Illini State Park SignIllini 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.

Although the Illinois River rapids are wonderful to watch, they made barge traffic difficult. In the mid-1920s, the Army Corps of Engineers built a barge canal to bypass the rapids. The canal borders the park on the north, and visitors can watch as large barges pass by the park and through the Marseilles Locks.

The prestigious Marsatawa Country Club once graced the east end of the park. Organized by Ottawa resident W.D. Boyce, who also founded the Boy Scouts of America, the club boasted one of the premier golf courses of its day.

In the 1930s, two companies of the Civilian Conservation Corps converted the golf course to a park and built park buildings that are still in use today. The former country club building was moved into Marseilles and serves as the American Legion Hall.

The CCC camp at the west end of the park was converted into a semi-correctional boys’ camp that provided maintenance in the park until it was closed in the late 1960s.

Illini entered the state park system in 1934 and was dedicated in 1935.

Illinois Fallen Tree Memorial

At the far west end of Illini State Park, across a two and a half acre meadow, is a grove of 250 oak trees. Each tree celebrates the lives of Illinois soldiers lost in Iraq and Afghanistan. A natural granite monument stone weighing about seven tons was added to the site with a bronze memorial plaque memorializing these heroic Illinois soldiers.
