London to Durbuy Road Trip Guide: Best Stops & Tips

The drive from London to Durbuy, the world's smallest city in Belgium's Ardennes, covers roughly 350 miles (563 km) and takes about 5.5 to 6 hours excluding stops.

Departing London, take the M20 motorway southeast to Folkestone for the Eurotunnel Le Shuttle (35-minute crossing) or Dover for ferries to Calais (1.5 hours). The Eurotunnel is faster and more reliable, especially in bad weather. Upon arrival in Calais, join the A16 motorway towards Dunkirk, then the E40 to Brussels. At Brussels, take the E411 towards Namur and Luxembourg, exiting at exit 5 for Barvaux-sur-Ourthe, then follow signs to Durbuy.

• Fuel stops: Service areas on the A16 near Saint-Omer, E40 near Ghent, and E411 near Namur offer competitive fuel prices. Belgian motorway fuel is cheaper than UK but avoid French A16 toll road fuel stations which are pricier.
• Tolls: The UK section is toll-free except for the Dartford Crossing (free after 10pm). In France, the A16 from Calais to the Belgian border is toll-free. Belgium has no motorway tolls, but the Liefkenshoek Tunnel near Antwerp has a toll (€5-19 depending on vehicle).
• Rest areas: Every 30-50 km on Belgian motorways have well-maintained rest areas with toilets, snacks, and picnic tables. Notable ones: Aire de la Lys (France) and Raeren (Belgium) on E40.

For electric vehicles, charging stations are abundant: Ionity at Calais, Tesla Superchargers at Ghent and Brussels, and fast chargers at service areas along the E411. Plan a stop at the Brussels-Capital Region for a quick top-up.

The route transitions from England's rolling green hills (Kent Downs) to the flat plains of French Flanders, then into Belgium's undulating Ardennes.

The Ardennes region is known for its rugged beauty, ideal for hiking, kayaking, and cycling.

• Natural attractions along the way: Cap Blanc-Nez (France) offers stunning white cliffs and views of the English Channel, a 10-minute detour from the A16. Near Durbuy, the Sy Valley and the Roche aux Faucons viewpoint provide panoramic vistas.
• UNESCO World Heritage Sites: The city of Bruges is a 30-minute detour from the E40, famous for its medieval architecture. In Brussels, the Grand Place and Victor Horta buildings are UNESCO-listed. Near Durbuy, the Major Mining Sites of Wallonia (Grand-Hornu) are worth a visit.
• Local commerce: In Durbuy's town center, shops sell local specialties like Ardennes ham, cheese, and the famous Durbuy beer (Brasserie de l'Ourthe). Nearby, the Caves of Hotton offer guided tours and local wine tasting.

Hidden off-route spots include the Château de Modave (a stunning castle with guided tours) and the natural springs of Spa, both within 30 minutes of the E411. For a rural detour, the village of Clervaux (Luxembourg) is 45 minutes south of Durbuy, featuring a medieval castle and the World Press Photo exhibition.
