This little camp ground is part of the Iowa River Trail system. There is a good sized parking / turn around area. It was well kept and it costs about $10 a night and is in Hardin County.
The gravel road is fairly busy, but it could just be due to planting season starting. There were quite a few annoying gnats / mosquito's. There is a ramp for access, but it is dirt and gravel, so not something you can back a boat down in there easily.
I spent a night here and it was a pleasant experience, other than the flying bug annoyances.
