In the Devil's Cave near Kremsmünster, people often saw oddly shaped dishes, but never got around to them. A student who tried it was difficult to find. Children who picked strawberries were once startled by heavy "sledding" underfoot. Also Flammchen should have flown around the cave. 100 years ago, one still showed the stone into which the devil had pressed his "claws".
The devil's cave is washed out of conglomerate (Nagelfluh?) Rock. In winter absolutely worth seeing ice formations. But even in summer offer the Teufelshöhlen worth seeing.
The "waterfall" that overcomes a conglomerate level (seen here as a large "icicle") is a sintered foot in summer (tufa).
Attention in the summer here are a lot of spiders frolic. So not for people with arachnophobia :-).
