Dinant to Metz Road Trip: A Complete Guide to the Route

The A4/E25 highway connecting Dinant (50.2607° N, 4.9134° E) to Metz (49.1193° N, 6.1757° E) covers approximately 140 kilometers, with a driving time of about 1 hour 45 minutes without stops. The route follows the Meuse River valley south from Dinant, crosses into Luxembourg, then descends through the Lorraine plateau into Metz. It is worth driving Dinant to Metz for the scenic transitions: from the steep cliffs of the Belgian Ardennes to the flat, fertile farmland of northeastern France.

On the A4/E25, you'll encounter the border crossing at Schengen (Luxembourg), where the road becomes the A31. The stretch between Luxembourg city and Metz is known for its long, straight sections, making it easy to make good time. However, the best stops Dinant to Metz are often just off the highway—like the medieval town of Thionville or the reservoirs of the Lorraine countryside.
