Illini State Park — RV Camping in Marseilles, IL

Illini State Park sits along the Illinois River in Marseilles, Illinois, offering 510 acres of natural beauty in the heart of the Illinois River Valley. Dedicated as a state park in 1935 and named for the Native Americans who once inhabited the region, the park features historic Civilian Conservation Corps buildings and sweeping views of the Marseilles Locks and barge canal. Campers enjoy 100 sites with electrical and water hookups, dump station access, toilets, picnic tables, and grills — with big rig-friendly accommodations available.
