Illinois runs a long way from the Wisconsin line to the Ohio River, and an RV trip here usually means choosing an end. The north has Chicago, Lake Michigan and a cluster of natural lakes. The middle has sandstone canyons on the Illinois River and Lincoln sites in Springfield. The south has river bluffs and the Shawnee National Forest. State parks with electric campsites are spread along the whole route.
Before you plan: RVRents does not deliver, set up or service RVs in Illinois yet. You can rent today from RV owners listed on Outdoorsy, and you can join the waitlist for RVRents service in Illinois. This guide covers regions, campgrounds, reservations and the tolls and roads that matter for an RV.
How Illinois Breaks Down for RV Travel
Chicagoland and the northeast covers the city, the Lake Michigan shore and the Chain O'Lakes. Northwest Illinois follows the Mississippi River bluffs near Savanna and Galena. The Illinois River valley runs southwest from Starved Rock to the river's meeting with the Mississippi near Grafton. Central Illinois is farm country around Springfield. Southern Illinois is hillier and wooded, with the Shawnee National Forest and Giant City State Park near Carbondale.
Top RV Destinations in Illinois
Chicago and the North Shore
Plan to visit the city as a day trip and camp outside it. Adeline Jay Geo-Karis Illinois Beach State Park, on Lake Michigan near the Wisconsin line, has 220 Class A Premium sites with electricity in its southern unit, open April 1 through November 15. Sites have no individual water or sewer hookups, but the park lists water hydrants throughout and a dump station at the front.
Chain O'Lakes
Chain O'Lakes State Park, in McHenry and Lake counties, borders three natural lakes and the Fox River, which links seven more. IDNR describes the chain as nearly 6,500 acres of water with 488 miles of shoreline, so this is a boating and fishing base. The park has Class A Premium and Class B Premium camping areas. Check the park's camping page for notices about construction work before you book.
Starved Rock and Utica
Starved Rock was the state's second state park, established in 1911. It has 18 sandstone canyons along the Illinois River and more than 13 miles of trails to waterfalls and overlooks. The campground requires reservations, taken online only, 6 months to 4 days before arrival. The park says it fills quickly, with May through October weekends going first, and each site allows 2 tents or 1 RV and 1 tent.
Kankakee River
Kankakee River State Park, south of the Chicago suburbs, gives you a river campground for a weekend out of the city. Its Potawatomi Campground is Class A, with showers and electricity, and the Chippewa Campgrounds have electric-only and primitive sites. An Emerald Ash Borer quarantine applies in Kankakee County, so no firewood can come into or leave the park.
Savanna and Galena
Northwest Illinois sits in unglaciated terrain, with steep bluffs over the Mississippi. Mississippi Palisades State Park, 3 miles north of Savanna, has 241 Class A and B sites, with electrical hookups at 110 of them and two sanitary dump stations. It is a reasonable base for Galena, where the U.S. Grant Home is a state historic site with costumed interpreters from April through October.
Springfield
Springfield is the Lincoln stop. Lincoln Home National Historic Site has a bus and RV lot north of the visitor center, but the National Park Service says it is often full in April, May and October, and overnight parking is not allowed. For camping, Sangchris Lake State Park is east of the city, with Class A electric sites and a dump station in each campground.
Grafton and the River Road
Pere Marquette State Park, on the Illinois River near Grafton, has bluffs of wind-blown loess soil you can see along its roads and trails. Its Class A campground is the one for electric and RV camping. The park takes reservations up to 180 days ahead, and they must be made at least three days before arrival.
Carbondale and the Shawnee National Forest
Southern Illinois is the state's hill country. Giant City State Park, near Carbondale and within the Shawnee National Forest, is known for the "Giant City Streets," sandstone bluffs along its nature trail. Its Class A campground has 85 sites with water, electricity and showers for tent and trailer camping. Garden of the Gods, in the Shawnee, is a strong day trip for its quarter-mile Observation Trail past Camel Rock and other sandstone formations. Its Pharaoh Campground has only 12 sites, and the Forest Service gives no trailer guidance for it.

Camping and Reservations
The Illinois Department of Natural Resources books all of its campsites through ExploreMoreIL, paying by Visa, MasterCard or Discover. The rules worth knowing: reservations must be made at least three days before you need the site, you can reserve a maximum of 14 nights within a 30-day period, and Memorial Day, Labor Day and some Fourth of July weekends require a two-night minimum. IDNR says most campsites can be reserved from May 1 through October 31. Booking windows vary by park: Illinois Beach and Pere Marquette list 180 days, and Starved Rock lists 6 months.
IDNR uses class letters for its campsites. Class A sites have electricity and showers. Other classes, such as B and C, offer fewer services, and the mix differs by park. For an RV that needs power, look for Class A or an electric class on the park's listing.
In the Shawnee National Forest, the Forest Service camping page lists each campground. Some are small: Pharaoh Campground at Garden of the Gods has 12 sites and does not take reservations.
Driving an RV in Illinois
Tollways. The Illinois Tollway serves the Chicago region and northern Illinois. Its 2026 rate sheets describe the plazas as cashless, with cash not accepted. I-PASS and E-ZPass transponders are charged automatically. Without one, use Pay By Plate within 14 days of your first day of travel, and your card is charged the cash rate. Pay By Plate does not cover the Chicago Skyway, which is not part of the Illinois Tollway. In a rented RV, ask the owner whether a transponder is on the vehicle before you set up Pay By Plate, so you are not charged twice.
Speed limits. The Secretary of State's 2026 Rules of the Road lists 70 mph on interstates and tollways and 55 mph on other highways, unless posted otherwise. Watch for lower posted limits, especially in urban areas.
Road conditions. IDOT runs the state highway system and posts road conditions and construction at Getting Around Illinois. Check it before winter drives and through the summer construction season.
Worth knowing: Starved Rock takes reservations only online, from 6 months to 4 days before arrival, and the park asks you not to call to cancel. If you want a summer weekend there, put the date 6 months out on your calendar. If it is already full, Kankakee River and Illinois Beach are the usual fallbacks within reach of Chicago.
Seasons and Weather
Late spring through early fall is the main RV season, and it lines up with IDNR's May through October reservation window. Fall color in the river bluffs and the Shawnee makes October a strong month. Summers can be hot and humid, and spring and summer bring severe thunderstorms, so keep an eye on watches and warnings. Winters are cold, and many shower buildings close: Sangchris Lake, for example, shuts its water facilities from the Monday before Thanksgiving through March 31, and Starved Rock's East Loop closes from the weekend before Thanksgiving to April 1. Check weather.gov for current forecasts and alerts.
If, then
- If you are starting in Chicago and want a lake weekend, book Illinois Beach or Chain O'Lakes.
- If you want canyons and waterfalls, plan Starved Rock and book 6 months ahead.
- If you want Lincoln sites, camp at Sangchris Lake and arrive in Springfield early to find RV parking.
- If you want hills and forest, base at Giant City and day trip to Garden of the Gods.
- If your RV has no transponder, set up Pay By Plate within 14 days of using the Tollway.
