Interlaken to Tournai Road Trip: Route Guide & Hidden Gems

The road from Interlaken to Tournai crosses three countries and traverses the Jura Mountains, the Swiss Plateau, the Rhine Valley, and the rolling plains of eastern France and Belgium. This 720-kilometer journey is best driven in a single day (about 8 hours without stops) or split over two days to explore its varied attractions.
