Campgrounds and RV parks near Downers Grove, IL

Downers Grove sits in DuPage County about 22 miles west of downtown Chicago, at the intersection of I-355, I-88, and I-55. That location puts renters within a short drive of forest-preserve campgrounds, lakeside private resorts, and larger destination RV parks along the I-80 corridor south of the city. The area is flat, heavily developed, and best suited to RVers who want an urban-adjacent base rather than remote wilderness camping. Closest options include Martin Campground and Pingala RV Resort, followed by Chicagoland Speedway/Lakeside Campgrounds and Hollywood Casino Hotel and RV Resort near Joliet, both useful for race weekends and casino stays. Leisure Lake Membership Resort offers a lake-oriented experience farther out but remains within reasonable towing distance. Renters should expect a mix of full-hookup private resorts and electric-only public campgrounds. Forest-preserve sites in DuPage and Cook counties provide the closest natural settings, while state parks with camping, including Starved Rock and Illinois Beach, sit roughly 60 to 90 minutes away and require advance planning.

Illinois state park campsites are booked through the ExploreMoreIL system at camp.exploremoreil.com. The window opens six months before arrival and closes three days out, at which point remaining sites move to walk-in. A non-refundable reservation fee applies, and the maximum stay is 14 nights. DuPage County forest-preserve camping at Blackwell is permitted through the district's online system up to a year in advance, and reservations must be finalized at least three full business days before arrival. Cook County sites are booked through fpdcc.com. Private resorts near Downers Grove, including Martin Campground, Pingala RV Resort, Chicagoland Speedway/Lakeside Campgrounds, Hollywood Casino Hotel and RV Resort, and Leisure Lake Membership Resort, are booked directly with each property. Race weekends, holiday weekends, and midsummer dates fill first, so renters should lock in dates well ahead of travel.
