Bad Radkersburg sits at the Austrian-Slovenian border on the Mur river, where a medieval bridge once carried the main trade route between the Adriatic and the Danube. The 13th-century town grid remains intact, making the Hauptplatz one of Styria's best-preserved Renaissance squares. The Parktherme thermal spa taps the geothermal belt that runs through southeastern Styria into Slovenia. The Murradweg cycle path passes through the town. For travelers exploring the South Styrian wine region or crossing into Slovenia, Bad Radkersburg offers an unusually layered stop. About 1.5 hours from Graz by car.
