Is the Mont Blanc Tunnel Worth It?

If you're driving between France and Italy, the Mont Blanc Tunnel is one of the easiest ways to cross the Alps. It isn't cheap, a standard car costs €55.50 one way in 2026, but the tunnel saves you from a long mountain route and provides a straightforward year-round connection between Chamonix and Courmayeur.

I crossed the tunnel myself from Italy into France, and the experience is surprisingly straightforward. Once you have paid the toll and entered the tunnel, the 11.6-kilometre journey takes only around 12–15 minutes. Before long, you're back in the Alpine landscape on the other side.
