Highlight • Viewpoint

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.

Crêt de Châtillon Summit

Highlight • Summit

Le Crêt de Chatillon is the highest point in Semnoz, at an altitude of 1,702 m. The panorama is exceptional! We have a 360 ° view of Mont Blanc, the Aravis chain, the Bauges, the Beaufortain and the Belledonne chain. We also see Lake Annecy, that of Bourget, and even a part of Lake Geneva!
