Grand Colombier

The Grand Colombier, one of the hardest climb of the Tour de France

Memorable climb of the Tour de France in the 2012, 2016 and 2017 editions and final ascent of 2020 edition 15th stage of the Tour de France, every cyclist that has been to the top agrees that the Grand Colombier is one of the hardest climb in France, harder than Alpes D’Huez and comparable to Mont Ventoux. Climbing it is a real challenge for cyclists with 18 km from Culoz, 1262 m of elevation and several parts at 14%.

Located 30 min away from Aix-Les-Bains, 1h from Geneva and Annecy, 1h30 from Lyon, there are 4 different ways to reach the top of this Hors catégorie climb. The most iconic road starts from Culoz, with its famous hairpins and the most difficult road starts from Artemare through Virieu-le-Petit with slope of 22% at its steepest, and 19% during 3 km.
