    Tips

    On most days of the year, the Danube "disappears" completely. Due to the water-soluble limestone, an "underground river" has formed. The water flows invisibly away and reappears at the 12 km distant Aachtopf (the largest karst spring in Germany). From there it flows as Radolfzeller Aach to Lake Constance. The Danube water becomes Rhine water.

      Depending on the season and precipitation, you can explore the riverbed to different extents and admire the occasional "cairn".

      The term seepage is somewhat misleading, since the Danube does not seep away, i.e. the water is distributed in the ground, but flows into underground cavities and therefore, strictly speaking, represents a sinking.
