Col de la Forclaz from Vesonne in the Haute Savoie
Col de la Forclaz rises above the south eastern shore of Lake Annecy in the Northern Alps to an altitude of 1150m; it lies on the road between the villages of Menthon Saint Bernard to the north and Vesonne to the south.
Whichever side you climb to the col, it is steep, though climbing from this side is recognised as the more challenging due to the steeper average gradient. The climb starts immediately you leave the village where you are faced with a kilometre at over 11%! The road heads up the side of a gorge before switching back and forth steeply across alpine meadows to the village of Montmin.
After a brief descent, the last brutal 1.6km delivers you to the summit.
The Tour de France has crossed the col three times in its history, with the Tour de France 2016 crossing for a fourth time en-route to Saint Gervais les Bains.
