Searched for camping with SupWater and came across this one. I did think it was a bit expensive (82 euros 3 nights with electricity 1 adult 1 child small bus camper on camper place). Not all showers work equally well. We cycled and sailed nicely. The lake is home to many nice critters such as grouse, carps, swans, beavers. Quiet in the evening and certainly worth walking around or sailing on.

Beautiful campsite with beautiful camper spots right on the lake. No shade. Sanitary fine, shower with coins (cost 50 cents). Friendly staff. Places directly on the water are more expensive, category 1. We paid €82 for 2 nights with a camper and 2 people including electricity, 4 shower coins and local tax. From the campsite you can make a nice walk of 13 km along 3 lakes. Despite the hefty price, it's definitely worth it.
