Würzburg to Davos Road Trip: Timeless Routes & Hidden Gems

Did you know that the Würzburg–Davos route roughly follows the 10° East meridian? The path descends from the Main River valley (177 m above sea level) to the 1,560 m high Flüela Pass before dropping into Davos. The drive spans about 480 km of two-lane roads and motorways, crossing three countries. It typically takes 5.5 to 6 hours without extended stops, but the real reward lies in the detours.

The route passes through Bavaria, Austria (Vorarlberg and Tyrol), and Switzerland (Graubünden). The backbone consists of the A3 from Würzburg to Ulm, the A96 through Memmingen to Lindau, the A14/E43 along Lake Constance to St. Margrethen, and then the A13 to Chur. The final 80 km from Chur to Davos wind through the Plessur Alps via the A13/E43 and the H28 up the Flüela Pass. The most time-consuming stretch is the narrow, curvy road over the Flüela, which can feel like a separate adventure.

Fueling up is straightforward, but price differences matter. Petrol in Germany is about 1.85 EUR/L, in Austria 1.75 EUR/L, and in Switzerland 2.00 EUR/L. Fill up in Austria to save money before entering Switzerland. Tolls: Swiss motorway requires a vignette (40 CHF for 14 months), while Austrian sections (A96/A14) are toll-free for now but the A14 through Vorarlberg requires a separate vignette (9.90 EUR for 10 days). Buy both at border shops or online.

• Best fuel stop: the Aral station at the A96 exit in Leutkirch (cheap diesel).
• Rest zones with panoramic views: Raststätte Aitrach (A3 near Memmingen) overlooks the Allgäu Alps.
• Crash barrier quality: High on A3/A96 (concrete median), moderate on A13 (metal guardrails), low on H28 (no barrier on most curves).
• For current road conditions: check how to find the best stops and hidden gems between cities.

The transition from Würzburg's vineyard-covered hills to the Allgäu's green meadows and then to the rugged Swiss Alps is a feast for the eyes. The A3 cuts through the Tauber River valley, offering glimpses of medieval castles like Weikersheim. Once past Memmingen, the view opens to the Allgäu Alps, with cows dotting the hillsides. The A14 passes the eastern shore of Lake Constance (Bodensee)—look for the island of Lindau with its lighthouse a few hundred meters from the road.

• Natural landmarks: the 150-m-high Bregenz cliffs just before the Austrian border; the Rhine Gorge (Ruinaulta) near Ilanz, a canyon with white limestone cliffs.
• Local commerce: stop at Bauernladen (farm shops) in the Allgäu for cheese and cured meats; in Davos, visit the weekly market (Wednesdays) for Bündnerfleisch and Engadiner Nusstorte.
• Unique culture: the Romansh minority lives in the mountain valleys around Davos; listen to the Romansh language on local radio.

Safety on this route varies. The German motorways are smooth, but the H28 from Chur to Davos has many hairpin bends with 180-degree turns, sharp inclines (up to 13% grade), and no guardrails in sections. In winter, snow chains or winter tires are mandatory on the Flüela Pass (usually closed November to May). The A96 near Memmingen often has heavy fog in autumn—reduce speed to 80 km/h.

• Fatigue management: stop every 2 hours. Ideal rest stops: Raststätte Illertal (A3, clean restrooms and a playground), Raststätte Widdum (A96, dog walking area), and the Bim Alpsee viewpoint (near Immenstadt, off the A7).
• Family suitability: the route is child-friendly if you plan stops. Playgrounds at Autobahn gas stations; a must-stop is the Legoland Discovery Centre in Ulm (exit A3). In Davos, the Alpinum Schatzalp has a children's adventure trail.
• Pet-friendly framework: most rest stops allow dogs on leash; the ferry from St. Margrethen to Konstanz (if detour) accepts pets for free. In Davos, many hotels welcome dogs—ask at the Tourism Office for a list.
• Hidden off-route spots: 15 minutes off the A3 is the ruined castle of Teck (Burg Teck) near Kirchheim—offers a panoramic view of the Swabian Alb. Or visit the waterfall at Mümliswil (near Chur) for a short hike.
