Hundekehlefenn

Hundekehlefenn is a protected natural area in Berlin's Charlottenburg-Wilmersdorf district that features wetland habitats stretching between lakes and streams. The terrain displays a mosaic of reed beds, marsh forests, and open water surfaces with varying elevations and plant communities.

The area received official protection status in 1960, marking the start of systematic nature conservation efforts in the Grunewald forest. This designation was part of broader attempts to preserve Berlin's remaining natural woodlands for future generations.

The name comes from Lower German, where 'Fenn' means a marshy inland lake and reflects medieval Flemish settlement patterns. This linguistic heritage remains visible in how locals and visitors understand the landscape today.

The area is accessible via several marked hiking trails that offer different lengths and difficulty levels. Visitors should wear sturdy footwear, as the soggy ground can become muddy, especially after rain.

The reserve contains mesotrophic marsh ponds and ancient alder swamp forests that rank among Berlin's last original plant communities. These rare forest types are seldom found elsewhere in the city today.
