This giant of a climb to 2645 metres marks the second highest col that we cover on our tours. It was first used in the Tour de France in 1911 and has been used over 30 times by the Tour de France since 1947. The climb can be tackled from the north after the Col du Télégraphe (considered the harder of the two ascents) and from the south via the Col du Lautaret where the monument to Henri Desgrange the first director of the Tour de France is located.
The steepest section on both sides is saved until the last 1km of the climb with gradients hitting am average of 12.1%. The views from the top are truly stunning.
