Hard road ride. Very good fitness required. Mostly well-paved surfaces and easy to ride. The starting point of the route is accessible with public transport.

View of Lake Annecy from Semnoz

Highlight • Viewpoint

Super fun descent!! Really long and the road is really swoopy and fun. Completely worth the climb up. Plus view of Annecy lake in a lay-by!

A long climb from Saint-Jorioz to the summit of the Montée du Semnoz. But definitely worth it. There's a mountain hut at the top.

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.

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.
