Wildweiberhäuschen, Protected area in Haiger, Germany

Wildweiberhäuschen is a nature reserve in Langenaubach near Haiger that protects creek meadows, species-rich tall herb communities, and deciduous woodlands across roughly 23 hectares. Alongside the meadows along Aubach creek, the old limestone rock formations with their caves and the surrounding maple, ash, and alder forests define the character of the reserve.

The limestone cliffs formed roughly 360 million years ago in an ancient ocean and were later exposed through erosion. Researchers found bones of cave bears and reindeer inside the caves, showing that animals used the rock shelter during the Ice Age.

The reserve and its limestone crag take their name from the Wildweiberhäuschen rock, a name tied in local storytelling to wild women said to dwell in the forest. The two natural caves in the rock have yielded finds from the Old Stone Age to the Middle Ages, linking the name to the area's long human history.

The reserve lies on the southern edge of Langenaubach between Aubach creek and the K41 road toward Breitscheid and can be explored along a loop trail. The paths pass through wet terrain with meadows and forests, so sturdy footwear and some time for observing nature are recommended.

The rock's two natural caves yielded bones of cave bears, reindeer, and ptarmigans, along with traces of human presence from the Old Stone Age to the Middle Ages. A former tunnel in the rock now serves as a winter roost for bats, including the greater mouse-eared bat and Daubenton's bat.
