Liège to Mulhouse Road Trip Guide: Best Stops & Hidden Gems

The A36/E25 corridor from Liège to Mulhouse traverses 480 kilometers of Ardennes forests, wine terraces, and industrial heritage. At the 180-kilometer mark near Luxembourg, the road crosses the Moselle valley at precisely 49°39'N, 6°09'E—a point where Celtic tribes once traded salt.

This route challenges drivers with sudden altitude changes: from 200 meters in Liège to 500 meters in the Vosges foothills. Knowing how long to drive Liège to Mulhouse is essential: expect 4.5 hours without stops, but a full day with breaks. Is it worth driving Liège to Mulhouse? Absolutely, for the cultural density of six UNESCO World Heritage Sites within a 50-kilometer radius.

Hidden off-route gem: the medieval village of Rodemack (15 km from exit 38), called 'Petite Carcassonne'. Also, the Citadelle of Bitche (Fortified town) offers underground galleries.
