Top Hiking Trails in Illinois
1. Garden of the Gods Observation Trail
Location: Shawnee National Forest, Southern Illinois
Difficulty: Easy to moderate
Distance: Approximately 0.25 mile loop
The Garden of the Gods Observation Trail is arguably one of the most recognizable hiking experiences in Illinois. Located within the Shawnee National Forest, this short trail takes visitors through a remarkable collection of ancient sandstone formations and elevated viewpoints.
Although the trail is short, the scenery makes it feel much more substantial. Massive rock formations rise from the forest, creating natural windows and dramatic viewpoints over the surrounding landscape.
The formations were created over hundreds of millions of years, and the area’s geological history is one of the major attractions. The observation trail is particularly popular with photographers and visitors looking for spectacular sunrise and sunset scenery.
Despite its relatively short distance, hikers should not assume that it is completely effortless. There are steps, uneven surfaces, and sections where caution is necessary.
For travelers searching for easy hiking trails in Illinois with amazing views, Garden of the Gods should be near the top of the list. The wider Garden of the Gods area also contains approximately 5.5 miles of interconnected trails for people who want a longer adventure.
2. Starved Rock and Sandstone Point Overlook Trail
Location: Starved Rock State Park
Difficulty: Moderate
Distance: Approximately 4.3 miles
Starved Rock State Park is one of the most famous outdoor destinations in Illinois, and for good reason. Its network of trails combines waterfalls, sandstone canyons, forests, river views, and dramatic overlooks.
The Starved Rock and Sandstone Point Overlook Trail is an excellent choice for hikers who want to experience several of the park’s features in one outing.
The trail provides views of the Illinois River and surrounding forest while taking hikers through the characteristic landscape that makes Starved Rock so popular.
Starved Rock State Park currently has approximately 13 miles of marked trails. Some routes are relatively short, while others involve more significant distances and stairways. The Illinois Department of Natural Resources also warns visitors to remain on designated trails and exercise caution around canyon areas and sandstone features.
For anyone creating a list of the best hiking trails near Chicago, Starved Rock deserves special consideration because it is roughly 90 minutes from the city under typical driving conditions.
3. St. Louis Canyon Trail
Location: Starved Rock State Park
Difficulty: Moderate
Distance: Approximately 3 miles round trip
If waterfalls are your main reason for hiking, the St. Louis Canyon Trail is one of the Illinois trails worth exploring.
The trail leads hikers into one of Starved Rock’s beautiful canyons, where the landscape becomes noticeably different from the surrounding forest. During periods of sufficient rainfall, water cascades down the canyon walls, producing one of the park’s most attractive natural features.
One important thing to remember is that many waterfalls in Starved Rock are seasonal or rain-dependent. The Illinois Department of Natural Resources specifically advises visitors to check weather conditions because canyon waterfalls can disappear when rainfall is limited.
This makes St. Louis Canyon especially attractive after periods of rain, although wet conditions can also make rocks and trails slippery.
4. Matthiessen State Park Dells Trails
Location: Oglesby/Utica area
Difficulty: Easy to challenging depending on route
Distance: Approximately 5 miles of hiking trails in the park
Located near Starved Rock, Matthiessen State Park is sometimes overshadowed by its more famous neighbor, but it offers an impressive hiking experience of its own.
The park features approximately five miles of well-marked hiking trails. Visitors can explore bluff tops, forests, streams, waterfalls, and the interior of its distinctive dells.
The upper areas generally offer easier hiking, while routes descending into the dells can become considerably more challenging, particularly during spring and early summer.
The combination of sandstone formations, vegetation, water, and canyon-like terrain makes Matthiessen a fantastic choice for hikers who want scenic variety without limiting themselves to one type of landscape.
The park authorities warn hikers to stay on marked trails because steep cliffs and deep canyons can present serious hazards.
5. Giant City Nature Trail
Location: Giant City State Park, near Makanda
Difficulty: Easy to moderate
Distance: Approximately 1 mile
The Giant City Nature Trail offers one of the most unusual hiking experiences in Illinois.
As its name suggests, the trail takes hikers through enormous sandstone formations that resemble the streets and structures of a giant stone city. These formations are one of the defining attractions of Giant City State Park.
The trail is relatively short, making it a great option for families, casual hikers, and visitors who want impressive scenery without committing to a full-day hike.
Along the route, hikers encounter towering sandstone bluffs, narrow passages, forest vegetation, and interesting geological formations.
Giant City State Park has multiple hiking options, ranging from short nature trails to the much longer Red Cedar Trail. The Illinois Department of Natural Resources identifies the Giant City Nature Trail as one of the park’s especially popular hiking experiences.
6. Red Cedar Hiking Trail
Location: Giant City State Park
Difficulty: Difficult
Distance: Approximately 12 miles
For experienced hikers searching for a longer challenge, the Red Cedar Hiking Trail at Giant City State Park is an excellent option.
At approximately 12 miles, this trail is substantially more demanding than the short nature trails in the park. It passes through rugged terrain and is designed for hikers seeking a more rustic experience.
The official park information describes the Red Cedar Trail as rugged and notes that leisurely hikers may need up to two days to complete it. There is also a camping location around the six-mile point, making it suitable for a backpacking adventure.
This is not the trail to choose if you are simply looking for a quick afternoon walk. Proper preparation, sufficient water, suitable footwear, food, navigation equipment, and awareness of weather conditions are important.
For experienced outdoor enthusiasts, however, Red Cedar provides a much deeper exploration of southern Illinois’ forests and sandstone terrain.
