Polignano a Mare to Davos: Epic Road Trip Guide

Few routes juxtapose such stark opposites as the 1,100 km drive from Polignano a Mare's limestone cliffs to Davos' Alpine snowfields. The journey begins on the A14 at exit 11 (Polignano), crosses the Apennines on the A1, skirts the Po Valley, and ascends the San Bernardino Pass (A13/E43) into Switzerland. The total driving time without breaks is roughly 11–12 hours, but factor in 2–3 days for optimal enjoyment.

This guide follows the spine of Italy's Autostrada del Sole and the Swiss A13, weaving through UNESCO sites, culinary capitals, and hidden valleys. For more on discovering off-the-beaten-path gems, see how to find the best stops and hidden gems between cities.

The backbone is the Italian A1 (toll road) and Swiss A13 (vignette required). Toll costs from Polignano to the Swiss border average €55–€65 for cars. Swiss vignette costs CHF 40 (valid for calendar year). Fuel costs along the route vary: diesel in Italy ~€1.80/L, in Switzerland ~CHF 1.90/L.

• Italian Autostrade: A14 from Bari to Bologna, then A1 north. Exits clearly signed, service areas every 30–40 km.
• Swiss A13: Well-maintained, but tunnels and bridges common. San Bernardino Pass tunnel (6.6 km) avoids summit road in winter.
• Milestones: Polignano (km 0), Bologna (km 680), Milan (km 830), Chiasso (km 1000), Davos (km 1100).

• Service stations: Autogrill (Italy), Raststätte (Switzerland) with clean toilets, restaurants, and EV chargers.
• Currency: Euro in Italy, Swiss Franc in Switzerland. Credit cards widely accepted.

Safety infrastructure is excellent. Italian Autostrade have SOS phones every 2 km and speed cameras (limit 130 km/h). Swiss A13 has variable speed limits in tunnels. Winter tires are mandatory in Switzerland from Nov 1 to Mar 31; chains may be required on San Bernardino if conditions worsen.

• Infrastructure Safety & Road Quality: Italian motorways well-paved; Swiss asphalt pristine. Watch for sudden fog in Po Valley and ice on Alpine bridges.
• Fatigue Management & Rest Zones: Plan stops every 2 hours. Recommended: Arezzo service area (A1, km 345) with quiet zone, and San Bernardino rest stop (A13) with panoramic views.

Pet-friendly framework: Most Italian service areas allow dogs on leash; Swiss hotels and restaurants are very pet-friendly, with dedicated zones. Hidden off-route spots include the medieval village of Bergamo Alta (just off A4) and the Verzasca Valley (off A13) with its crystal-clear swimming holes.

• Hidden Off-Route Spots: Montefeltro hill towns (San Leo), Val di Mello granite valley, and the wild resevoir of Lago di Lei.
• Climatic Conditions & Route Aesthetics: Spring (Apr-Jun) offers wildflowers in Apennines; autumn (Sep-Oct) has crisp air and golden larches in Alps. Winter driving requires caution.

The route slices through four distinct natural zones: the Adriatic coast (coves, olive groves), the Apennine mountains (forested ridges), the Po Valley (flat farmland), and the Swiss Alps (granite peaks, pine forests). Each offers unique stops for things to do between Polignano a Mare and Davos.

• Natural Landscapes & Attractions: Gargano National Park (detour to Vieste), Monte Conero near Ancona, Lake Como (detour), and the Swiss National Park near Zernez.
• UNESCO World Heritage Sites: Castel del Monte (detour), Historic Centre of Florence, Bellinzona's Three Castles, and Rhaetian Railway in the Albula/Bernina landscapes.

Local commerce thrives in medium-sized towns: Modena for balsamic vinegar (Acetaia di Giorgio), Parma for Parmigiano-Reggiano, and St. Moritz for luxury boutiques. Farmers' markets along the route sell seasonal produce—taste the differences between Italian Apulian olive oil and Swiss Alpine cheese.

• Culinar Infrastructure: Michelin-starred options (Osteria Francescana in Modena), Autogrill panini, Swiss mountain restaurants (Berghaus).
• Family & Child Suitability: Service areas with playgrounds (e.g., Cantagallo on A1), Swiss Legoland in Chur, and tame Alpine trails near Davos.
