I'd seen a lot of great reviews for this campground, so I had high expectations when we arrived for a night in early November. We reserved a spot in the 900 loop, just to be safe - a few of the camping loops allow reservations, and the rest are walk in. The loop was very open, spaces all fully visible to each other. The bathrooms were locked for the season after 10/15.
Since things were pretty empty, we moved to the 500 loop, which was more tree covered, near the river, and next to the shower house, which was the one park bath open for the winter. Bathrooms and showers were clean, though no camp host was present the night we stayed.
We were the only people on the 500 loop, so it was fine, but again - sites VERY close together. Some picnic tables were less than 20 feet apart. The 600 loop was the only heavily occupied loop when were there, filled with campers, presumably because of the electric access.
This is a NPS campground, so its amenities tend to be fewer than many MO state parks. I have other parks in this area that have more scenic and private tent camping. Just on the other side of the river is the Alley spring and mill, which are lovely - and ironically, some of the picnic sites are more spacious than these tent sites. I wish we could camp on that side!
