Filsursprung, Karst spring in Wiesensteig, Germany
Filsursprung is a karst spring in the valley near Wiesensteig where water emerges from underground limestone formations. The water flows visibly through a pool before continuing downstream as a clear stream.
The spring originated as part of an ancient river network that shaped the valley and surrounding landscape over millennia. Limestone dissolution by water created the underground passages through which it now flows.
The source is known locally as a place where the water's emergence reveals the landscape's hidden water cycle. People visit to understand how the region's geology shapes what they see above ground.
The Papiermühle parking area offers a convenient starting point with clearly marked hiking paths leading to the spring. The trails are easy to follow and suitable for most visitors without special gear.
The water travels through hidden cave passages within the limestone before emerging at the surface, a journey that takes place entirely underground. This concealed network beneath the hills adds a sense of mystery to what you see above ground.
