Top 10 Illinois State Parks — In-Depth
1. Starved Rock State Park — Illinois’ #1 Park
Starved Rock draws 2+ million visitors annually to its 18 sandstone canyons carved by glacial meltwater along the Illinois River. In spring and winter, seasonal waterfalls cascade over moss-covered canyon walls. The park has a historic CCC-built lodge (1933), making it one of the few state parks with a full-service restaurant and overnight lodge.
- Must-do: French Canyon and St. Louis Canyon (waterfalls after rain/snowmelt)
- Unique: 18 named canyons in a 2,630-acre park — canyon density like nowhere else in the Midwest
- Lodge: CCC-built stone lodge with restaurant (book months ahead)
- Trails: 13 miles of well-marked canyon trails
2. Matthiessen State Park — Starved Rock’s Quieter Twin
Matthiessen sits just 2 miles from Starved Rock with its own dramatic canyons but a fraction of the crowds. The upper and lower canyon trails feature waterfalls, moss-covered walls, and geological features rivaling its famous neighbor.
3. Garden of the Gods — Shawnee’s Crown Jewel
Garden of the Gods in the Shawnee National Forest features 320-million-year-old sandstone formations with names like Camel Rock, Devil’s Smokestack, and Anvil Rock. The Observation Trail offers panoramic views across the Shawnee Hills — one of the most photographed spots in Illinois.
4. Giant City State Park
Giant City in southern Illinois features massive sandstone blocks arranged like city streets — the “Giant City” formations. A CCC-built lodge (1930s) serves acclaimed Southern cooking, and the park’s climbing routes attract boulderers from across the Midwest.
5. Pere Marquette State Park
Pere Marquette overlooks the confluence of the Illinois and Mississippi Rivers from dramatic limestone bluffs. The CCC-built lodge is a masterpiece with a 700-ton stone fireplace. Winter brings bald eagle viewing at the nearby Audubon Center.
6. Cahokia Mounds State Historic Site
Cahokia Mounds is a UNESCO World Heritage Site — the largest pre-Columbian settlement north of Mexico. Monks Mound, the largest earthen structure in the Americas, rises 100 feet above the Mississippi floodplain. The site preserves 70 of the original 120 mounds from a city that at its peak (1100 AD) was larger than London.
7. Mississippi Palisades State Park
Mississippi Palisades features dramatic limestone bluffs towering 250+ feet above the Mississippi River. Trails wind along cliff edges with spectacular river views, and the bluffs host unique plant communities.
8. Apple River Canyon State Park
Apple River Canyon in northwest Illinois is a hidden gem with limestone canyons, spring-fed streams, and some of the state’s best wildflower displays.
9. Ferne Clyffe State Park
Ferne Clyffe in the Shawnee Hills has a massive 150-foot semi-circular bluff shelter, seasonal waterfall, and excellent hiking through a fern-filled canyon.
10. Illinois Beach State Park
Illinois Beach is the state’s only remaining Lake Michigan beach park — 6.5 miles of sandy beach and dune habitat, plus the Illinois Beach Resort & Conference Center.
