Camping here is great. The sites are large, clean and well kept. Privacy is good. There don't seem to be any raccoons, and mosquitos aren't bad. Park rangers are very polite and helpful. Fire rings are in very good condition and have excellent cooking grates on them.
Fishing is good for small children. The big pond is very weedy, but teeming with bluegills that are too small to keep. It's hard to not catch them.
The hiking trails are nice, but none are very long. They are fairly scenic, this part of the Kettle Moraine is very nice.
