in the shade of the fir trees, for 974 m of ascent. If you want to do several climbs of the Bugiste Giant in a day, we recommend that you finish on this side.
This is the most accessible route (with an average gradient of over 6%), and offers a number of places to recover between its 10%+ ramps. The last two kilometers, however, offer no respite, with a steep slope and an often windy road. Le Grand-Colombier has to be earned!
At the summit: 360° panoramic views of the Alps, the Belledonne massif, Mont-Blanc, Bugey, the Rhône and 3 Alpine lakes (Lac du Bourget, Lac d'Annecy and Lac du Léman).
