Rest Area by the Brenz River

Highlight • River

It's very beautiful how quietly the Brenz flows. You can get into the water here; there's something like a fortified bank here.

Kaltenburg Ruins

Highlight • Castle

The castle dates from the early 12th century and came into the possession of the Counts of Helfenstein in the 14th century. After the castle was severely damaged in the Thirty Years War, it was only partially rebuilt. The ruins fell into disrepair and it was not until the 20th century that efforts were made to preserve the castle's condition. In the 1980s, large parts of the castle ruins were renovated and, above all, the two towers on the valley side were completely repaired.

In 2010 part of the defensive wall on the slope collapsed. The Kaltenburg-Verein organized a repair of the shield wall only with donations. The work was completed in the summer of 2018 and now the castle shines again in all its glory.
