Konstanz to Kortrijk: The Ultimate Road Trip Guide

The 700-kilometer journey from Konstanz on Lake Constance to Kortrijk in Belgium crosses four countries and two major European watersheds. The route typically follows the A81 north to Stuttgart, then the A5 and A3 through Frankfurt and Cologne, before joining the Belgian A19. A little-known fact: the stretch through the Black Forest includes sections where the road gradient exceeds 6%, requiring lower gears for efficient driving. This guide will help you navigate the journey, answering is it worth driving Konstanz to Kortrijk with a resounding yes—if you plan for the right stops.

German autobahns have excellent surface quality but high speeds; use the right lane unless overtaking. Belgian roads may have cobblestones in town centers; slow down to avoid damage. No toll gates in Germany; Belgian motorways are toll-free except for a few tunnels (€2–5). Night illumination is standard except on rural A-roads. For fatigue management, rest areas (Raststätte) appear every 50 km in Germany; recommended stops: Sindelfingen (A81), Rüsselsheim (A67), and Barchon (A3 in Belgium). For families and child suitability, the Nürburgring (A48, exit 32) offers a family-friendly motor museum and go-kart track. Pet-friendly framework: many Raststätten have designated dog walking areas; the Frankfurt Flughafen rest stop includes a pet relief zone. Hidden off-route spots: the abandoned St. Nicholas Church in Reutlingen (A81, exit 14) and the miniature village of Logne (A26, exit 9) are oddities worth a 5-minute detour.

The geography shifts dramatically from Alpine foothills to the Rhine Valley and the Ardennes. South of Stuttgart, the Black Forest offers thick pine forests and winding roads. Near the Rhine, the landscape opens into vineyard-covered hills—the Nahe region produces excellent Rieslings sold at roadside Weingüter. Past Cologne, the land flattens into the Belgian lowlands, where the Scheldt valley stretches to Kortrijk. For an authentic taste, stop at a Belgian friterie near the border for frites with andalouse sauce. Things to do between Konstanz and Kortrijk include the German Christmas markets in Stuttgart (seasonal) and the Belgian town of Tournai with its UNESCO-listed cathedral.

• UNESCO sites on route or within 30-min detour: Speyer Cathedral (A61, exit 61), Cologne Cathedral (A3, exit 8), Tournai Cathedral (A8, exit 34).
• Local specialties: Black Forest ham, Nahe wine, Belgian chocolate and beer.
