San Sebastián to Liège Road Trip Guide: The Ultimate Route

Did you know that the A63 highway near Biarritz was once a Roman road called the Via Aquitania? This ancient path connecting the Atlantic to the Mediterranean is now part of your route from San Sebastián to Liège. You'll cover approximately 1,200 km (745 miles) in about 11-12 hours of pure driving, but with stops, plan for two full days. The journey crosses three countries: Spain, France, and Belgium, each with distinct road quirks. French tolls are unavoidable; expect to pay around €80-100 in tolls alone for a standard car.
