Courmayeur is a town and comune in northern Italy, in the autonomous region of Aosta Valley. At an elevation of  above sea level, it is located at the foot of Mont Blanc, at the highest point in the Alps and western Europe (see Seven Summits), in the Graian Alps range and crossed by the Dora Baltea. Courmayeur shares administration of Mont Blanc with its neighboring commune of Saint-Gervais-les-Bains in France, and is consequently able to claim the title of highest commune in Italy. Courmayeur also shares access to the famous glacial ski run of the Vallée Blanche with another French town, Chamonix, which sits at the other side of the peak known as the Aiguille du Midi.
