The mountain lies in a range called the Graian Alps, between the regions of Aosta Valley, Italy, and Haute-Savoie, France. The location of the summit is on the watershed line between the valleys of Ferret and Veny in Italy and the Arve Valley in France.
The two most famous towns near Mont Blanc are Courmayeur in Aosta Valley, Italy, and Chamonix in Haute-Savoie, France—the site of the first Winter Olympics. A cable car ascends and crosses the mountain from Courmayeur to Chamonix.
The Mont Blanc massif is popular for mountaineering, hiking, skiing and snowboarding.
