Boulogne-sur-Mer to Ulm: A Grand Road Trip Through Europe's Heart

On June 6, 1944, the first Allied troops landed on the beaches near Boulogne-sur-Mer—today, you can drive from that historic coast to the Danube city of Ulm in about 7 hours (via A16, A26, A5, and A8). This route crosses three countries and countless landscapes, from the Opal Coast to the Swabian Alps.

Your drive begins on the windswept Opal Coast, with chalk cliffs and lighthouse views. Rolling hills of Picardy give way to the Champagne plains, then to the wooded Vosges foothills. Crossing into Germany, the landscape opens into the Swabian Jura, with limestone plateaus leading to Ulm.

• Local commerce: Buy Maroilles cheese in Picardy (roadside farm shops near A26 exit 5), Champagne bottles direct from growers in Épernay (detour 10 km), Swabian Maultaschen (dumplings) in Ulm market.

The journey from Boulogne-sur-Mer to Ulm is a mix of French autoroutes and German autobahns. The A16 from Boulogne to Calais merges into the A26, which continues past Reims and into the Grand Est region. Near Strasbourg, cross into Germany on the A5, then follow the A8 to Ulm.
