Bellinzona to Davos: Alpine Drive Guide

The A2 highway from Bellinzona to Davos crosses the San Bernardino Pass, a route that shifts from Mediterranean-like valleys to high alpine terrain in under two hours. The drive covers 120 km and typically takes 1 hour 45 minutes without stops. This route is a geological corridor where you witness the transition from Ticino's granite peaks to Graubünden's limestone massifs, a fact visible in the changing rock colors along the roadside.

For those wondering how to find the best stops and hidden gems between cities, this guide provides detailed insights into every turn. The Bellinzona to Davos drive is not just about reaching the destination; it's about experiencing the layers of Swiss culture and nature. Whether you ask "how long to drive Bellinzona to Davos" or "is it worth driving Bellinzona to Davos," the answer lies in the journey itself.

The geographical shift is dramatic: you depart from Bellinzona at 240m altitude, surrounded by vineyards and palm trees, then ascend through the Ticino valley to the San Bernardino Pass (2,066m). After the tunnel, the landscape transforms into the rugged Graubünden region with pine forests and alpine meadows. The final stretch into Davos (1,560m) offers panoramic views of the Flüela Pass and the Davos Lake.

• Best Landscape Stops: At the San Bernardino Pass viewpoint (E42, 46°28'12"N 9°11'24"E), you can park and photograph the Ticino valley. Near Thusis, the Viamala Gorge (46°39'36"N 9°27'00"E) is a spectacular canyon worth a 10-minute detour – a short walk leads to the bridge over the gorge.
• Local Commerce and Culture: In San Bernardino village, a small cheese dairy sells Alpkäse (Alpine cheese) and cured meats. At Thusis, the weekly market (Wednesdays) offers local honey, Graubünden nut cakes, and hand-carved wooden crafts. On the way to Davos, the village of Wiesen has a pottery studio where you can watch artisans at work.
• UNESCO Detour: The Benedictine Convent of Saint John in Müstair (UNESCO) is a 30-minute detour from Zernez (drive towards Val Müstair). This Carolingian monastery features 1,200-year-old frescoes. Open daily, entry CHF 12.

Climatic Conditions: The weather varies significantly: Bellinzona enjoys mild Mediterranean climate; the San Bernardino region can have sudden fog and snow even in summer (temperatures drop 10°C). The best time for sunset views is from the Davos side, where the Rinerhorn or Jakobshorn give clear views of the setting sun behind the Alps. Avoid driving during heavy snowfall – winter tires are mandatory from November to April.

Safety is paramount: the A13 motorway has emergency phones every 2 km. The San Bernardino Tunnel has speed cameras and strict no-overtaking rules. On the mountain road to Davos (Hauptstrasse 18), watch for gravel trucks and occasional livestock crossings. For night driving, use high beams on unlit sections but dim for oncoming traffic.

• Fuel and Rest Zones: The motorway service area at San Bernardino (Shell station) includes a cafe and restrooms. Another safe rest stop is at Thusis (Migrol station) with a picnic area. For a nap, the parking bay at Splügen (46°32'24"N 9°18'36"E) is level and quiet, with a view of the Rhine. Avoid parking on the winding road sections.
• Family and Child Suitability: The Swiss Transport Museum in Bellinzona (the starting point) has interactive exhibits on alpine transportation. At San Bernardino, the Alpine Garden (free entry) lets kids play in a safe, fenced area. In Davos, the Kirchner Museum offers family tours, and the Bolgenplatz playground has adventure equipment. The Rhaetian Railway from Thusis to Davos (part of the Bernina route) is a UNESCO World Heritage line that delights children with its panoramic railing.
• Pet-Friendly Framework: Dogs are welcome in most outdoor areas. The San Bernardino service station has a dog run (fenced). The restaurant Pöstli in Thusis allows well-behaved dogs on the terrace. In Davos, the Seehofgarten cafe provides water bowls. Many hiking trails near Davos are leash-free (local rules apply).

Culinary Infrastructure: For a true regional meal, try the Capuns (chard rolls with meat) at Restaurant Bundnerhof in Thusis. In San Bernardino, the Albergo San Bernardino serves Polenta with braised beef – a Ticinese specialty. For a quick snack, the bakery at Splügen sells fresh Bündner Nusstorte (nut cake). Vegetarians can find options at the health food store in Davos (Reformhaus).

Hidden Off-Route Spots: Just 5 minutes off the A13 at Splügen, the abandoned village of Medels im Rheinwald (46°30'00"N 9°15'36"E) features a ruined church and empty stone houses, offering a spooky yet photogenic stop. Another hidden gem: the Bawler waterfall near Thusis (5-minute walk from the car park at bus stop Bawler Dorf), a cascading 30-meter fall often missed by drivers.

Fatigue Management: Plan to stop twice: once at San Bernardino (20 min) and once at Thusis (15 min). The drive is mentally demanding due to the tunnel and curves. Coffee at the San Bernardino Autogrill is strong and reliable. If feeling drowsy, safer to stop at Splügen (quiet parking) for a nap. Keep a blanket and water in the car.

The route primarily uses the A13 highway via San Bernardino, then the A13 towards Thusis and finally the main road to Davos. The most critical point is the San Bernardino Tunnel (16.5 km, toll included in the annual Swiss vignette). The road is well-maintained, with a speed limit of 80 km/h in the tunnel and 120 km/h on open sections. Expect heavy traffic during winter weekends.

• Fuel and Route Economics: Fuel costs for a round trip (240 km) in a mid-size car: approximately CHF 45-55 (petrol) or CHF 25-35 (diesel). Fuel stations are abundant in Bellinzona, San Bernardino village, Thusis, and Davos. Use the A13 services at San Bernardino for the best prices. Driving at a constant speed on the A13 minimizes fuel consumption; the alpine sections require more fuel uphill.
• Toll and Vignette: Switzerland requires a valid vignette (CHF 40) for all vehicles on motorways. The San Bernardino Tunnel is covered. No additional tolls. Rental cars usually include the vignette – confirm in advance.
• Road Quality: The A13 is a motorway with smooth asphalt. The section from Thusis to Davos (Hauptstrasse 18) is a winding mountain road with good surface but sharp curves. Night illumination is present only on the A13; the mountain road to Davos is poorly lit – drive with caution after dusk.

UNESCO World Heritage Sites: While the route itself does not pass directly through a UNESCO site, the Bellinzona Castles (three castles and fortifications) are a UNESCO World Heritage Site located at the starting point. A short detour of 15 minutes adds the Benedictine Convent of Saint John in Müstair (UNESCO) if you deviate east from Zernez.
