Polignano a Mare to Thun: Ultimate Road Trip Guide

The road from Polignano a Mare (40.9947° N, 17.2176° E) to Thun (46.7580° N, 7.6299° E) spans roughly 1,200 kilometers. The journey crosses three countries: Italy, Austria, and Switzerland. A little-known fact: the final Alpine descent into Thun passes the Aare Gorge, where the river has carved a 1.4-kilometer-long limestone canyon over 200,000 years.

Drivers typically need 12–14 hours without stops. The optimal route uses the A14 from Bari to Bologna, then the A1/E35 to Milan, then the A4/E64 to Bergamo, then the A36/SS36 to the Swiss border at Chiasso. From there, the A2/E35 climbs through the Gotthard Base Tunnel (57 km, the world’s longest railway tunnel; road tunnel is 16.9 km) to Lucerne, then the A6/E35 to Bern and finally Thun.

For those wondering how to find the best stops and hidden gems between cities, this guide offers exhaustive detail.

Infrastructure and Road Quality

The Italian A14 and A1 are modern toll highways in good condition, though some stretches near Bologna have concrete surfaces that can be noisy. Swiss A2 and A6 are excellent, with smooth asphalt and clear signage. In winter, snow and ice may affect the Swiss alpine sections between Altdorf and Lucerne; winter tires are mandatory from November to April in Switzerland.

Accident risk is low on motorways, but beware of speed cameras in Italy (limit 130 km/h, 110 in rain) and Switzerland (120 km/h, fines up to CHF 1,000).

Family and Child Suitability

Polignano a Mare has a pebble beach and the Lama Monachile gorge, but it’s more suited to older children. The route’s best family stop is Gardaland near Peschiera del Garda (exit on A4 before Milan). This amusement park offers rides for all ages and can break the drive at the midpoint. For nature-loving families, the Swiss Transport Museum in Lucerne (exit A2 Luzern) is excellent.

• Kid-friendly food: Autogrills sell pasta, pizza, and panini; Swiss Raststätten have fresh rolls and fruit.
• Baby-changing facilities: Available at most Italian autogrills; Swiss rest stops have designated family rooms.

Pet-Friendly Framework

Dogs are welcome in many pit stops. Italian autogrills allow pets on leashes in outdoor areas; some have designated pet areas. Swiss Raststätten generally permit dogs inside provided they are leashed and do not disturb others. In Thun, the Hotel Gastlosen and others offer pet-friendly rooms (extra fee ~CHF 15).

• Veterinary: In Italy, animal clinic chain “Ambulatorio Veterinario” near A1 exits; in Switzerland, “Tierarzt 24” near A2 at Sursee.

Fatigue Management & Rest Zones

Driver fatigue is the biggest risk on long-distance trips. Plan a stop every 2 hours or 200 km.

• Recommended stops: area di servizio “Pescara Ovest” (km 400 on A14) – large Autogrill with coffee bar, pizzeria, and outdoor seating. “Cantagallo” (km 278 on A1) – scenic overlook with view of the Apennines. “Gotthard Süd” (Swiss A2) – before the tunnel, with panorama of the Lepontine Alps.
• Quick nap: pull into a rest area’s truck parking; use a sleep mask and earplugs.

Hidden Off-Route Spots

Two secrets: the medieval village of Gubbio (40 km off A1 at Perugia exit) features the world’s largest Christmas tree (lit on Dec 7th). In Switzerland, the Aare Gorge near Meiringen (20 km south of Thun) has a 1-km-long footbridge through the canyon – a breathtaking 30-minute stop.

For foodies: near Bologna, the Osteria della Ghiaiara (off A14 at Imola) serves real ragù alla bolognese. In Thun, the Mühleplatz farmer’s market (Saturdays) offers fresh cheese and bread.

Culinary Infrastructure

Italian autogrills are superior to Swiss Raststätten for variety. At “Area di Servizio Cantagallo” try the fresh pasta bar and the espresso machine. Swiss rest stops like “Würenlos” have a Migros supermarket with ready-to-eat salads and sandwiches. For a sit-down meal, exit at Ravenna (A14) for seafood, or at Bergamo (A4) for casoncelli pasta.

