Dijon to Aachen: Ultimate Road Trip Guide

The A31 motorway from Dijon to the German border follows the ancient Roman road Agrippa, connecting the Rhône valley to the Rhine. You will cover 480 kilometers in around 4.5 hours without stops, but the journey deserves attention. The route passes through three countries—France, Luxembourg, and Belgium—each with distinct road signage and fuel pricing. Key highways: A31 (France), E25/E411 (Luxembourg-Belgium), and A4 (Belgium to Aachen).

From Dijon, the A31 climbs gently through the Burgundy vineyards (Côte de Nuits) before descending into the Langres Plateau. The landscape then flattens into the Lorraine plain near Nancy. After the Luxembourg border, the Ardennes forest begins—rolling hills covered in beech and oak. The stretch from Luxembourg to Aachen passes through the Our valley, a deep river cut. Sunset views are best near the Moselle river, just south of Luxembourg City. The region is also known for its morning fog in autumn, reducing visibility.

• UNESCO sites: Notre-Dame Cathedral of Luxembourg (detour 5 min from city center) and the Roman monuments of Trier (30 min detour off A1).
• Geographical shift: from wine country to dense forests.
• Local delicacies: stop at 'Boulangerie du Pont' in Langres for fougasse, or 'Chocolaterie M' in Aachen for Printen.

Fuel costs vary significantly. In France, diesel averaged €1.80/L (2025); in Luxembourg, cheaper at €1.50/L; Belgium around €1.70/L. For a typical car, expect €60-80 total. The topography is mostly flat after leaving the Côte-d'Or hills, with long gentle gradients on the A31. Fuel stations are dense every 30 km in France, but rarer in Belgium after Arlon. Tolls: A31 from Dijon to the Luxembourg border costs about €20 (pay by card or cash). No tolls in Luxembourg or Belgium on this route. Night illumination is good on all motorways except small stretches near the Belgian-Luxembourg border. The A4 in Belgium has LED lighting near cities.

• Driving time: 4.5h non-stop, but plan 6-7h with breaks.
• Best fuel stop: purchase in Luxembourg before crossing into Belgium.
• Toll plazas: take ticket, pay at exit or with electronic badge.

Road surface quality is excellent on French motorways, slightly worn on Belgian sections near the border. All have hard shoulders. Safety tips: watch for speed cameras between Toul and Nancy (fixed radars). Night illumination is present on 70% of the route; bring a reflective vest and warning triangle. Toll lanes require cash or card—keep small change. Fatigue management: Plan rest at the Aire de la Voivre (km 60, near Nancy) with a dedicated nap zone and children's play area. For families, the 'Parc de la Wiltz' in Luxembourg (off exit 5) has a petting zoo. Pet-friendly: Aire de Remich has dog-walking fields. Hidden off-route: the abandoned village of Hattonville (5 min exit 21 towards Stenay) with ruins from WWI.

• Recommended nap spots: Aire de la Voivre (France), Aire de Wemperhaardt (Luxembourg).
• Family: interactive museum 'MUDAM' in Luxembourg (30 min detour).
• Pet stops: Aire de Beckerich has dedicated dog area.
