Prairie State Park

Park Information

Tallgrass prairies once covered more than a third of Missouri; today, less than 1% remains, much of it preserved at Prairie State Park. Visitors to the park see panoramic vistas of swaying grass and ever-changing wildflowers. They also may spot the park’s resident bison herd. The park’s Regal Tallgrass Prairie Nature Center offers exhibits and interpretive programs designed to inform visitors about the special place.
