Here in the Land of Lincoln, we are proud to have so much natural beauty and our state stands out in the Midwest as one with unmatched hiking trails, historic sites, and other beautiful places which we savor. We want to share the very best of them so that you can enjoy them too when you come to visit! Let’s take a look at 15 incredible natural wonders in Illinois.

Best Gorges & Canyons In Illinois

We may be called The Prairie State, but we have a lot more than just prairies to boast about. Our gorges and canyons in Illinois will hold up against those in any other state for their sheer beauty. Here are three of the best.

1. Slot Canyon in the Shawnee National Forest

Location: Sparks Hill, Illinois

Wow Factor: It's like an Illinois version of Arizona's Antelope Canyon.

Cost Free.

There’s a slot canyon hidden within the Pounds Hollow Recreational Area in the Shawnee National Forest that will take your breath away. The hike to this area is gorgeous in its own right with sweeping overlooks and stunning vistas which lead to a set of wooden stairs. Suddenly you’re descending into a narrow slot canyon as wide as your shoulders. You’ll be surrounded by ancient sandstone rock formations that eventually lead out to Ox-Lot Cave. It’s a short 1.5-mile hike that’s a true hidden gem in Illinois.

2. Little Grand Canyon

Location: Pomona, Illinois

Wow Factor: All of the beauty and majesty of the Grand Canyon, but smaller.

Cost Free.

Tucked away in the Shawnee National Forest in Southern Illinois is this astounding canyon that bears no small resemblance to the Grand Canyon. Little Grand Canyon is made up of sandstone walls with lush green ferns strewn about. This canyon, like its namesake, was carved by water over millions of years. While it’s a treat to look down from the top, hike to the bottom, look up at these canyon walls, and be awed by the beauty of this place. In the spring, wildflowers bloom throughout, and in the fall the foliage comes alive with color.

3. LaSalle Canyon

Location: Starved Rock State Park, Deer Park Township, Illinois

Wow Factor: Starved Rock State Park has 18 sandstone Canyons. This is the best of them!

Cost Free.

The moderate 2.3-mile out-and-back trail that leads here takes you through forests, a cave, a waterfall, and scenic river views. All of that plus an awe-inspiring canyon? What a truly fantastic place to visit! LaSalle Canyon is nestled within Starved Rock State Park which has 17 other sandstone canyons, but this one stands out with its verdant foliage and intriguing sandstone bluffs. Seeing the Illinois River and the multiple waterfalls in this canyon makes for one of the best day trips in the state for getting out of the city and into some of the best nature in Illinois.

Best Caves In Illinois

You’ll find such a wide variety of caves in Illinois, from little nooks tucked away in the rocks to vast sprawling underground caverns that wander deep into the earth. There’s something about these mysterious underground places that evoke our natural curiosity and draw us further in to see what we’ll find next. Some have quite a history attached to them and others are admired for their otherworldly beauty.

4. Illinois Caverns State Natural Area

Location: Waterloo, Illinois

Wow Factor: Spelunkers have been taking note of this expansive cave system since 1901!

Cost Free, but a permit must be filled out.

This cave system has had several attempts to gain tourism since 1901 and has had many names as well, including Egyptian Cave, Burksville Cave, Mammoth Cave, and Eckert Cave. Now it is known as Illinois Caverns. If you’re looking to try your hand at spelunking, this is the perfect place for it. You’ll need some safety gear like a helmet, several flashlights, and some good hiking boots, but you won’t get lost as the single pathway is clearly marked. You’ll need to fill out a permit, but groups of four or more people can enter for free. Come explore the best cave in Illinois.

5. Sand Cave

Location: Waterloo, Illinois

Wow Factor: This cave has a storied history as a stop along the Underground Railroad.

Cost Free.

Sand Cave is a little-known cave in the Ozarks that was used as a hiding spot along the Underground Railroad in the 1800s. It won’t be crowded and it’s quite the experience to sit within this cave and reflect on what it must have been like for those who hid here while seeking a way to freedom. You can get to it on a fairly easy 1.2-mile trail which is great for hikers, horseback riders, and birders. This historical cave is also a place of serene beauty worthy of a wonderful day trip.

Best Waterfalls In Illinois

We’ve shown you verdant canyons and intriguing caverns, now it’s time for cascading waterfalls in Illinois. The forest preserves, national parks, and miles of trails throughout Illinois all contain some of these majestic flowing falls. They’re perfect places for soothing your daily stress and taking in the wonder of nature.

6. Ferne Clyffe Falls

Location: Ferne Clyffe State Park, Goreville, Illinois

Wow Factor: Lush, rushing waterfalls that you can walk behind!

Cost Free.

If you want to see some wonderful waterfalls but don’t want to take a long hike to get to them, then you’ll love Ferne Clyffe Falls. The round trip on the Big Rocky Hollow Trail is less than a mile. The falls are broken up into two sections. The first is a 50-foot waterfall dropping from a cliff. The second is about 20 feet of rock formations with the falls washing over them and dropping into a pool below. What a great way to spend a relaxing day!

7. Cascade Falls

Location: Matthiessen State Park, Oglesby, Illinois

Wow Factor: A lesser-known waterfall that is one of the most gorgeous waterfalls in the entire Midwest.

Cost Free.

This truly stunning 45-foot-high waterfall is sadly under-appreciated and doesn’t get as many visitors as places like Starved Rock, but it is well worth visiting on its own. The little ecosystem here is especially impressive in the spring when the snowmelt surges forth into the beautiful canyon. During the fall, the water is still lovely and is surrounded by vibrant autumn foliage. Cascade Falls should be on your Illinois waterfall bucket list for sure!

Best Rock Formations in Illinois

All of the natural places we’ve covered so far would be lacking if they didn’t contain a framework of rock formations in Illinois which appear in endless shapes and sizes and can also make for some fun rock climbing among the hickory and cypress trees on the hills and in the ravines of this lovely state. Here are two of the best rock formations in the Prairie State.

11. Garden of the Gods

Location: Herod, Illinois

Wow Factor: This is 3,300 acres of the most renowned rock formations in Illinois.

Cost $10 for camping.

We can’t talk about rock formations in Illinois without putting the Garden of the Gods first. These were formed by 300 million years of winds into myriad shapes inspiring names like Mushroom Rock, Camel Rock, and Anvil Rock. This was a sacred place to Native American nations who considered this neutral ground. No violence was to happen here. It is certainly a place of must-see nature in Illinois. For $10 per night, you can camp in this achingly beautiful place. Campsites have toilets, fire pits, and picnic tables.

12. Pomona Natural Bridge

Location: Pomona, Illinois

Wow Factor: A 90-foot natural stone bridge that was formed by erosion over millions of years.

Cost Free.

Second only to Garden of the Gods, the Pomona Natural Bridge is an iconic rock formation in Illinois.

14. White Pines Forest State Park

Location: Mt. Morris, Illinois

Wow Factor: A photographer’s dream with lush and mesmerizing riverside cliffs.

Cost $10/night for camping.

White Pines Forest State Park is lesser known and smaller than most state parks at 385 acres, however, it has a multitude of variations in its different kinds of scenery.

Such a remarkable history makes Cave-In-Rock an astounding place to visit. You can paddle there yourself when the river is low or take a ferry.
