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.
