"Experience Seewiese campsite in Mammern - a charming family-run business by the Untersee. Enjoy direct access to the lake, cozy permanent and visitor spots, and a convenient small kiosk. Explore the nearby farm shops and bask in the scenic surroundings."
This campground has very clean toilets and showers. It is mainly occupied by long-term campers, but there are a few spots for campers and vans. They also have a small petrol station that sells local groceries. The staff is friendly and the check-in process is easy. There is a private access to a lake and a small but nice kiosk.
We felt comfortable during our stay at a place with clean sanitary facilities. We made a reservation in advance.