Thun’s culinary scene includes the Schlosshügel restaurant (traditional rösti and fondue) and the Krone Thun for modern Swiss cuisine.

Climatic Conditions & Route Aesthetics

Spring (April–May) and fall (September–October) offer the best weather: mild temperatures, green landscapes, and fewer tourists. Summer can be hot (35°C in the Po Valley) and crowded at Swiss attractions. Winter sees snow in the Alps, but the highways are cleared; the Gotthard Base Tunnel eliminates the risk of pass closures.

Aesthetic highlights: sunset over the Adriatic Sea near Polignano a Mare, golden hour over the Po rice fields near Vercelli, and the mist-covered Alps from the A2 near Lucerne.

Fuel stations are frequent on Italian autostradas (every 20–30 km). In Switzerland, they are less common on the A2; refuel before entering the Gotthard Base Tunnel area. Tolls: Italy charges roughly €45 for the entire A14 + A1 + A9 stretch. Switzerland requires a vignette (CHF 40) for cars, valid for 14 months starting from the purchase date (calendar year).

• Italy: pay at toll booths (cash, credit card) or use Telepass. Switzerland: buy vignette at border or gas stations.
• Petrol price: Italy €1.80/L (95). Switzerland CHF 1.70/L (95).
• Rest areas: Italian autogrills (e.g., Cantagallo, Firenze Ovest) offer fuel, food, toilets. Swiss Raststätten (e.g., Würenlos, Neuenkirch) have similar services.
• Electric vehicle charging: Fastned and Ionity along A1; Swissgrid along A2.

Parking in Thun: city garages like Zentrum Parkhaus (CHF 2.50/hour) or Altstadt garage (CHF 2.00/hour). Many hotels offer free or discounted parking.

Adriatic Coast to the Apennines

The first 200 km from Polignano a Mare to the Gargano Peninsula are flat olive groves and coastal cliffs. After Vasto, the A14 climbs into the Apennine mountains near Pescara, offering views of the Maiella massif. The landscape transitions from Mediterranean maquis to oak and beech forests.

Local commerce: stop at a frantoio (olive oil mill) in Bisceglie to buy fresh olio novello. Near Pescara, roadside stalls sell arrosticini (sheep skewers) and confetti di Sulmona (almond candies). In the Marche region near Ancona, try vincisgrassi (lasagna) and verdicchio wine.

Po Valley and Pre-Alps

From Bologna to Milan, the A1 crosses the flat Po Valley, a patchwork of rice fields, corn, and poplar rows. The skyline includes the towers of Bologna’s due torri and the cathedral of Modena. Near Piacenza, the route skirts the foothills of the Apennines, with castle towers visible from the autostrada.

Commerce: Piacenza is known for salumi (Piacenza coppa). In Lodi, look for Robiola cheese and local miele (honey). Just before Milan, the Serravalle outlet (50+ stores) offers fashion discounts.

Swiss Alps and Lake Thun

After crossing the border at Chiasso, the A2 climbs through the Ticino valley, passing Lugano and its lake. The Gotthard Base Tunnel bypasses the old pass road, but views of the Alps still appear at exits. After the tunnel, the landscape opens into the Reuss valley, with the Reuss River cascading toward Lake Lucerne. The final 30 km from Bern to Thun run along the Aare River, with the Bernese Alps dominating the horizon.

Local commerce: in Thun, the Zibelemärit (onion market) in November sells braided onions and paper flowers. Year-round, shops in the Altstadt offer watches (Swatch, Omega), Swiss army knives (Victorinox), and chocolates (Läderach, Sprüngli).

UNESCO World Heritage Sites

Three UNESCO sites are accessible with minimal detours: the Trulli of Alberobello (30 km inland from Bari), the Historic Centre of Florence (exit at Firenze Sud on A1), and the Old City of Bern (15 km west of Thun). Each can be visited with a 1–2 hour stop.

• Alberobello: 400 trulli houses; suggested stop at Largo Martellotta for panoramic views.
• Florence: see the Duomo and the Uffizi; park at Garage Lungarno.
• Bern: visit the Zytglogge (clock tower) and bear pit.
