Brussels to Aosta Road Trip: Ultimate Guide via France & Switzerland

Did you know the Mont Blanc Tunnel, a key passage on this route, was opened in 1965 and connects France to Italy at an altitude of 1,274 meters? It is one of the longest Alpine tunnels in Europe, stretching 11.6 km.

This journey covers approximately 1,100 km via the A1/E42 highway from Brussels, then the A6/E60 through France, and finally the E25/E27 into Italy. Driving time without stops is around 10-11 hours, but we recommend at least 2-3 days to soak in the experiences.
