Bern to Tournai Road Trip: Epic Drive Through Swiss-French-Belgian Landscapes

Did you know that the A1 motorway from Bern to the French border was built on the ancient Roman road connecting Aventicum (Avenches) to Augusta Raurica? This historic artery now forms the first leg of your journey to Tournai.

This road trip covers approximately 660 km, typically taking 6 to 7 hours of pure driving time without stops. The route follows the A1 from Bern to the Swiss-French border at Basel, then the A35/E25 through Alsace, and finally the A16/E42 across Belgium to Tournai.
