Courmayeur is a town and comune in northern Italy, in the autonomous region of Aosta Valley. At an elevation of 1,224 m (4,016 ft) above sea level, it is located at the foot of the southern side of Mont Blanc, at 4,810 m (15,781 ft) the highest point in the Alps and western Europe (see Seven Summits), and is 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 opposite, northern, side of the Mont Blanc massif.
