Pokagon State Park is one of the most manicured , well maintained parks I've been to. The Army Corp does some good work but Pokagon has them beat.
One of the differences is that it doesn't seem like I hardly ever see any of the Corp workers , but at Pokagon the staff was right there doing their thing, registering, guiding, informing, mowing and maintaining.
The campgrounds are well laid out with several different areas to choose from. There were several youth groups at the group campground but you could not hear them from the other campground. The sites are well spaced and provide privacy if you want it plus room for extra tents or shelters. The facilities are maintained and clean.
There is an extensive trail system to enjoy that connects with the nearby nature preserve. There are horse tours and a very nice Inn for the less "natural" crowd.
