Boone, Iowa

For the proximity to Boone, I wouldn't let the bathrooms/showers scare you away. There are two bathhouses, one in the electric loop, and the other in the tent loop. They are your typical state park bathrooms, in need of renovation, but not intolerable.

There is a lot of hiking/exploring to do in Ledges, that can take most of a day. Ledges has a limited number of electric sites - finding weekend sites can be a challenge. I would look at reservations.
