St. Moritz to Krems an der Donau: Ultimate Road Trip Guide

The route from St. Moritz (1,822 m) to Krems an der Donau (203 m) traverses the Swiss Engadin, crosses the Austrian Alps via the Reschen Pass, and descends into the Danube Valley. A little-known fact: the Reschen Pass road holds the record for the longest continuous gradient in the Alps, descending 1,200 meters over 30 kilometers.

This drive offers stark contrasts: from glacial lakes to vineyard terraces. The 500 km journey typically takes 6.5 hours without stops, but you should allocate at least two days to appreciate the highlights. For tips on how to find the best stops and hidden gems between cities, consult local detours.

Safety and Road Quality

Austrian autobahns have no speed limit on some sections, but police enforce with radar. The B3 Danube road has speed limits of 70-100 km/h. Winter conditions demand caution on the Reschen Pass – black ice often forms in shadowed curves.

Family and Child Suitability

St. Moritz offers playgrounds and the Muottas Muragl funicular. In Nauders, the Bergkastel cable car. Krems has the Lalinde adventure playground. Recommended: things to do between St. Moritz and Krems an der Donau include a stop at the Swarovski Kristallwelten in Wattens (near Innsbruck).

Pet-Friendly Framework

Swiss hotels are generally pet-friendly; Austrian rest stops (Raststationen) allow dogs on leash. Keep vaccination papers ready. Most restaurants in Krems have outdoor terraces for pets.

Fatigue Management and Rest Zones

Take breaks every 2 hours. Rest stops on A1: Vomp (huge Raststation), and St. Pölten. For a unique stop, use the guide to find hidden farm-cafés along B-roads.

Hidden Off-Route Spots

Detour 10 km to Hallstatt (World Heritage) from the A1 – but expect crowds. Near Krems, visit the ruined castle of Aggstein, or the Maria Taferl basilica with Danube views.

Culinary Infrastructure

St. Moritz: fine dining (Chesa Veglia). Along the way: Tyrolean Groestl (pan-fried potatoes) at Jausenstationen. Krems: Heurigen (wine taverns) serve local wine and buffet food. Vegetarian options are limited in rural areas but available in larger towns.

Alpine Lakes and Meadows

Immediately after St. Moritz, Lake Silvaplana and Lake Sils offer turquoise water. Stop at Maloja Pass to photograph the 11-km long Lake Sils. The Engadin valley floor is dotted with Swiss stone pine forests.

• Silvaplana: windsurfing spot, summer only.
• St. Moritz Bad: thermal springs open year-round.

UNESCO World Heritage Sites

The route passes two UNESCO sites. The first is the Rhaetian Railway landscape (Albula/Bernina) near St. Moritz, though not driveable by car. The second is the Wachau Cultural Landscape around Krems, a 30-km stretch of the Danube Valley.

1. Wachau Valley: terraced vineyards, apricot orchards, and medieval towns.
2. Krems: Altstadt (old town) with Gothic churches and wine taverns.

Local Commerce and Souvenirs

In St. Moritz, buy Engadin nuts or Swiss chocolate. In Landeck, Austrian cheese and schnapps. The Wachau region is famous for its Grüner Veltliner wine and apricot products.

Fuel stations become sparse above 1,500 m; plan to fill up in St. Moritz (Swiss prices ~2.0 CHF/L) and again in Nauders (Austrian ~1.5 EUR/L). The Reschen Pass has no petrol stations for 40 km.

• Vignette required on Austrian highways: 10-day for €9.90.
• Winter tires mandatory from Nov 1 to Apr 15 in Austria.
• Swiss motorway sticker (40 CHF) needed if using A13.

Road quality is excellent: Swiss sections are pristine asphalt; Austrian highways are well-maintained. However, the Reschen Pass (B27) can be narrow and winding, with some gravel sections after snowmelt. The Danube B3 road has many curves but is well surfaced.

For those wondering how long to drive St. Moritz to Krems an der Donau, the answer is 6.5 hours pure driving. But adding stops for lunch, photos, and coffee will extend to 10-12 hours. To answer is it worth driving St. Moritz to Krems an der Donau, absolutely: the scenery is among the best in Europe.
