Graz to St. Moritz Road Trip: Alpine Drive Guide

The A9 motorway south of Graz was built over the Plabutsch tunnel, a 10 km engineering feat that was the longest road tunnel in Austria when it opened in 1987. You'll enter that tunnel just 10 minutes into your drive from the city center. This route combines high-speed Austrian autobahns with winding Alpine passes. It covers approximately 620 km and takes 7-8 hours of pure driving time, but you'll want to add stops. Knowing how long to drive Graz to St. Moritz is just the start; the question is it worth driving Graz to St. Moritz is answered yes once you see the landscapes. Use our guide to find the best stops Graz to St. Moritz.

We'll cover fuel costs, climate, road quality, and hidden detours. For more tips, check out how to find the best stops and hidden gems between cities.

The main route is via the A9 south to Klagenfurt, then A2/E66 west to Villach, followed by B100 to Spittal an der Drau, B108 over the Großglockner High Alpine Road (toll, €41 for cars), or the cheaper Felbertauern Tunnel (€12). Alternatively, take B100 through Lienz and then over the Reschenpass (SS40) into Italy and up to St. Moritz. This avoids the expensive Großglockner toll.

• Fuel: Expect €1.50-1.70/litre in Austria, €1.80-2.00 in Switzerland. Fill up in Austria before crossing.
• Tolls: Austrian motorway vignette required (€9.90 for 10 days). Swiss motorway vignette €40 (annual).
• Swiss Customs: You may be stopped for a vehicle check. Carry your passport and car documents.
• Speed limits: Austria 130 km/h autobahn, Switzerland 120 km/h motorway, reduced to 80 km/h on mountain roads.

The biggest hazard is the Alpine tunnels. Some have height and width restrictions. Always check your car's dimensions. Snow chains are mandatory in winter on passes like Reschen and Großglockner. Fatigue management is vital: Plan a stop every 2 hours. The rest area Wörthersee (east of Klagenfurt) has a playground and a supermarket. For families, the Minimundus miniature park in Klagenfurt is a hit. Pets are welcome at most gas stations, but keep them leashed. Switzerland requires a pet passport for dogs.

• Pet-friendly stops: Nature trails around Lake Weissensee (Carinthia).
• Child-friendly: Reptilienzoo Happ in Klagenfurt or the Ötzi Village in Umhausen.
• Safety: Keep headlights on in tunnels. Emergency phones every 200 m.

From the Styrian wine hills to the Dolomites, this route is a geological gallery. The first notable landscape is the Zirbitzkogel-Grebenzen Nature Park, just off the A2 near Judenburg. Then the Drau River valley leads to Lienz, surrounded by the Lienz Dolomites. Crossing the Reschenpass at 1,504 m, you'll see the iconic lake with a submerged church tower in Graun. Things to do between Graz and St. Moritz include visiting the Swarovski Crystal Worlds in Wattens, Hallstatt (a bit north), or the Engadin valley's turquoise lakes.

• UNESCO Sites: Hallstatt-Dachstein/Salzkammergut (approx. 200 km detour) and the historic center of Graz itself.
• Local crafts: Carinthian wooden cheese boards, Engadin nut cakes.
• Stop at a Bauernladen (farm shop) for fresh cheese and Speck.
