The Mont Blanc Tunnel is a 11.6-kilometer (7.2-mile) road tunnel that burrows under the Mont Blanc massif, connecting Courmayeur in Italy to Chamonix in France. Opened in 1965, it was a groundbreaking feat of engineering, cutting travel time across the Alps dramatically. Driving through the tunnel is a unique experience: the journey takes about 15 minutes, with strict safety protocols including speed limits and emergency bays. At the Italian entrance near Courmayeur, you'll see the tunnel's massive portals and can appreciate the scale of the project against the dramatic alpine backdrop. The tunnel is a lifeline for trade and tourism, carrying over a million vehicles annually. While you cannot stop inside, the approach roads offer stunning views of the surrounding peaks, and the tunnel's history as a symbol of cross-border cooperation adds to its significance.
