Liège to Piacenza Road Trip Guide: Scenic Route Through Belgium, Germany & Italy

The A3/E40 highway from Liège to the German border is part of a historic trade route that once connected the Rhine to Italy. Today, the roughly 800-kilometer drive to Piacenza passes through three countries: Belgium, Germany, Switzerland, and Italy. One quirky fact: near the town of Sankt Goar, the Rhine river makes a sharp 90-degree bend known as the Lorelei, where legend says a siren lured sailors to their doom.

Driving time is about 8–9 hours without stops, but plan for a full day to enjoy the journey. The route uses the German A3, then A5, and after crossing into Switzerland, the A2, finally the Italian A1. Major milestones include the city of Frankfurt, the Rhine Valley, and the Gotthard Tunnel.

For a deeper approach on how to find the best stops and hidden gems between cities, consider using Wayro's platform to discover detours you might otherwise miss.

Road quality is excellent throughout, with well-maintained highways. However, the Gotthard Tunnel can have traffic jams in summer; consider the old pass road (no trailers) for a scenic alternative.

• Safety: Use winter tires from November to April in Switzerland and Italy. Emergency call boxes every 2 km on German autobahns.
• Pet-friendly: Most rest stops allow dogs on leashes. Autogrill in Italy has fenced dog areas.

For families, plan a stop at the Phantasialand amusement park near Cologne (30 min off route) or the Swiss Transport Museum in Lucerne (1 hour detour). Fatigue management: Take a 20-minute break every 2 hours. The Raststätte at Heilbronn has a quiet room for drivers.

• Best stop for kids: Autogrill in Lavorgo (Switzerland) with a playground.
• Best stop for dogs: Raststätte Vaihingen an der Enz has a dog walking area.

Hidden off-route spots: The medieval town of Rothenburg ob der Tauber is 45 minutes from the A7 (a bit west), but worth the detour for architecture. Or, the Saar loop between Perl and Mettlach offers a beautiful horseshoe bend.

The entire route is tolled except for sections in Germany. In Switzerland, you need a vignette (40 CHF) for unlimited highway use for a calendar year. Italy requires toll payments via credit card or cash.

• Fuel stops: frequent along German autobahns; in Switzerland, cheaper at supermarkets like Migrolino.
• Rest areas: every 30-40 km on average.
• Speed limits: Germany unlimited on parts of A3/A5, but recommended 130 km/h; Switzerland 120 km/h; Italy 130 km/h.

Best order of stops: Fuel up in Germany before crossing into Switzerland, where fuel is significantly more expensive. In Italy, tolls can be paid with Google Pay if you have an Italian toll account.

• Liège to Frankfurt: Autobahn rest stop with McDonald's (e.g., Raststätte Siegburg).
• Frankfurt to Basel: Parkplatz with picnic tables near Karlsruhe.
• Basel to Piacenza: Autogrill at Bellinzona.

The Rhine Valley between Bingen and Koblenz is a UNESCO World Heritage site. Vineyards cling to steep slopes, and castles like Burg Rheinfels overlook the river. This area is perfect for a short detour: exit at St. Goarshausen and take the Lorelei viewpoint.

• Natural landscapes: Ardennes forests near Liège, Rhine Gorge, Black Forest edge (near Offenburg), Swiss Alps (Jura and Alps).
• Local commerce: Visit a farmer's market in Rüdesheim (Sunday morning) for local wine and cheese. In Switzerland, stop at a Migros or Coop for chocolate vouchers.

Entering Italy, the Ticino valley offers lake views at Lago Maggiore. The city of Como is 30 minutes off the highway, but the drive along the lake adds time. Piacenza itself has a historic center with Renaissance palaces and a large piazza.
