Cahokia Mounds preserves 70 of the original 120 earthen mounds built by pre-historic Native Americans. Visitors may climb a stairway to the top of Monks Mound, where interpretive signs provide an explanation of the impressive view. Other physical features include a reconstructed stockade wall and “Woodhenge,” a circle of posts around a large central post from which the sunrise can be aligned to determine the season and time of year. Prairie grasses at several locations offer glimpses of native area vegetation. The site also has a day-use area with picnic shelters.
The Interpretive Center houses museum exhibit galleries, a life-size village recreation, an orientation show theater, a public programming auditorium, museum shop, snack machines, public restrooms, staff offices, and a courtyard for educational programs. Programs at Cahokia Mounds are organized around the Interpretive Center. Exhibit galleries and an award-winning orientation show, “City of the Sun,” describe the Native Americans of the Mississippian cultural tradition who lived there as well as the site’s historic and archeological significance. A “mural walk” booklet explaining the exhibit gallery murals is available for loan at the information desk. The Interpretive Center is accessible to persons with disabilities, as ae some of the trails.
The Interpretive Center is open Wednesday through Sunday from 9 am to 5 pm, and closed Mondays and Tuesdays (except Memorial Day and Labor Day when it is open). The grounds are open every day from 8 am to dusk. During June, July and August, guided tours are offered Wednesday through Saturday at 10:30 and 2:30, and on Sundays at 12:30 and 2:30. In April and May, and in September and October, guided tours are offered on Saturdays and Sundays at 2:30. Self-guided tours are available year round through the free loan of a cassette player, the purchase of a guidebook in the Gift Shop for $1, or the rental of iPod Touch units for $3 through the Gift Shop. All of these include the three outside interpretive trails.
Along the Plaza, Monks Mound, and Woodhenge trails visitors can view some of the site’s most significant historic and archeological features. Cassette tapes and guidebooks to these trails may be obtained at the Interpretive Center. Both are available in several languages, and the guidebook is also available in Braille.
A 6.2-mile Nature/Culture Trail passes through more remote areas, which include various wetland, forest, and grassland environments, and the mile-long Prairie State Nature Walk features flora and fauna of the area. Booklets relating to these trails may be obtained at the Interpretive Center.
The site hosts a number of special events, including a series of scholarly lectures, storytelling days, summer field schools, annual equinox and solstice observances, “Kids’ Day,” "Archaeology Day," a “Native Harvest Festival,” and three art shows featuring American Indian artists. Contact the site for details. The Cahokia Mounds Museum Society support group funds the site programs through operation of the Interpretive Center Museum Shop, a membership program, and grants.
