Garmisch-Partenkirchen to Sion Road Trip Guide

Driving from Garmisch-Partenkirchen to Sion covers 420 km through three countries – Germany, Austria, and Switzerland – with the Fernpass and Arlberg massifs as key obstacles. The route follows the B2, A12, and A13, taking roughly 5 hours without stops. A local quirk: the Arlberg tunnel in Austria charges a toll on top of the standard vignette, catching many drivers off guard. how to find the best stops and hidden gems between cities.

This route traces the Lech River valley, crosses the Alpine divide at Arlberg Pass (1,793 m), and descends into the Upper Rhône valley. The journey offers dramatic geological contrasts: limestone peaks near Garmisch give way to gneiss and schist in the Engadin region, then glacially carved valleys into Valais. For those wondering how long to drive from Garmisch-Partenkirchen to Sion, the actual driving time is 4.5 to 5.5 hours depending on traffic and border checks.

Fuel stations are abundant along the A12 corridor but thin out on the A13 after Chur. You can fill up for €1.60-1.80 per liter in Austria, while Swiss stations near Sion cost €1.90-2.10. For fuel efficiency, keep speed below 110 km/h on the Arlberg incline; the climb consumes 20% more fuel. Recommended stops for refueling: Landeck (A12) and Chur (A13).

• Average fuel cost (gasoline) for the full route: €55-70.
• Alternative fuel (diesel): typically €0.10 cheaper per liter.
• Electric charging points: limited in Austrian alpine sections; plan stops at Fernstein See or Bludenz.

GPS coordinates for key junctions: Fernpass peak at 47.3457° N, 10.8349° E; Arlberg tunnel entrance at 47.1266° N, 10.1581° E. The Swiss customs office at St. Margrethen (border crossing) may inspect vehicle contents; carry vehicle registration and ID. No vignette needed for the German portion (free autobahn). Note: Switzerland uses an annual vignette – no short-term option – so factor that cost.

• Border crossing Germany-Austria near Ehrwald: minimal delays (5 min).
• Austria-Switzerland at St. Margrethen: may have longer queues on weekends.

The landscape shifts from the lush green Loisach valley past Garmisch to the rugged limestone of the Wetterstein range. As you climb Fernpass, the terrain becomes a high moorland with alpine meadows. Descending into the Lech valley, you encounter the jagged Allgäu Alps via Lechtaler Alpen. After Landeck, the road follows the Sanna River through narrow gorges before rising to the Arlberg massif – a watershed divide between the Danube and Rhine basins.

• Fernpass (1,210 m): panoramic view of Zugspitze on a clear day.
• Lech valley: emerald green water, known for trout fishing.
• Arlberg region: ochre-colored rocks in the Rosanna gorge.

Just off the highway near Zams (5-min detour), you can visit the 13th-century Landeck Castle housing local folklore. Another hidden gem: the Wiesberg Castle ruins perched above the Inn river – visible from the A12 after Pians. For authentic commerce, stop at a Speckstube in Pettneu am Arlberg to buy regional Tyrolean Speck (cured ham).

• Landeck's weekly market (Wednesdays): cheeses, bread, woodcarvings.
• Arlberg farm stands: rye schnapps and alpine honey.

UNESCO World Heritage Sites: The route passes near the “Prehistoric Pile Dwellings around the Alps” UNESCO site, but the closest accessible one is at Greifensee (Zurich area), a 90-min detour. However, the core route itself doesn't include any UNESCO objects; the closest is the Old City of Bern (~2 hours south). Nonetheless, the entire Alpine region is part of the UNESCO “Alpine Parks” Biosphere Reserve.

Road quality is excellent on the Austrian A12 motorway, but the B2 from Garmisch to the Austrian border is a two-lane road with occasional potholes after winter. Night illumination: the A12 is fully lit until Landeck; the Arlberg tunnel has bright LED lighting. After the tunnel, the Swiss A13 has no lighting except in tunnels – use high beams when safe.

• Safety tips: Watch for livestock crossings on the B2 near Mittenwald.
• Winter risk: snow chains mandatory on Fernpass if slippery (November-April).
• Police presence: speed traps common on A12 near Imst.

For families, the Alpentherme Erlebnisbad in Ehrwald (just after the border) is a giant indoor water park with slides – ideal after hours of driving. Another option: the Area 47 leisure complex near Ötztal offers summer bobsled racing and a climbing park. Both have ample parking and on-site food.

• Interactive museum: Haus der Steine in Völs (A12 exit) – mineral collection and earthquake simulator.
• Children's farm: Bäuerliches Erlebnis in Pettneu – pet goats and learn butter-making.

Pet-friendly stops: the Raststätte Landgasthof Klösterle at A12 exit has a designated dog meadow with water bowls. Also, the Obermarkt in Landeck allows dogs on leash. For walking, take a break at the Plansee lake near Reutte – a 10-min detour with a dog-friendly trail.

• Pet policy in Swiss restaurants: most require dogs on leash and no furniture.
• Poop bags: available at many fuel stations in Austria.

Fatigue management: The best rest zones are the Arlberg massif car park (entrance east side) with panoramic views, and the Raststätte Mels in Switzerland (A13). Both have clean bathrooms and are safe for napping. If drowsy, pull into the “Autobahnparkplatz St. Anton” – a quiet spot with short walking trails.

• Recommended nap spots: Parkplatz Gries (A12) – shaded and flat.
• Emergency contact: Austrian Road Assistance (ÖAMTC) 120, Swiss (TCS) 0800 140 140.
