Košice to Thun Road Trip: Best Stops & Hidden Gems

This route from Košice to Thun spans over 1,200 km across Slovakia, Hungary, Austria, and Switzerland. A little-known fact: the section between Bratislava and Vienna is one of the shortest international highway stretches in Europe—just 65 km on the A4/E60.

The drive typically takes 12-14 hours without stops. However, with diverse landscapes, UNESCO sites, and culinary treasures, it's worth stretching to a multi-day trip. Use our how to find the best stops and hidden gems between cities guide to plan your journey.

The journey crosses the Carpathian Basin, the Hungarian Plain, the Vienna Basin, and finally the Swiss Alps. The most dramatic shift comes after Vienna, as flat farmland transforms into alpine foothills around Salzburg.
