Bad Blumau is worth the trip from Graz for one reason: the Rogner Bad Blumau thermal spa, designed by Viennese artist Friedensreich Hundertwasser and completed in 1997. The complex is a full spa resort with accommodation, pools, and restaurants, unified under a design philosophy of no straight lines, grass roofs, and organic facades that make the building look like it grew rather than was built. The thermal waters come from a deep geothermal source and are genuine. Bad Blumau sits in the Steirisches Thermenland spa region of eastern Styria alongside Bad Waltersdorf and Loipersdorf. About 1 hour east of Graz by car.
