Davos to Krems an der Donau: Alpine to Danube Road Trip

This route from Davos (1,560 m) to Krems an der Donau (203 m) descends over 1,350 meters, crossing three major Alpine passes and the Danube River. The most direct path uses the A13/E43 through Liechtenstein, then A1/E60 via Bregenz to Ulm, and finally A3/E56 east to Krems. Total driving time without stops is approximately 6.5 hours, but plan for 8-9 hours with breaks.

Fact: The last 30 km into Krems pass through the UNESCO Wachau Valley, a stretch of the Danube known for its terraced vineyards and medieval castles. For tips on how to find the best stops and hidden gems between cities, refer to Wayro's guide.

Infrastructure Safety & Road Quality

• Swiss A13: mostly good condition but narrow tunnels (e.g., Gotschna tunnel) and steep grades (max 7%). Use low gear to save brakes.
• German A7: excellent surface, but frequent construction zones (max 80 km/h). Pay attention to temporary lane markings.
• Austrian A3: well-maintained, but some sections near Krems are two-lane undivided; overtaking is restricted.
• Night driving: The route is well-illuminated near cities, but dark in rural stretches. Headlights on in all tunnels (even in daytime).
• Safety tip: Carry a warning triangle and first aid kit (mandatory in all three countries).

Family and Child Suitability

• Swiss Transport Museum in Lucerne (1h detour) – large interactive museum, but not directly en route.
• Lake Constance Promenade in Bregenz – family-friendly walk, playgrounds, and a gondola ride up the Pfänder mountain (great view).
• Legoland Deutschland in Günzburg (5 min off A8 near Ulm) – perfect for children aged 2-12. Allow 4-5 hours.
• Wachau Valley Railway – a heritage train runs from Krems to Emmersdorf; kids love the steam locomotives.

Pet-Friendly Framework

• Dogs are allowed on most rest stops if leashed. Attent to dog waste.
• Pet-friendly cafes: In Bregenz, Café Spitz has water bowls; in Ulm, Café Lieb is dog-welcome.
• Walks: At Rastplatz Allgäu (A7 near Leutkirch) – a large grassy area with dog stations. In the Wachau, the river banks near Dürnstein are ideal for a short walk.

Fatigue Management & Rest Zones

• Recommended rest stop 1: Raststätte Wiesensteig (A8 near Ulm) – modern, clean, with a quiet zone for a 15-min nap. Parking is free for 2 hours.
• Recommended rest stop 2: Rastplatz Grünten (A7 near Altenstadt) – a scenic lookout point with benches; ideal for a short break.
• Emergency nap spots: Off the A3, there are unofficial forest pull-offs near Passau. Look for Parkplatz Altwörth – safe, flat, and quiet.
• Tool: Use Wayro's app to find rest stops that are hidden gems for a power nap.

Hidden Off-Route Spots

• Liechtenstein Castle (Burg Liechtenstein) near Nüziders (5 min off A14) – a small, restored medieval castle with a museum. Free entry to the courtyard.
• Burg Hohenneuffen (10 min off A8 near Bad Urach) – a large ruin with a panoramic view of the Swabian Alb. Admission €3, worth the detour.
• Ruine Hartenfels (10 min from A3 near Tiefenbach) – a forgotten castle ruin overlooking the Danube. Free, few tourists. Park at the village church and walk 300 m uphill.
• Marsbach Castle (5 min from A3 near Hofkirchen) – a 12th-century fortress now a hotel, but you can view the exterior and garden for free. Great photo spot.

Culinary Infrastructure

• Bergrestaurant Gotschnablick (Davos area, CH) – authentic Swiss cuisine, cheese fondue, and panoramic views.
• Gasthof Löwen in Vaduz (LI) – Liechtenstein's oldest inn, serving Käsknöpfle and local wine. Exit A13 at Vaduz.
• Raststätte Ulm/Elchingen (DE) – modern highway rest stop with a food court offering regional Swabian dishes (Maultaschen, Spätzle).
• Gasthaus Wilder Mann in Passau (DE) – traditional Bavarian cuisine, near the A3 exit. Try the Schweinshaxe (pork knuckle).
• Restaurant Klinglhuber in Krems (AT) – riverside terrace, seasonal local food. Reservations recommended.

Road types: The route includes Swiss motorways (vignette required), German autobahns (partly toll-free), and Austrian expressways (vignette required). The A13 in Switzerland has steep gradients and tunnels. German A7 and A8 have speed limits (130 km/h) and construction zones. Austrian A1 has rest stops every 20 km.

Toll vignettes: Switzerland requires an annual vignette (CHF 40) for motorways; daily vignettes are not available. Austria requires a vignette for 10 days (€9.90) or 2 months (€14.50). You can buy them at border petrol stations or online. German autobahns are toll-free for cars.

Fuel and Route Economics

• Total distance: ~500 km. Fuel cost: approx. €70-90 (petrol) depending on vehicle. Diesel is cheaper by ~10%.
• Fuel stations are abundant along the Swiss A13 and German A7, but rare between Ulm and Krems on the A3; fill up in Ulm.
• Fuel efficiency tip: Cruise control at 110-120 km/h reduces consumption by 15% compared to 140 km/h.
• Average price per liter (95 octane): Switzerland ~€1.70, Germany ~€1.60, Austria ~€1.50.

Parking in Krems: Several paid parking garages (e.g., Parkhaus Krems, €3/h) and free lots at the edge of the old town (e.g., P5).

Geographical shifts: Start in the high Alps of Davos (pine forests, rocky peaks). Descend through the Prättigau valley to the Rhine valley. Near Bregenz, the landscape flattens to Lake Constance (Bodensee). North of Ulm, the terrain turns into rolling hills of the Swabian Jura. Finally, enter the Danube valley near Regensburg, with wide plains and the river's sweeping bends.

UNESCO World Heritage Sites

• Wachau Cultural Landscape (short detour at the end of the route): This 30 km stretch of the Danube between Melk and Krems is a UNESCO site. Highlights: Melk Abbey, Dürnstein castle, terraced vineyards.
• Old Town of Regensburg (20 km detour from A3): A well-preserved medieval city with the Stone Bridge and cathedral. Worth a 2-hour stop.
• Prehistoric Pile Dwellings around the Alps (near Lake Constance, e.g., Unteruhldingen). Not directly on route but a 15-min detour from Bregenz.

Local Commerce & Culture

• In the Prättigau (Switzerland), look for roadside stands selling Bündner Nusstorte (nut cake) and Bündnerfleisch (air-dried beef).
• In the Bregenz area (Austria), try Käsknöpfle (cheese noodles) at a traditional Gasthof.
• Near Ulm (Germany), buy Ulm Spatz (pasta) and local beer from area breweries.
• In the Wachau valley, purchase Marillenschnaps (apricot brandy) and white wines (Grüner Veltliner).

Climatic Conditions & Route Aesthetics

• Davos is often cool (15-25°C summer), while Krems can reach 30°C. Expect temperature rise of 1°C per 100 m descent.
• The A13 through the Rhine valley can be windy (sidewinds) especially near Lake Constance. Crosswinds are strongest between Bregenz and Lindau.
• Sunset from the Danube near Krems is spectacular – the sun sets over the river, illuminating the vineyards. Best viewpoint: ruins of Hinterhaus above Spitz.
• For autumn drives, the vibrant foliage in the Wachau is best in October. Spring brings blooming apricot trees.
