Things to Do in Cahokia Mounds
Cahokia Mounds is more than a museum stop, it’s a 2,200-acre historic site with earthworks, trails, a reconstructed solar calendar, and enough ground to cover that most visitors spend a half day or more here. Beyond the Interpretive Center, here’s what there is to see and do on-site.
Climb Monks Mound
Monks Mound is the largest earthwork in North America, and a stairway leads to the top. From up there, you get a wide view back toward the St. Louis skyline, one of the best photo opportunities at the site. The mound and its stairway are outdoors, so they’re accessible daily, dawn to dusk, regardless of the Interpretive Center’s hours.
Walk the Trails
Cahokia Mounds has trail options for different paces and interests:
- The 3.5-mile loop trail winds through the site and is popular for birding and hiking. It’s dog-friendly on a leash and open year-round.
- A shorter, 3/4-mile paved loop is available for visitors who want an easier, fully accessible walk, flat and concrete, with benches along the way.
Both give you a closer look at the mounds beyond what you can see from the parking lot or Interpretive Center windows.
See Woodhenge
Woodhenge is a reconstructed circle of wooden posts that ancient Cahokians used as a solar calendar, aligning sunrise positions to track the seasons. It’s a quieter, less-visited part of the site, but a meaningful one if you’re interested in how sophisticated the original city’s astronomy and planning really were.
If you can time your visit around an equinox or solstice, the site occasionally hosts sunrise observance events at Woodhenge, worth checking the current events calendar before you go, since dates shift year to year.
Picnic Grounds
If you want to make a full day of it, picnic tables are available about half a mile from the Interpretive Center, first-come-first-served. It’s a good stopping point between the mounds and the trails.
Tips for Your Visit
- Wear comfortable shoes, the mound climb and trails involve real walking.
- Bring water, sunscreen, and insect repellent, especially in warmer months.
