River Bluff-Effigy Tumuli Trails
River Bluff-Effigy Tumuli Trails in Buffalo Rock State Park offers a unique hiking experience high above the Illinois River and around the massive earthen sculptures of the Effigy Tumuli. Clocking in at 3-miles this easy to moderate hike will be a sight you’ll want to see. The River Bluff Trail is a great way to experience the Buffalo Rock landscape. Buffalo Rock sits like a sandstone island above the surrounding land and Illinois River. The park features oak and hickory woodlands and an expanse of restored grassland where the Effigy Tumuli rise.
