Quite an easy climb, however the terminal was missing due to work at the summit on the day of my ascent (mid-August 2024), hoping to return soon!

This is the classic southern slope of the pass, which begins at La Chambre. With a vertical drop of 1,591 m, a length of 19.3 km, and an average gradient of 7.9%, it's a colossus. The initial section has many hairpin bends and is covered with trees and vegetation. The intermediate section is probably the toughest. From the Saint François Longchamp ski resort, where there is a gentler section, there are a beautiful 5 km of completely open terrain where you can see the entire final section. Descending this pass is a delight because you build up speed and it also has all kinds of curves.

On its southeast side, from Epierre, it is a beautiful port. The vast majority is covered by trees, which do not allow great views of the valley; However, the road is very winding, with continuous curves that make it very bearable. It is an area to enjoy cycling since there is hardly any traffic.

The Col du Grand Cucheron from La Corbière is 11.6 kilometers long with a total elevation gain of 805 meters. The average slope is 6.94% with maximum slopes of 13.1%. A good climb to do during the summer months as there is quite a bit of shade.
