Kesselfallklamm
The countryside immediately around Graz is wild and romantic. Among the natural attractions hidden away here are narrow gorges and gullies, through which busy streams rush. The beautiful Kesselfallklamm is like a little sister to the mighty Bärenschützklamm. Well secured steps allow you to explore this romantic gully comfortably with children too. At its northern end is the town of Semriach, a health resort popular for its air quality and treasured as a wonderful patch of Styria.
