St. Moritz to Ulm Road Trip Guide: Alpine Views & Historic Towns

The drive from St. Moritz to Ulm covers approximately 300 kilometers, winding through the Swiss Engadin valley, crossing the Austrian border, and climbing over the Arlberg Pass before descending into the Bavarian and Swabian landscapes. This route features the A13/E43 highway in Switzerland, the S16 Arlberg Schnellstraße in Austria, and the A7 in Germany.

A little-known fact: the St. Moritz–Ulm route roughly follows an ancient salt trading path that connected Venice to Augsburg. Today, the drive offers a microcosm of European geography, from Engadin's fir forests to the undulating hills of Upper Swabia.

The route offers a dramatic transition: from the deep green Engadin Valley with its crystal-clear lakes (Lake St. Moritz, Lake Silvaplana) to the rugged limestone peaks of the Arlberg massif, then descending into the gentle hills of Bavarian Swabia. The contrast is striking: the Swiss section is narrow and flanked by dense forests; the Austrian side opens onto broad valleys dotted with dairy farms; Germany features rolling agricultural land and river meadows.

Must-see natural attractions between St. Moritz and Ulm:

• Lake Silvaplana (Switzerland) – ideal for windsurfing, with a backdrop of Piz Corvatsch.
• Sertig Valley (side trip to a remote alpine hamlet, 20 min detour).
• Arlberg Panorama – stop at the tunnel portals for sweeping views of the Alps.
• Iller River Valley (Germany) – scenic stretch along the A7 near Memmingen.

Local commerce and cultural highlights: The route passes through traditional towns where you can buy Swiss cheese (Engadin), Austrian schnapps (Langen am Arlberg), and Swabian noodles (Spätzle from Memmingen). The how to find the best stops and hidden gems between cities guide can help you plan detours into craft breweries and farm shops.

• St. Moritz: upscale boutiques and Swiss watches; skip if on budget.
• Landeck (Austria): local farmer’s market on Saturdays (8am-12pm).
• Memmingen: medieval old town with half-timbered houses and a brewer’s guild.

Infrastructure safety & road quality: All three countries maintain high safety standards. Swiss roads have sharp curves and short tunnels; Austrian S16 is modern but has sudden elevation changes (6% gradient). German autobahn can have heavy traffic near Ulm. Winter conditions: mandatory winter tires in Austria from Nov 1 to Apr 15; chains recommended for Swiss side roads.

• Emergency phones every 2 km on Austrian autobahn.
• Radar traps common in Switzerland and Austria; speed limits strictly enforced.
• German sections: watch for construction zones with temporary narrow lanes.

Family and child suitability: The route is family-friendly with many rest stops offering playgrounds and clean WC. Highlights for kids: children’s play areas at Swiss service stations (e.g., Raststätte Maienfeld); the Arlberg Tunnel is an adventure – bring snacks for the short drive. In Germany, the Legoland Discovery Centre at the A8 near Ulm (if time allows).

• Rest stops every 40-60 km with baby changing facilities.
• In-car entertainment: audiobooks about the Alps or search for local legends.
• Tip: book a break at Schwangau (exit A7) to see Neuschwanstein Castle from the road – a quick up-hill walk.

Pet-friendly framework: All rest stops allow dogs on leash; many service stations have dog relief areas with waste bags. Austria requires a pet passport (EU standard). Switzerland: dogs must be microchipped and rabies vaccinated. Hotels in Memmingen and Ulm generally accept pets (fee ~€10-20/night).

• Plan stops at: Raststätte Oberhof (Switzerland) – large green area; Raststätte Buxach (Germany) – dog park.
• Never leave pets in the car; moderate temperatures in summer.
• Check that the pet is included in the vignette/pass details – not required for vehicles, but keep vaccination record handy.

Fatigue management & rest zones: Recommended rest stops (every 90 minutes or so):

1. After 1h: Raststätte Engadin (Switzerland) – view of mountains and coffee.
2. After 2h 15min: Landeck service station (Austria) – underground garage with resting lounge.
3. After 3h: Herrsching am Ammersee (Germany, 15 min detour) – lakeside meadow for a 20-minute power nap on a bench.

Route choice: The fastest route from St. Moritz to Ulm involves taking the main road toward the Austrian border via the Engadin valley, joining the A13/E43 north to the S16 (Arlberg Schnellstraße), then continuing on the A96/E43 and A7 into Germany. Total driving time is about 3.5 to 4 hours without stops.

• Swiss section (St. Moritz to Austrian border): main road H2, then A13 – well-maintained, but watch for wildlife after dark.
• Austrian section (Arlberg): S16 toll road – requires a vignette (10-day €9.90); the tunnel may have queues in peak ski season.
• German section: A96 and A7 – autobahn with sections unlimited speed; expect traffic near Memmingen and Ulm.

Fuel and route economics: Fuel prices vary: Switzerland (€1.80/L), Austria (€1.50/L), Germany (€1.70/L). Fill up in Austria for best value. Toll costs: Austrian vignette (€9.90) and Swiss vignette (already required if driving in Switzerland). No tolls on German autobahn for cars.

• Swiss vignette: 40 CHF (about €41) for 14 months, valid for cars.
• Arlberg Tunnel: toll included in S16 vignette; no extra fee.
• Reserve cash for Swiss motorway service stations – some don’t accept cards.

Best time to drive: May–September for clear weather and green landscapes; October for autumn colours; winter requires snow tires and chains due to passes. The Arlberg Pass (S16) is a tunnel, so winter open, but icy roads possible.
