There are no overnight accommodations within the park itself. To protect the archeological site, camping is never allowed.
There are over a dozen hotels in nearby Collinsville, Caseyville, and Fairview Heights, IL. St. Louis is very close with its many hotels.
Camping is available at nearby Horseshoe Lake State Park, 2 mi 3 km. Several private campgrounds and RV parks in Granite City and Fairmont City also offer nearby accommodations.
