Cheap for a private campground, nice man-made swimming pond, cool history
I've been going to this campground my whole life. My grandparents used to have a permanent site here and we've been going here every labor weekend since I was born (I'm currently 25). There have nice grassy sites with tall trees for partial shade.
A few years ago they tore out the old small swimming pool and put in a large chemically treated swimming pond. The swimming is pretty good and there is now plenty of space. The only possible downside with small children, as there is no fence around the pond, and there are sites that border the pond.
It is fun to go down by the river and explore. One year we caught about 60 crayfish and cooked them on the campstove and ate them.
Sometimes they also give a tour of the old mill that is on the grounds. There is a lot of history. Also, if you are into caving, the Maribel caves are only a mile down the road.
