We passed by here on the way to Indian Cave. Honestly not sure if it's being used other than river access. By the parking lot for the boat ramp there were what appeared to be few primitive spots, and by the bathrooms there were a few hook ups. Really not much more than that.
Campground host was so friendly. I forgot my lighter and he rolled right over with a smoldering log in his dutch oven, so we were able to have a camp fire.
Nice little put in for boats. We camped right be the river and woke up to a beautiful sunrise. No more than a 1/2 mile outside the city, but still feels isolated. Great Lewis and Clark interactive museum and hiking about a 5 min drive away.
