I stayed 4 nights at a campsite in the area. Absolutely fantastic! The people were lovely, and the campsite manager was super friendly. The food and drinks were really great. There's an Edeka supermarket with normal prices just a 10-minute walk away. Water, electricity, etc., are included at the campsite. Four nights for a family of four cost €134. What more could you want? The lake is a 2-minute walk away. Motorboats, pedal boats, and bicycles are all available for rent. We'll definitely be back!
