The seaside resort at the Haldensee is an ideal starting point for hikes and bike tours. There is plenty of parking (subject to charge, max 5 € / d). The bathroom opens from 10:00.
In good weather, it can be very crowded during the day and easily chaotic on the surrounding paths. German tourists in particular also like to lose their nerves.
The campsite offers gravel parking for caravans and a meadow for tents. As a camper with tent but you have no parking directly at the tent. You can park in the parking lot of the bath - nobody controls the tickets either ...
The restaurant is basically ok. Beer on tap, fresh coffee crema. The food is v. A. from the deep fryer. From 17:00 the kitchen is closed, from 18:00 the restaurant is closed.
