Thun to Krems an der Donau Road Trip Guide

The Aare River meets the Danube via a serpentine route of 780 kilometers that crosses four Swiss cantons, the entire width of Austria, and a sliver of Germany. The Thun–Krems an der Donau drive is a study in contrasts: glacial-blue lakes yield to rolling hills of the Mittelland, then the Salzkammergut's limestone peaks, and finally the gentle terraced vineyards of the Wachau. A lesser-known fact: the section between Unterach am Attersee and St. Gilgen is a 10-kilometer road that was originally a Roman salt route, now known as the L544, with gradients exceeding 12% in places.

This guide answers the questions: how long to drive Thun to Krems an der Donau? Expect 8.5 hours of pure driving, but realistic timing with stops is 10–12 hours. Is it worth driving Thun to Krems an der Donau? Absolutely — the journey itself is the destination.

Below is a quick overview of the route segments:

The A1 through Switzerland and Austria is well-maintained, with concrete barriers and lit tunnels. However, the A8 in Germany (before Salzburg) has sections without hard shoulders; stay vigilant. In Austria, the B3 is unlit and bordered by cliffs; drive slowly at dusk to avoid roe deer crossings. Winter conditions (Nov–Mar) require winter tires; chains are recommended over the Brünig Pass.

Pet-friendly framework: Most rest stops allow dogs on leads; in Austria, dogs need a muzzle on public transport. Recommended stops: Raststätte Küssnacht (Switzerland) has a dog run; in Austria, Mondsee's lakeside path is ideal. Many hotels in Krems accept pets (e.g., Hotel Klinglhuber charges €15 per night).

Family and child suitability: The entire drive is suitable for families, with frequent playgrounds at autohof (truck stops). The Voralpenexpress in Schlierbach (exit 89) has a dedicated kids' playzone. For teens, the Swarovski Kristallwelten near Innsbruck is a 20-min detour. Fatigue management: Stop every 2 hours; the Mondsee abbey park offers a serene break. Use the how to find the best stops and hidden gems between cities to plan.

Hidden off-route spots: The Griessenkareck (exit 45) leads to a tiny chapel with panoramic views of the Traunsee. The Gmundner Keramik factory outlet (15 min off A1 near Gmunden) sells painted pottery at factory prices. For a quirky stop, visit the Fahrzeugmuseum in Steyr (historic cars).

The drive is a stage for geological drama. From Thun, the Jungfrau massif dominates the rearview mirror. As you cross the Brünig Pass (1008 m), the landscape shifts to the emerald-green Lake Lungern. The Salzkammergut region around Mondsee and Attersee is a collage of alpine pastures, deep blue lakes, and traditional farmhouses where locals sell hand-carved wooden souvenirs and fresh cheese.

UNESCO World Heritage Sites: The Wachau valley (Krems to Melk) is a cultural landscape listed since 2000. Don't miss the Göttweig Abbey, baroque above the Danube. The historic center of Salzburg (Old Town) is also UNESCO. Elsewhere, the Hallstatt-Dachstein region is a World Heritage site, but the route passes within 10 km of its eastern edge.

Culinary infrastructure: Stop at a Raststätte for a Bratwurst and beer, but for better value, exit into towns. In Vöcklabruck, try the speckknödel (dumplings) at Gasthof Schwan. For wine, the Wachau offers Grüner Veltliner; visit a Heurigen (wine tavern) in Weissenkirchen. Straya Cafés in Austria serve excellent Melange coffee.

The backbone of the route is the A1/E55 motorway from Thun to just past Salzburg, then a mix of expressways and scenic B-roads. The Swiss A1 has a 120 km/h speed limit, while Austria's A1 allows 130 km/h. Toll vignettes are required: buy the Swiss vignette (CHF 40) and the Austrian one (€9.60 for 10 days). Fuel stops are abundant — every 30–40 km on motorways — but prices vary; fill up in Germany (around €1.65/L) to save compared to Switzerland (€1.80/L) and Austria (€1.70/L).

• Avoid the A1 between Bern and Zürich on Friday afternoons: congestion builds near the Wankdorf interchange.
• The B3 from Krems to Dürnstein is narrow and winding; use the S33 bypass for heavy traffic.
• Electric vehicle charging stations are available at most rest stops (e.g., Ionity and Fastned along A1).
• Currency: Swiss Francs (CHF) in Switzerland, Euros (€) in Austria. Credit cards widely accepted.
