Szeged to Thun: Epic Road Trip Through Europe

Stretching over 1,050 kilometers from the Hungarian Great Plain to the Swiss Bernese Oberland, the Szeged to Thun drive is one of Central Europe's most diverse road trips. The route crosses eight major highways (M5, M7, A1, A9, A2, A1/A3, A6, A8) and passes through five countries: Hungary, Croatia, Slovenia, Austria, and Switzerland. A curious fact: near the Slovenian-Austrian border, the highway briefly runs through a 500-meter tunnel that was originally built as a Cold War bunker.

The drive takes approximately 10-12 hours of pure driving time, but stretching it over two or three days uncovers a treasure trove of cultural and natural wonders. Is it worth driving Szeged to Thun? Absolutely. The contrast between the flat, paprika-scented Hungarian plains and the jagged, snow-capped Swiss Alps is a spectacle of geography and history. Using how to find the best stops and hidden gems between cities can transform this long highway cruise into an unforgettable journey.

The backbone of the journey is the E71/E65/E55 corridor, with key stretches on the Hungarian M7, the Croatian A1, Slovenian A1, Austrian A2/A9, and Swiss A6/A8. Tolls are required in Hungary (vignette), Austria (vignette), and Switzerland (vignette). Cash or credit cards are accepted at all borders. Fuel costs vary significantly: as of May 2025, Hungary offers the cheapest petrol (€1.35/liter), while Switzerland is the most expensive (€1.80/liter).

Driving times and distances: Szeged to the Lake Balaton region (2.5 hours, 220 km); Balaton to Ljubljana (3 hours, 260 km); Ljubljana to Salzburg (3.5 hours, 300 km); Salzburg to Thun (4.5 hours, 350 km). The total driving time is about 11 hours without stops. Fuel economy tip: fill up in Hungary or Slovenia before crossing into Austria for significant savings.

• Hungarian vignette: 10-day pass ~€15, available at border fuel stations.
• Austrian vignette: 10-day pass ~€9, available at OAMTC or online.
• Swiss vignette: annual pass ~€40 (no short-term option).
• Recommended fuel stops: Siófok (Hungary), Maribor (Slovenia), Villach (Austria), and Bern (Switzerland).

The journey begins on the Hungarian Great Plain, a flat expanse of sunflower fields and paprika farms. Near the border with Croatia, the landscape transitions to rolling hills and vineyards, particularly around the Balaton Uplands. The Balaton itself is Central Europe's largest lake, offering beaches, watersports, and the Tihany Peninsula with its medieval abbey.

Crossing into eastern Slovenia, the road winds through the forests of the Pohorje mountains. A detour to Ptuj, Slovenia's oldest town, reveals Roman ruins and a hilltop castle. Further west, the Austrian Alps emerge dramatically: the Karawanks and the Tauern range, with tunnels like the 5.5 km Karawanken Tunnel. The A10 south of Salzburg offers views of the Hohe Tauern National Park, home to the Grossglockner (3,798 m).

Switzerland begins with the Bernese Oberland. The A8 highway snakes along Lake Thun, with emerald-green water and the iconic peaks of the Jungfrau region. Thun itself is a picturesque medieval town on the lake's western shore, crowned by a 12th-century castle. Local commerce along the route includes Hungarian paprika markets, Slovenian crystal shops, Austrian Christmas markets (in season), and Swiss chocolate boutiques.

Road quality is excellent throughout: all highways are well-maintained and signposted in multiple languages. Speed limits: 130 km/h in Hungary and Croatia, 130 km/h in Slovenia and Austria, 120 km/h in Switzerland. Radar traps are common, especially in Austria. Winter tires are mandatory from November to April in Austria and Switzerland.

For families, the route offers endless possibilities. Stop at the Lake Balaton to let kids splash in the water (public beaches near Siófok). Near Ljubljana, the Postojna Cave Park includes a train ride through the cave and a salamander vivarium. Salzburg's Hellbrunn Palace has trick fountains and a petting zoo. In Switzerland, the Ballenberg Open-Air Museum near Interlaken showcases traditional Swiss houses and crafts.

Pet-friendly stops include the Hundewiese rest stops in Austria (fenced dog areas). Many hotels along the route (like the Ibis Budget in Graz, Austria) allow pets for a small fee. Fatigue management is critical on long Alpine sections. Scheduled breaks every 2 hours are a must. Rest areas like Rastplatz Schladming (Austria) have playgrounds, picnic tables, and stunning mountain views.

• Best rest stops: M7 Letenye (HU), A1 Lopata (SI), A9 Schladming (AT), A8 Spiez (CH).
• Hidden gems: Ptuj Castle (SI), the Ice Cave at Dachstein (AT), the Trümmelbach Falls (CH).
• UNESCO sites: Fertö/Neusiedler See (HU/AT), Hallstatt-Dachstein (AT), the old town of Bern (CH).
