Antwerp to Thun Road Trip: Belgium to Switzerland Guide

Did you know that the E42 highway from Antwerp to Luxembourg follows an ancient Roman road connecting the port cities of the North Sea to the Alpine passes? This route covers 620 km (385 miles) and typically takes 6.5–8 hours of pure driving time, depending on traffic around Basel and Bern.

Whether you are wondering how long to drive Antwerp to Thun or is it worth driving Antwerp to Thun, the answer lies in the diversity: from Flemish flatlands to the Jura foothills and finally the Bernese Alps. This guide answers best stops Antwerp to Thun and things to do between Antwerp and Thun.

From Antwerp, take the A1/E19 south past Brussels, then join the E411/E42 toward Luxembourg. After Luxembourg city, follow the A1 (Germany) to the A5/E35 to Karlsruhe, then the A6/E60 toward Basel. From Basel, take the A2/E25 to Bern, then the A6 to Thun. Total tolls: motorway vignette required for Switzerland (CHF 40 for 1 year). No tolls in Belgium or Luxembourg, but Germany is toll-free for cars.

• Fuel stops: Belgium cheapest (€1.60/L), Luxembourg slightly cheaper, Germany and Switzerland expensive (€1.90–2.10/L).
• Best refuel: just after crossing into Luxembourg or before entering Switzerland.
• Rest areas: every 30-40 km on German Autobahns; Swiss rest stops with picnic tables.

The route transitions from Belgian flat farmland to the rolling hills of the Ardennes, then the dense forests of Luxembourg, followed by the Rhine rift valley near Karlsruhe, and finally the Jura mountains and Alpine foothills into Thun. UNESCO World Heritage Sites along the way include the historic center of Luxembourg City (a fortress city) and the Old Town of Bern (Zytglogge and arcades). Both are worthy detours.

• Natural attractions: Müllerthal (Luxembourg) – rock formations; Rhine Falls (near Schaffhausen) – largest waterfall in Europe; Lake Thun – stunning turquoise water.
• Culinary stops: Try Flemish carbonnade (Antwerp), Luxembourgish Judd mat Gaardebounen (smoked pork), Swiss fondue in Thun.
• Local commerce: Antwerp's diamond district, Luxembourg's high-end boutiques, Bern's Zytglogge clock tower market.
