I stayed at Union Grove State Park twice over the course of my 4-year stint in Iowa. It's probably one of my least favorite state parks for many reasons.
First of all, the terrain is really boring. Well, Bradley, it's Iowa, and boring is what Iowa does best! Not so, I decry! There are some spectacular state parks in Iowa that are anything but!

Anyway, beyond the boring terrain, the campsites here were rocky, sloped, and generally uncomfortable. I don't think the fees were too outlandish, but jeez, the fact that they even charge a fee here seems like too much to pay.
They do have some good fishing here, supposedly. If that's your thing, yay? read more
