You only see what you know (Goethe)
Along a gorge next to Millstatt there is a fun trail (Klangschlucht Millstatt) which invites hikers to listen to the sounds of the gorge and the water. At this waterfall I was impressed to hear two completely different sounds: The roar of the waterfall and the gurgle of the brook named Riegenbach at the same time.
The Breitachklamm is a gorge located in Allgäu next to the border between Germany and Austria. On the German end of the gorge there is a helpful exhibition hall explaining the different parts of the gorge and how such a gorge come into being.
The trail along the Mendlingtal is a path of about 3 kilometres. It leads from a theme park about logging up to a former Hammerherrenhaus (Home of the owner of a hammer mill). The scenery is changing several times. Sometimes one walk along a tame creek, sometimes one walk along footbridges high over a stream in full spate.
