Illinois is often dismissed as a land of flat cornfields and urban sprawl, but travelers who take to the open road in an RV soon discover a state rich in geographic variety, historic highways, and dense natural beauty.
From the rolling glaciated hills of the north down to the ancient sandstone bluffs of the south, Illinois offers some of the most scenic road trips in the Midwest.
Whether you are seeking a quick weekend escape or an extended cross-state expedition, these top routes and destinations highlight the very best of RV travel in the Prairie State.
1. The Great River Road: Following the Mighty Mississippi
Stretching over 550 miles along the western border of Illinois, the Great River Road is widely considered one of the premier scenic drives in the nation. Following the path of the Mississippi River, this route takes travelers past steep limestone cliffs, historic river towns, and sweeping vistas.
Starting in the far northwest corner of the state, Galena is a mandatory first stop. This storybook town boasts preserved 19th-century architecture, boutique shopping, and nearby RV parks tucked into the rolling terrain. Further south along the drive lies Mississippi Palisades State Park, where dramatic bluffs tower over the river, offering spectacular hiking trails and prime bald eagle watching.
As you continue south, the route merges into the Meeting of the Great Rivers Scenic Route near Alton. Here, the Mississippi, Missouri, and Illinois Rivers converge in a magnificent floodplain ecosystem. Pere Marquette State Park serves as the ideal basecamp for this section, providing spacious RV campsites with full hookups surrounded by lush forests.
2. Historic Route 66: Nostalgia on the Open Highway
For lovers of Americana, no RV trip compares to driving Illinois' 300-mile stretch of Historic Route 66. Beginning in downtown Chicago and winding southwest toward the Missouri border, the Mother Road is a journey back in time.
The route is packed with retro roadside attractions, classic neon signs, and historic diners. Major stops along the path include Joliet, Pontiac, Bloomington, and Springfield. In Springfield, RVers can immerse themselves in American history by visiting the Abraham Lincoln Presidential Library and Museum alongside historic sites dedicated to the nation's 16th president.
Several well-equipped RV parks line the route, offering convenient access to interstate bypasses while allowing you to step right onto the historic two-lane highway whenever you choose.
3. Starved Rock State Park and the Illinois River Road
Located in north-central Illinois, the Illinois River Road Scenic Byway offers a peaceful route through river bottoms, agricultural heartlands, and striking geological formations. The star attraction of this corridor is Starved Rock State Park.
Famous for its 18 deep, spring-fed canyons carved by glacial meltwater, Starved Rock feels worlds away from the flat prairies nearby. Springtime trips yield flowing waterfalls in canyons like St. Louis and French Canyon, while autumn brings brilliant forest foliage.
The state park campground features electric hookups, bathhouses, and paved sites suitable for rigs of various sizes. Right next door, Matthiessen State Park offers additional canyon hikes and prairie views with far fewer crowds.
4. Shawnee National Forest: The Southern Wilderness
Driving south toward the tip of the state reveals a dramatic landscape transformation. Southern Illinois is defined by the Shawnee National Forest, a region of rugged hills, dense hardwoods, and prehistoric rock formations.
The crown jewel of this region is the Garden of the Gods Recreation Area. Perched high above the canopy, massive sandstone rock formations sculpted by millions of years of wind and rain offer panoramic views that stretch for miles. Nearby, Giant City State Park features towering rock structures that resemble city streets, along with excellent RV campgrounds offering full hookups and shady sites.
The region is also famous for the Shawnee Hills Wine Trail, allowing RV travelers to combine outdoor adventure with visits to local vineyards and artisan shops.
Tips for RVing in Illinois
Planning ahead ensures a smooth trip through the Prairie State:
- Seasonality Matters: The ideal window for RV travel in Illinois runs from mid-May through October. Spring offers roaring waterfalls at Starved Rock, while autumn brings crisp air and peak fall colors in the Shawnee National Forest.
- State Park Reservations: Illinois state parks use centralized online reservation systems. Top destinations like Starved Rock, Pere Marquette, and Illinois Beach fill up months in advance for summer weekends, so book early.
- Navigating Around Cities: While rural highways are smooth and easy to navigate with large rigs, watch for low-clearance bridges in small towns and avoid pulling large trailers into downtown Chicago traffic.
