Col Agnel is a mountain pass in the Cottian Alps, west of Monte Viso between France and Italy which links the Queyras valley (Hautes-Alpes) with Pontechianale in the province of Cuneo, Piedmont. At 2,744 m (9,003 ft), it is the third highest paved road pass of the Alps, after Stelvio Pass and Col de l'Iseran. Despite being the highest international pass of the Alps, Col Agnel is somewhat unknown and not heavily used.
From Château-Queyras (France), the climb is 20.5 km long at an average gradient of 6.6%. From Casteldelfino (Italy), the climb is 22.4 km long at an average gradient of 6.5%.
