Milan → Aosta → the Mont Blanc tunnel, France (A4 / A5)
The way home for most UK drivers: the A4 west and the A5 up the Aosta valley, two hours to Aosta and half an hour more to the tunnel mouth at Courmayeur, with fast charging at the valley’s service areas for the last Italian top-up. The tunnel is €55.50 one way for a car in 2026, paid by card at the booth. The same app and free card keep working through the tunnel and up through France, with the live price before you plug in at every stop.
