Polignano a Mare to Thun: Ultimate Road Trip Guide

Did you know that the Polignano a Mare to Thun route crosses the Apennine Mountains through the historic A14 and A1 highways, passing directly under the 2,300-meter-high Gran Sasso massif? This 1,100-kilometer journey from the Adriatic coast to the Swiss Alps takes approximately 10 hours of pure driving, without rests.

• Key highways: A14 (Adriatic), A1 (Sun Highway), A4 (Serenissima), A22 (Brenner), and Swiss A2.
• Estimated driving time: 10–12 hours depending on traffic and border crossing.
• Best stops incorporate both coastal and alpine views; learn how to find them with this guide on hidden gems.

This route is well-tolled in Italy: expect approximately €55 in tolls from Polignano to the Swiss border. Swiss vignette (€40) is mandatory for A2. Fuel stations are plentiful along A1 and A14, but sparse on A22 through the Brenner Pass.

• Fuel efficiency: Compact cars yield 6-7 L/100km; total fuel cost ~€130 (gasoline).
• Diesel is cheaper; filling up before entering Switzerland saves 20%.
• Nearly all Italian autogrills accept credit cards; Swiss stations require CHf or card.

Road quality is excellent throughout, but the Brenner Pass can be slippery in winter. Italian autostrade are well-lit at night; Swiss A2 has tunnels with strict speed limits (80 km/h).

• Family-friendly: Gardaland (Lake Garda), Bolzano's Ötzi Museum, and Swiss Transport Museum in Lucerne (detour 30 min).
• Pet-friendly: Rest areas along A1 near Firenze have dog parks; Swiss rest stops allow leashed dogs.
• Fatigue management: Pull-off areas at 'Badia al Pino' (A1), 'Brennero' (A22), and 'Wassen' (A2). Each has shaded parking for quick naps.
• Hidden off-route: Visit the abandoned village of Craco (exit A14 at Pisticci) or the ruins of Castel San Gottardo (exit A2 at Airolo).

The drive transitions from limestone cliffs and olive groves of Puglia to the flat Po Valley, then into the Dolomites and Swiss Alps. The change from Mediterranean to alpine climate is dramatic.

• UNESCO sites: Castel del Monte (detour 20 min from A14), Historic Centre of Florence (detour 30 min from A1), and Dolomites (near A22).
• Local goods: Olive oil in Puglia, Parmigiano Reggiano near Modena, speck from Alto Adige, and Swiss chocolate in Thun.
• Best sunset viewing: Lake Garda (exit A22 at Rovereto Sud) or the Grosser Aletsch Glacier viewpoint from A2 near Brig.
