This is a very small but interesting park for nature lovers or history buffs. The indian ceremonial structures are among the largest in the US, though the old walls have declined in prominence over the centuries. Trails run along the river and are very enjoyable, with several access points where you can see waterfalls or play in shallow water if you so desire. The less traveled yellow and red trail extensions were surprisingly beautiful and we had them mostly to ourselves.
We stayed for a couple nights in the campground. It was generally enjoyable, with a couple caveats. Although the sites vary in size, most are heavily wooded and provide partial or full shade. All sites have electric and water and there is an older bathing facility with hot showers.
Upkeep at the campground was average at best. We arrived mid-day on Friday, stayed all day Saturday, and a half day Sunday. At no time during those three days did the men's restroom in the campground have paper towels. Yet, we saw park maintenance employees constantly in the campground on Friday afternoon. There were also lots of rangers about, but the camping office was closed every time we passed it for the entire weekend. The concrete pads around the picnic tables had thick mud caked under the tables, making it pretty apparent that the employees rarely if ever bother to clean the sites. Although there seem to be a lot of employees, perhaps they could be put to better use.
Overall, we enjoyed our stay despite the few irritations. This is a small park, best enjoyed with a short visit. You can do justice to the archeology in just a couple hours, and there's enough hiking to keep you busy for a day, if you look for it. Though the Duck River runs through the park, it isn't really very accessible for canoes or kayaks. Beyond a day or so, I would seek out a larger park with more to do. (Fall Creek Falls comes to mind). This is Tennessee, so if you don't enjoy the heat, the best time to visit would be spring or fall.
