Brussels to Boulogne-sur-Mer Road Trip Guide: Best Stops

The A10/E403 motorway from Brussels to Boulogne-sur-Mer covers about 220 km, typically taking 2.5 to 3 hours of driving time. A little-known detail: the route crosses the historic Ypres Salient battlefields, and near the French border, you'll drive along a section of the ancient Roman road Via Agrippa. This drive offers a shift from urban Belgian flats to rolling Picardy hills and finally the Opal Coast.
