The natural amphitheatre of the Mont Blanc chains forms a splendid backdrop to Courmayeur, and boasts the highest mountain peak in Europe, at an altitude of 4810 m. The summit of Mont Blanc was first conquered in 1786, but it remains to this day one of the greatest challenges for climbers from all over the world.

Its imposing face overlooks all the municipalities of the valley bottom, which include La Salle , Morgex , Pré-Saint-Didier and Courmayeur , which together with La Thuile make up the "Valdigne" . At the foot of the mountain chain, two especially attractive valleys open out: the Val Veny , which runs along the side of the Brenva Glacier and presents a narrow, wild, forbidding mouth that widens out into a flat basin, and the relaxing, gentle Val Ferret with its splendid views.

At Pré-Saint-Didier lies the opening to the valley of La Thuile, which reaches right to the Little Saint Bernard Pass , the area the Romans called Alpis Graia and which since ancient times has been the main communication route through the Alps into France. The Pass retains traces of its ancient history to this day and is a pleasant, feasible alternative to the Mont Blanc Tunnel for those wishing to venture into France during the summer.
