Illini State Park is the kind of park you think of when you think of big picnics and family gatherings. With its rustic Civilian Conservation Corps buildings and riverside picnic areas, Illini State Park offers beautiful views and a sense of history not found in many other parks. Named for the native Americans who once inhabited the area, Illini State Park is located south of the Illinois River from Marseilles and U.S. Route 6. The northern edge of the 510-acre park is bordered by the Great Falls of the Illinois River. In just two miles, the river drops three feet, creating beautiful roaring rapids. The east end of the park is the former site of the prestigious Marsatawa Country Club.
