Pécs to Konstanz Road Trip: Danube to Lake Constance Guide

In Pécs, the Zsolnay fountain on Széchenyi Square marks the start of an 800-kilometer drive to Konstanz. The route crosses four international borders and passes through the southern edge of the Alps. Most drivers take 8 to 10 hours of actual driving, but with stops, the trip easily fills two days.

This guide covers the how to find the best stops and hidden gems between cities approach, blending efficiency with discovery.

The historic core of Pécs was built on Roman foundations. The UNESCO-listed Early Christian Necropolis sits beneath the modern city. Leaving via Highway 57, you will soon see the M6 motorway, which connects to the M7 near the Croatian border. This first leg runs through flat Pannonian farmland.

Road quality is good throughout: Hungarian and Croatian motorways are modern; Austrian A2 and A9 are well-maintained but have long tunnel sections. The German A96 is two-lane in places and can be congested near Munich. Speed limits: 130 km/h in Hungary/Croatia, 130 in Austria (tunnel 100), 120 in Germany (often unlimited on autobahn but A96 has limits).

Plan rest stops every 2 hours. Key stops include: Breathe (Hungarian M7 service area) near Nagykanizsa; Ivanić-Grad (Croatian A3) with playgrounds; and Bad Radkersburg (Austrian A2) with picnic areas. For children, the Family+ stations in Austria offer indoor play zones.

• Carry cash for tolls and roadside market purchases.
• Pet-friendly: Many Austrian rest stops have dog walking areas; German Autohofs allow dogs inside cafes.
• Fatigue warning: The long A9 tunnel between Graz and Spielfeld has no mobile coverage for 10 km.

South of the border, Croatia’s Zagorje region offers gentle hills and vineyards. The A2 motorway cuts through valleys dotted with medieval castles. A short detour to Trakošćan Castle (exit 8) adds 15 minutes but rewards with a fairytale lake and tower views.

Slovenia appears briefly on the A2 corridor between Zagreb and the Austrian border. The stretch bypasses Maribor but provides glimpses of the Pohorje mountains. Local farm stands sell pumpkin seed oil, a regional specialty.

Eastern Austria’s A2 runs through the thermal spa belt. Bad Gleichenberg and Stegersbach are known for their thermal waters. The landscape shifts from rolling hills to the foothills of the Alps near Graz. After Graz, the A9 climbs through the Gesäuse mountains, a limestone canyon with dramatic cliffs.

In Germany, the Allgäu region presents alpine pastures and dairy farms. The A96 highway skirts the northern edge of the Alps. Local commercial activity centers on dairy products, beer, and woodcraft. Markets in Memmingen and Wangen sell fresh cheese and cured meats.

The fastest path uses highways: M6/M7 in Hungary, A3 and A2 in Croatia, A2/A9 in Austria, and A96/A98 in Germany. Tolls apply in all countries. A vignette is needed for Hungary (pay online or at border), Croatia (electronic toll via ENC or manual), and Austria (vignette purchased at gas stations). Germany has no vignette for cars.

Fuel prices vary: Hungary and Croatia are competitive, Austria is higher, and Germany tends to be the priciest. Plan to fill up in Hungary or Northern Croatia to save. The route passes several large fuel stations near motorway exits, but rural sections have fewer options.

• Hungary vignette: 10-day pass ~€15.50
• Croatian tolls: ~€25 for 200 km
• Austrian vignette: 10-day pass ~€9.90
• Total estimated toll cost: ~€50–60
