The water treading area is very well maintained! Be careful, the two steps covered in water are a bit slippery. Have fun!

The Hohle Stein (Hollow Stone) is located in the middle of the Tobel Gorge. It was eroded over millennia and is now a monument to erosion. A small amount of water trickles down from the ceiling of the small grotto throughout the year.

Below Spiegelberg-Jux, siliceous sandstone has been mined since the Middle Ages and processed into whetstones for sharpening scythes. The Wetzsteinstollen visitor mine is a silent witness to this era, in which – uniquely in Europe – whetstone-grade material was mined in a mine. See also: http://www.wetzsteinstollen.de/
