This somewhat bumpy path leads through beautiful nature between Marienstedt and Groß Zecher. Coming from Marienstedt, turn right from the "Am Tiergarten/Zuckerhut" road onto the narrow path, reaching Schaalsee, and from there continue to Groß Zecher via the campsite, which is beautifully situated directly on the lake. A beautiful route that I would like to recommend.
Current update 6/27/25: The path has become quite overgrown and very narrow, but is still passable.
