Kortrijk to Thun Road Trip: Best Stops & Scenic Drive Guide

The drive from Kortrijk to Thun covers roughly 550 kilometers (340 miles) and typically takes 5.5 to 6.5 hours without stops. The journey begins in Belgium's flax-weaving heartland and ends in the shadow of the Bernese Alps, passing through Luxembourg's Ardennes and the Swiss Plateau.

A little-known fact: the Belgian segment includes a stretch of the E403 where the road surface was paved with recycled glass aggregate, reducing noise by 3 decibels. This quirky detail hints at the region's blend of innovation and tradition.

Depart from Kortrijk via the E403/A17 southbound. Just past Tournai, merge onto the A8/E429 towards Brussels, then quickly divert onto the A7/E42 heading southeast toward Namur. This corridor merges with the E25 through the Luxembourg Ardennes before rejoining the A1/E25 at Luxembourg City. From there, follow the E25/E29 through Saarbrücken and Strasbourg, then switch to the A5/E35 towards Basel. Finally, take the A6/E27 from Bern to Thun.

• Total distance: ~550 km (340 mi). Expected driving time: 5.5 hours without stops.
• Tolls: No tolls in Belgium or Luxembourg. France has tolls on the A4 (around €12). Switzerland requires a vignette (€40) for highway use.
• Fuel stations: Abundant on French autoroutes, but rarer in Luxembourg's rural sections. In Switzerland, stations close early on Sundays.
• Border crossing: Schengen area, no checks.

The route transitions from the flat Flanders plains to the rolling Ardennes hills, then the Alsatian wine valleys, and finally the Swiss Alpine foothills. The most dramatic shift occurs near Colmar, where the Vosges mountains give way to the Rhine plain.

UNESCO World Heritage Sites

• Grand Place, Brussels (detour: 30 min off-route)
• Luxembourg City's fortified old town (directly on route)
• Strasbourg's Grande Île (directly on route)
• Old City of Bern (directly on route)

All four are accessible within a short detour or directly along the highway.

Local Commerce and Craftsmanship

• Bastogne: buy Ardennes ham and Trappist cheese from local producers.
• Colmar: pick up Alsatian earthenware (poterie) at the Marché de Noël (seasonal).
• Thun: visit the old town's craft shops for Swiss army knives and lace.

The cultural drift is palpable: Flemish minimalist architecture gives way to half-timbered Alsatian houses, then to the sturdy chalet style of the Bernese Oberland.
