We stayed in Nauvoo State Park with friends. We booked online and had picked backin sites. When we arrived the park was fairly empty so we moved to pull thru. I felt you might have trouble in long rigs getting around. The drives are not clearly marked and it was a little confusing! No modern facilities close and the pit toilets were very disgusting. It does have a shower house but we decided to just use ours. The town offers a lot of history. Did a little fishing but didn't catch anything. Lots of shade and mosquitoes! So bring plenty of spray.
We had never been to this Campground. We stayed in the Big Oak area. All sites are gravel and we didn't have any problems getting level. Our site was B-7 and friends were on B-5. Nice space and not crowded. The Campground seemed to be well taken care of. It was very quiet and we enjoyed our weekend. The problems were a broken water line a few years ago so no water in the upper Campground. The only bathrooms were pit toilets and the roofs need replaced on all of them. The shower house is out of commission because of the bad roof. We did find that the lower Campground area did have water.
