Description of the route

Col Dondeuil is a saddle between Becca Torché and Corno del Lago which covers Mont Crabun. Along with Col Ranzola, it was the easiest and most used road between the valleys of Ayas Gressoney. It was used for military manoeuvres in 1800 and was fortified by the Austrians; French troops crossed it on their way to battle in Ivrea. The hill offers beautiful views of the lower valley and far-off Mont Blanc.
