Illini State Park Access provides a boat ramp and dock on the Illinois River near Marseilles, making it convenient for launching boats and kayaks.

The park offers 100 campsites with electric hookups (30/50 amp), a dump station, and facilities including showers and flush toilets, though water and sewer hookups are not available at individual sites.

Affordable camping rates ($10-$30/night) and riverside picnic areas make this a practical base for fishing and paddling on the Illinois River, with the added benefit of watching barge traffic through the nearby Marseilles Locks.