7. Ferne Clyffe State Park – Big Rocky Hollow Trail
Location: Southern Illinois
Difficulty: Easy to moderate
The Big Rocky Hollow Trail at Ferne Clyffe State Park is another excellent option for people searching for waterfalls and dramatic natural scenery.
The trail passes through a lush canyon-like environment filled with greenery, rock formations, moss, and ferns. Its major attraction is a waterfall that becomes particularly impressive when there has been enough rainfall.
Unlike some of Illinois’ longer hiking routes, Big Rocky Hollow is accessible to people who want a relatively manageable adventure.
It is particularly attractive during seasons when the surrounding vegetation is green and the waterfall is flowing.
For families and beginner hikers searching for waterfall hikes in Illinois, Ferne Clyffe provides an appealing combination of scenery and accessibility.
8. Little Grand Canyon Trail
Location: Shawnee National Forest
Difficulty: Moderate to difficult
Distance: Approximately 3 miles
The Little Grand Canyon Trail demonstrates just how dramatic southern Illinois’ landscape can become.
The approximately three-mile loop takes hikers through forested terrain and a canyon landscape featuring rock formations and seasonal waterfalls.
Unlike the extremely short Garden of the Gods Observation Trail, Little Grand Canyon offers a more immersive hiking experience. Hikers descend into the canyon before navigating the terrain and eventually completing the loop.
The scenery can be particularly impressive after rainfall, although wet weather can also make sections of the trail more difficult.
This trail is a good choice for people who want something more adventurous than a simple nature walk but do not necessarily want to commit to a 10- or 12-mile hike. Illinois tourism authorities specifically highlight Little Grand Canyon among the state’s notable southern Illinois hiking experiences.
9. Giant City Trillium Trail
Location: Giant City State Park
Difficulty: Rugged
Distance: Approximately 2 miles
The Trillium Trail provides another way to experience Giant City State Park beyond its famous Giant City Nature Trail.
At approximately two miles, it is short enough for a day visit but rugged enough to provide a stronger hiking experience.
The trail passes through forest and bluff environments and offers opportunities to observe seasonal plants and wildflowers.
One of the advantages of hiking at Giant City is that visitors can combine several trails according to their interests and available time. Someone looking for a relaxed outing can choose a short trail, while experienced hikers can combine routes or tackle the 12-mile Red Cedar Trail.
10. Cache River Wetlands – Lower Cache River Swamp Trail
Location: Southern Illinois
Difficulty: Easy
The Lower Cache River Swamp Trail provides a completely different hiking experience from the sandstone landscapes of southern Illinois.
Instead of cliffs and canyons, hikers encounter wetlands, cypress trees, water tupelo, and a distinctive flooded forest environment.
This trail is particularly appealing to birdwatchers, nature photographers, families, and people interested in wildlife.
The landscape demonstrates the ecological diversity of Illinois and proves that hiking in the state is not limited to hills and rocky terrain.
The Cache River area is also associated with paddling opportunities, allowing visitors to combine hiking with canoeing or kayaking for a more complete outdoor adventure.
How to Choose the Best Hiking Trail in Illinois
The best trail depends heavily on what you want from your outdoor adventure.
If you want dramatic views, Garden of the Gods is difficult to beat. Its sandstone formations and elevated viewpoints provide some of the most recognizable scenery in Illinois.
If you want waterfalls and canyons, Starved Rock, St. Louis Canyon, Matthiessen State Park, and Ferne Clyffe are excellent choices.
For families and beginners, short trails such as Garden of the Gods Observation Trail and Giant City Nature Trail are good starting points.
For experienced hikers, Red Cedar and longer routes around Starved Rock provide greater challenges.
And if you want wildlife and wetlands, Cache River offers something completely different.
Best Time to Go Hiking in Illinois
Illinois hiking can be enjoyed throughout the year, but each season offers a different experience.
Spring is excellent for waterfalls, wildflowers, and fresh greenery. However, trails can become muddy and slippery after heavy rainfall.
Summer brings lush vegetation and longer daylight hours, but temperatures and humidity can make longer hikes challenging. Carry plenty of water and start early when possible.
Fall is arguably one of the most beautiful seasons for hiking in Illinois. Forests become filled with autumn colors, making trails around Starved Rock, Giant City, and southern Illinois particularly attractive.
Winter offers a quieter experience, and some sandstone landscapes can become especially dramatic when covered in snow or ice. However, hikers should prepare for cold temperatures, slippery surfaces, and shorter daylight hours.
Always check current trail conditions and park notices before beginning your hike. Conditions can change, and some trails may temporarily close because of maintenance, weather, erosion, or other issues. Starved Rock, for example, is undergoing a major trail improvement project during 2026, with some trails experiencing closures or limited access.
Hiking Safety Tips for Illinois Trails
Before heading out, make sure you are properly prepared.
Wear shoes or boots with good traction, especially when hiking around sandstone formations, waterfalls, and canyon environments. Bring enough drinking water, snacks, sunscreen, insect protection, and weather-appropriate clothing.
Stay on designated trails. This is particularly important around cliffs and canyons where seemingly harmless shortcuts can become dangerous.
If you are hiking alone, tell someone where you are going and approximately when you expect to return. For longer trails, consider carrying a basic first-aid kit and a fully charged phone.
Also pay attention to weather forecasts. Rain can dramatically change trail conditions, while heavy rainfall may create waterfalls but also make rocks and canyon floors slippery.
At parks such as Giant City and Starved Rock, visitors are specifically instructed to remain on designated trails and exercise caution around cliffs, sandstone, and canyon areas.
