Mont Blanc is located on the border of which two countries?

Located on the border of France and Italy, Mont Blanc is the highest mountain in the Alps and Western Europe, and the highest mountain in Europe outside the Caucasus Mountains, rising 4,805.59m (15,766 ft) above sea level. It is the 2nd most prominent mountain in Europe, after Mount Elbrus, and the 11th most prominent mountain in the world.

Mont Blanc's summit lies on the watershed line between the valleys of Ferret and Veny in Italy, and the valleys of Montjoie, and Arve in France. Ownership of the summit area has long been disputed between France and Italy.

The Mont Blanc massif is popular for outdoor activities like hiking, climbing, trail running and winter sports like skiing, and snowboarding. The most popular climbing route to the summit of Mont Blanc is the Goûter Route, which typically takes two days.

The three towns and their communes which surround Mont Blanc are Courmayeur in Aosta Valley, Italy; and Saint-Gervais-les-Bains and Chamonix in Haute-Savoie, France. The latter town was the site of the first Winter Olympics. A cable car ascends and crosses the mountain range from Courmayeur to Chamonix through the Col du Géant. The 11.6 km (7+1⁄4 mi) Mont Blanc Tunnel, constructed between 1957 and 1965, runs beneath the mountain and is a major transalpine transport route.
