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.

View of the Charlottenhöhle and the valley

Highlight • Viewpoint

This rather unknown viewpoint can be found directly above the Charlottenhöhle in Hürben and offers a wonderful view of the cave house and the valley.
Caution is advised as there is a risk of falling.
The viewpoint can be reached from the Charlottenhöhle hiking trail and by bike from Reuendorf or Hürben sports field.
Accessible on foot and by mountain bike.
