Bellagio to Davos Road Trip: Alpine Drive Guide

The road from Bellagio on Lake Como to Davos in the Swiss Alps traverses 220 km of dramatic terrain, crossing the Italian-Swiss border at the Passo del Maloja (1815 m). The route includes the notorious M9 motorway stretch through the San Bernardino tunnel (16.9 km, one of the longest road tunnels in the Alps) and the winding Hauptstrasse 417 past the Albula Pass. The driving time typically ranges from 3.5 to 4.5 hours without stops, but the journey demands multiple pauses to absorb the shifting landscapes.

The journey begins on the SP71 along the eastern shore of Lake Como, connecting to the SS36 at Lecco. Take the SS36 north to Colico, then follow SS38 through the Valtellina valley to Chiavenna. At Chiavenna, cross into Switzerland via the J4/H4 to Passo del Maloja, descending into the Engadin valley. From St. Moritz, take the H27 over the Albula Pass to Davos.

• Fuel costs: Expect €80-100 for petrol (gasoline) for the entire trip, with prices higher in Switzerland (CHF 1.80/L vs €1.60/L in Italy). Diesel vehicles save ~15%.
• Fuel efficiency tips: The climb from Chiavenna to Maloja increases consumption by 20%; maintain steady RPMs and avoid hard acceleration.
• Fuel station distribution: Stations are frequent in Italy (every 20 km on SS38) but sparse in Switzerland between Maloja and St. Moritz. Fill up in Chiavenna last Italian station.
• Tolls: Italian autostrada tolls total ~€5 (SS36/SS38 are toll-free except a short segment near Lecco). Swiss motorway vignette (CHF 40) required for Swiss A13/E43 section, but the H4 and H27 are vignette-free.

Road quality is excellent throughout: SS38 is well-maintained two-lane; Swiss H4 and H27 are smooth asphalt with guardrails. Night lighting is present only near towns; alpine sections (Maloja, Albula) are unlit. Carry snow chains from October to May. Speed limits are strict: 50 km/h in villages, 80 km/h on open roads. The San Bernardino tunnel has a 100 km/h limit.

• Family and child suitability: Fun stops include the Swiss Transport Museum's branch in St. Moritz (interactive exhibition) and the playground at Lago di Poschiavo beach. The Swissminiatur park in Melide is 30 min off-route but worth a detour for kids.
• Pet-friendly framework: Dogs are welcome at most Alpine huts (e.g., Capanna in St. Moritz). Rest stops near Chiavenna have designated dog areas; beware of grazing cattle on open passes.
• Fatigue management & rest zones: Recommended nap spots: pull-off at the Maloja pass summit (parking area with view); the service area at La Punt (coffee, restrooms). For a safe sleep, book a room at Hotel Piz in St. Moritz (CHF 80).
• Hidden off-route spots: The abandoned village of Crespian (near Chiavenna) with ruins of medieval houses; the tiny chapel of San Rocco at 5 min drive from SS38, known for frescoes.

The route transitions from Mediterranean lakeside terraces to alpine pastures and high passes. Bellagio sits at 200 m elevation, while Davos lies at 1560 m. The Passo del Maloja offers a dramatic overlook of the Upper Engadin valley, where the Inn River originates. The Albula Pass, at 2315 m, features UNESCO World Heritage (since 2008) as part of the Rhaetian Railway in the Albula/Bernina Landscapes. Although the railway is not on the drive, the pass road itself passes through the UNESCO buffer zone, with viewpoints of the Landwasser Viaduct.

• Best stops Bellagio to Davos: Chiavenna's historic centre with Romanesque church San Lorenzo; the Lago di Poschiavo viewpoint; the village of Samedan (Switzerland's highest town at 1721 m).
• Things to do between Bellagio and Davos: Stop at the Museo Ciocco in Bellagio for olive oil tasting; hike the Val da la Pöscha trail near Maloja; visit the Alpacas farm at La Punt.
• Local commerce: Buy Bresaola (air-dried beef) in Valtellina; purchase Engadin nut cake in St. Moritz; pick up Swiss chocolate at the Läderach shop in Davos.
