Breathtaking view at the top of the Somnoz pass.
Watch out for the weather, I experienced clouds and fog at the pass while the weather was fine in Annecy.

Col du Semnoz summit

Highlight • Summit

Alas sign absent during my visit. Very nice shaded climb from Annecy as you cross state forests. Only the last two kilometers are in full sun.

Climbing Semnoz by bike is an unforgettable experience. The views are well worth the effort.

The slope through Leschaux to Mont Semnoiz is the most accessible of the 3 ascents. But first you must have already climbed the Col de Leschaux (alt. 897 m). It is 12 km at 3.5% from Sévrier to the north or 7.2 km at 4.5% from the Detrier bridge to the south.
So from the Col de Leschaux, it has 13.5 km of ascent at 6%, the maximum slope will be 9% in 1.2 km, but be careful, the distance between each hairpin will seem very long. The final will be quite easy with the last 700 meters at 4.5%.
