Cologne to Mulhouse Road Trip: Ultimate Guide to Hidden Gems

The A555 between Cologne and Bonn was Germany's first autobahn, opened in 1932. Today, your journey from Cologne to Mulhouse follows this pioneering route south, then merges onto the A61 and A5 before crossing into France.

How long to drive Cologne to Mulhouse? Expect about 4.5 hours of pure driving time covering roughly 450 kilometers. But is it worth driving Cologne to Mulhouse? Absolutely—the route threads through volcanic landscapes, vineyard-covered hills, and medieval towns that demand exploration.

Volcanic Eifel and Rhine Gorge

South of Cologne, the Eifel region boasts dormant volcanoes and crater lakes. The A61 cuts through this landscape, with the Laacher See as a prime example.

• Stop at Maria Laach Abbey, a 900-year-old Benedictine monastery overlooking the lake.
• Sample local wines at a Weinstube in the Ahr Valley, a side trip of 15 minutes.

Black Forest Foothills and Alsatian Wine Road

Near Karlsruhe, the Black Forest begins. The A5 parallels the Rhine, offering vineyard views. Cross into France at Strasbourg, then follow the Alsatian Wine Route to Mulhouse.

• Visit Riquewihr, a medieval gem with colorful half-timbered houses.
• Try Alsatian Choucroute and local Riesling at a winstub.
• Explore Mulhouse's Cité du Train, the largest European railway museum.

Two UNESCO sites lie near the route: the Upper Middle Rhine Valley (between Bingen and Koblenz) and Strasbourg's Grande Île.

• Rhine Valley: Drive the B9 along the river for castle views.
• Strasbourg: Park at Rotonde and walk to the cathedral.
