Meadows Pass

Highlight • Mountain Pass

Route taken from Thoiry (from the Marocaz pass). The neck is fairly regular (7 to 8.5% of memory) but the finish is much flatter.

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.
