The Col de l'Iseran is the highest paved mountain pass in the Alps and is situated in the department of Savoie in France near the border with Italy. It is crossed by the D902. The pass is part of the Route des Grandes Alpes and connects the valley of the Isère and the valley of the Arc River between Val-d'Isère in the north and Bonneval-sur-Arc in the south.
The Col was first used in the Tour de France in 1938 and has been used less than 10 times since then.
