Van Rentals in Illinois — Shawnee, Starved Rock, Great River Road
Most of Illinois is farmland, and then the bottom 10% of the state turns into sandstone canyon country nobody expects. Shawnee National Forest is the only place in Illinois with real dispersed camping, and Garden of the Gods looks like it belongs three states south. Coverage stages from Chicago, Springfield and the metro-east.
Where vans go
Public lands & camping in Illinois
Shawnee National Forest (southern Illinois)
289,000 acres — Garden of the Gods, the Lusk Creek Wilderness, and the state's only dispersed camping.
Starved Rock State Park (Utica)
Eighteen sandstone canyons with seasonal waterfalls; a designated campground and Illinois's busiest trails.
Mississippi Palisades State Park (Savanna)
Limestone bluffs above the Mississippi on the northwest corner of the state.
Midewin National Tallgrass Prairie
The first national tallgrass prairie, on a former arsenal south of Joliet; day use, bison herd, no camping.
Great River Road (Alton to Grafton)
Bluff-line highway along the Mississippi — eagles in winter, and the drive itself is the destination.
Best season · Illinois
April-June and September-October. Summer is humid downstate; winter is the eagle and ice-fall season along the rivers.
The legal picture
Illinois camping rules
Shawnee National Forest allows dispersed camping outside developed recreation areas — the only meaningful boondocking in Illinois.
Illinois state parks are designated-site only, and most require advance reservation through the IDNR system.
Chicago and the collar counties ban overnight vehicle parking almost universally; there is no legal urban van overnight in the metro.
Illinois interstate rest areas permit rest stops but not overnight camping, and posted limits are enforced.
Shawnee's forest roads are clay and gravel; a two-wheel-drive van should stick to the maintained routes after rain.

What the land agencies don't tell you about Illinois
Context the official pages skip — from time on these roads, not from a brochure.
Garden of the Gods gets Illinois's whole outdoor population on an October Saturday; the same trail at 7 a.m. midweek is empty and the light is better anyway.
Starved Rock's canyon waterfalls run hardest during spring thaw and after heavy rain, and the ice falls in January are the reason locals go in winter.
The Ohio River Scenic Byway across the bottom of the state is a genuinely quiet van road with river towns and no traffic, and almost no one from Chicago has driven it.
Winter eagle counts along the Mississippi near Alton and the Quad Cities are among the highest in the lower 48 — January is a real Illinois season, not a consolation.
Southern Illinois sits in a different climate zone from Chicago: Carbondale can be 15 degrees warmer in March, which stretches the shoulder season considerably.

Straight answers
Illinois van rental FAQ
Where can I boondock in Illinois?
Shawnee National Forest in the far south. Everywhere else in the state is designated-site camping, and the Chicago metro bans overnight vehicle parking outright.
Is Starved Rock worth a weekend?
Yes, but book the campground early and hike at dawn. It is the most-visited state park in Illinois and the canyon trails are single-file by mid-morning.
