You can see the wine hills of the Seggau castle from afar and you know: this is a wine-region. Leibnitz is the pivotal point of the Sudsteirisch wineland: the city offers great outdoor cafes with both local and international dishes and of course many steirisch wines. Many events take place in town: of course wine celebrations but also sport, music and cultural events.
Great shopping, good accommodation, the Sulmflussbad for swimming are recreation and many places nearby where you can make excellent hikes make this a good place to stay a while. Highlights include a hike to the ruins of Flavia Solva or a walk on the Weinlehrpfad of the local wine makers school.
