Valdigne

The Valdigne is the upper part of the Aosta Valley in north-west Italy. It is traversed by the Dora Baltea (), a tributary of the Po.
It extends from Derby (a "frazione" of La Salle) to Courmayeur, including the side valleys of Val Ferret, Val Veny and La Thuile Valley.
The communes which belong to the Valdigne are Courmayeur, La Salle, La Thuile, Morgex and Pré-Saint-Didier: together they make up the municipal union the Unité des communes valdôtaines du Valdigne - Mont-Blanc.
