The Upstallfließ is one of several streams and flows into the Hellsee. Here it still bobs over beautiful meadows and shortly before the mouth it becomes rather swampy.

Unfortunately, access to the shore area is largely blocked by a wire fence. Serves to protect nature. Please note. At the end of the fence there is a small entrance for interested hikers at the beaver dam. Nice photo motif.

Swampy section within the former castle park. There used to be a large meadow here, which has now turned into an alder swamp forest.
