If only the ageing walls of Schloss Neudau could talk! But seeing they can't, check if tours are available to hear a couple of its stories instead.
You're spoiled for sightseeing choice when staying in Neudau. Schloss Neudau is a great place to start here, but there are loads of other worthy spots to appreciate. Therme Bad Blumau, H2O Hotel-Therme, and Heiltherme Bad Waltersdorf are close to the fortified complex and will top off your day nicely.
