Hohenhewen Castle

Highlight • Castle

A hike to the Hohenhewen castle ruins is worthwhile just for the wonderful view. A viewing platform was built onto the rest of the keep, from which you can see the Hegau mountains, Lake Constance and the Swabian Alb to the north. In good weather and with a clear view, you can also see the Alps and the Black Forest.

Höwenegg Crater Lake

Highlight • Lake

Also called the "Blue Eye" of the Hegau.
Unlike other volcanic relics and maars in the Swabian Alb, the "Höwenegg" is part of the Hegau volcanism. The main crater is the largest of a total of six eruption sites from which basalt and basalt tuff were mined. The lake visible today was formed in the former mining area.
The eruption occurred 10 million years ago. At that time, a crater lake formed, which was visited by numerous animals. Fossil finds of 13 prehistoric horses, antelopes, and rhinos attest to the subtropical climate at that time. The fossils were excellently preserved in the lake sediment.

Danube Sinkhole

Highlight • Natural Monument

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.
