Mittenwald to Krems an der Donau: Ultimate Alpine to Danube Road Trip

This 380-kilometer drive links two of Central Europe's most charming towns: Mittenwald, famed for its painted houses and violin-making, and Krems an der Donau, a UNESCO-listed gateway to the Wachau Valley. The journey traces the Isar River south, then crosses the Austrian Alps via the Fern Pass, and descends through the Salzkammergut to the Danube Valley. A little-known fact: the route passes within 10 kilometers of the Heidentor, a 4th-century Roman triumphal arch near Petronell-Carnuntum, making this drive a timeline of Alpine and Roman history. The drive without stops takes roughly 4.5 hours, but most travelers stretch it to two days to absorb the landscapes. Use a tool like how to find the best stops and hidden gems between cities to plan your perfect itinerary.

The Fern Pass requires caution: gradients up to 14% and tight hairpins. Use engine braking and avoid overtaking on bends. For families, the 'Erlebnisbad Aquapulco' in Bad Tölz (off the A8) offers indoor pools and slides. Between Linz and Krems, the 'Danube Bicycle Trail' parallel to the highway has rest areas with playgrounds. Fatigue management: plan a stop every 2 hours. The 'Raststätte Ansfelden' on the A1 has a 24-hour service area with showers and a children's area.

• Pet-friendly: Most Austrian rest stops allow dogs on leashes. The 'Tierpark Hellabrunn' in Munich is a detour for animal lovers.
• Roadside emergency phones on A1 every 2 km.
• Hidden off-route spot: The 'Grottenbahn' in Kufstein (30 min detour) is a dragon-themed cave train for kids.

The route transitions from the limestone peaks of the Karwendel range to the rolling hills of the Bavarian Alpine Foreland, then through the Salzkammergut lake district, ending at the terraced vineyards of the Wachau Valley. In spring, the Fern Pass is flanked by wild daffodils; in autumn, the Danube valley glows with golden leaf colors. Local commerce thrives on regional specialties: Tyrolean Speck in Lermoos, Mondsee's handmade ceramics, and Wachau apricots sold at roadside stands near Spitz.

• Natural highlight: The Plansee lake (near Reutte) offers turquoise waters and a 9-km cycling path.
• Cultural stop: Stift Melk's Baroque abbey overlooks the Danube. Its library holds 1,600 manuscripts.
• Market towns: Mödling's old town has a Friday produce market with local cheeses and wines.

The drive begins on the B2 from Mittenwald to Garmisch-Partenkirchen, then merges onto the A95 toward Munich. After bypassing Munich on the A99, take the A8 east to the A93 Inntalautobahn, which leads to the Fern Pass (B179). The Fern Pass climbs to 1,210 meters and is one of the steepest grades on the route. From the pass, descend to Reutte and continue on the B179 to the A7 at Füssen. The A7 runs south to the A1 at Memmingen, but a more scenic alternative is the B17 via Landsberg am Lech. The final leg uses the A1 from Linz to Krems (S33).

• Fuel stations: Frequent along A8, A93, and A1, but sparse on the B179 Fern Pass. Fill up in Garmisch-Partenkirchen or Lermoos.
• Tolls: Vignette required for Austrian motorways (A8, A1, S33). Purchase at border shops or online.
• Road conditions: Well-maintained asphalt on motorways; Fern Pass can twist and narrow in sections.
