They are also so beautiful throughout the seasons! Calamus Swamp offers a loop trail to enjoy the area. It is a combination of boardwalk, boards and chicken wire, dirt trail, and some creative use of logs to try to bridge muddy gaps. There's a great blind easily accessible via the grass to boardwalk trail, which lets you view the myriad of birds, insects, plants, and more that live in the area. We heard plenty of frogs plopping and singing as we walked by. A small parking area is available right off the road, with an informational kiosk of the swamp.

Had no idea this was here, and I've been visiting Chilly for 55 years. Of course, it wasn't a park…read moretill a few years ago, turns out; it was a farm. Large earthwork cluster, barely visible due to plowing but mowed so that they stand out now. Nice big park with decent parking, several trails, woods and wildflowers, and more. I can't hike like I used to but there is a fairly short trail from the parking lot to the main earthworks. If you are a history buff, or interested in Native culture, or just like nature and knowing about your town, this is a must-see. Chillicothe is full of history, recent and ancient, and it's cool to see more things like this being opened to the public.

Plan on walking around this location since the other locations the mounds have disappeared from centuries of traffic and plowing.

Small visitor's center that explains the culture, architecture and archaeology of the earthworks- Mound City is here, but there are several other properties in the area that are included in the National Historical Park. Baby K loved the Junior Ranger brochure, and learned quite a bit from it, the rangers, the movie, and my decrepit memory. We had family to see and it was sprinkling, otherwise we would have stayed longer than an hour. Figure on several hours if you really want to explore. We just missed the big culture gathering on October 14th. Oh, well. Still a fun and educational visit. We'll be back.

We did a loop using sections of Southpoint Lookout Trail, Blueberry Trail, and and Chilo Trail to head out and enjoy the view of the gorge and creek. The gorge contains some fascinating rock structures made from sandstone and shale. It looks like there are sometimes some waterfalls depending on rain, but they weren't flowing during our visit. We also checked out the Kids Nature Zone Trail, which was so fun! There were a variety of activities hidden out and about in the woods - fort building, stumps to jump/balance on, a seesaw, a swing over a stream, logs set up as balance beams over soggy sections, and more. A shelter house offers benches, picnic tables, and restrooms. The ranger was extremely friendly and chatted with us a bit about not only this preserve, but some of the other parks in Ross County when we ran into him. Great park!

I've been coming to Chillicothe for 50+ years, and have never been here. And never even really…read moreheard of it, although I've been to Mound City, and to smaller earthworks nearby. Apparently it just opened to the public recently. And it looks it. There is a sign out by 23, but that's about it. Drive a half mile back, and look for the little rest area on your right. That is it. There's a nice parking lot, lots of shade trees, a few picnic tables. People come and have lunch and bring their dogs to run around. If you want to see the earthworks, you are going to have to work for it. There are no signs. Go to the website, and look at the trail map. Go up that hill at the back of the parking lot, and follow the meandering mowed path through the fields. When you get to a much wider, perpendicular mowed area, turn right, and follow it to the powerlines and up that hill. Then turn left- at the top of that hill is the overlook. I didn't go quite that far. I climbed high enough that I could see the outline of what hadn't been mowed, And then I hiked back to the car. As the other reviewer said, it is easily half a mile from the road. They really really need to put in some signage. Both to find the parking lot and to find the earthworks. They could put in a half dozen signs along the trail, pointing you in the right direction, and providing a snippet of background information on each sign maybe. Then someday they need to put a parking lot much closer to the earthworks, and improve the paths. This is not set up for the casual visitor. And even for the history geek like me, it is a bit of a stretch. But, remember, there used to be earthworks all over this region, and very few are left. We preserve what we can, and try to learn from them.
