Best Hikes in Southern Illinois

1. Garden of the Gods Observation Trail

Garden of the Gods Observation Trail is considered one of the best short hikes and most photographed locations in Southern Illinois. Sure, the observation trail in Harod isn’t going to help you log many miles, but it will reward you with panoramic views within the Shawnee National Forest.

There is no shortage of signs explaining the geological history, and numerous benches line the path if you are looking for the perfect spot for a picnic. You won’t be disappointed with all the unique sandstone rock formations.

There are additional Southern Illinois hiking trails nearby if you want to make a day of it at the Garden of the Gods Wilderness.

2. Heron Pond Trail

Heron Pond Trail in Cache River State Natural Area offers a unique ecosystem that most hikers wouldn’t even know existed in Southern Illinois.

You would almost believe you are in a Louisiana bayou or the Florida Everglades. The tree-lined path within Shawnee Forest eventually leads you to a floating boardwalk that gets you up close to the Cache River wetlands.

Hiking an extra .25 mile will bring you to a massive Cherrybark Oak Tree with a trunk over 22 feet in diameter.

3. Salt Lick Trail

The Salt Lick Trail is located on an old quarry site in Valmeyer, Illinois within the Salt Lick Point Land and Water Reserve. The initial climb up a bluff will get your legs burning, but beautiful views of Southern Illinois farm fields and even the St. Louis skyline will make it all better.

If you plan to combine trails to make a longer loop, we recommend using the Newman Trail to connect to the Johnson Trail.

4. Red Cedar Trail

Red Cedar Trail is one of the more rugged Giant City hiking trails with plenty of elevation gain. Red Cedar Trail is best suited for the avid hiker looking for a challenge and who wants to be rewarded with all things the Midwest has to offer.

The natural rock bridge spans 90 feet long, resulting from millions of years of erosion. Be sure to explore the small canyons and shallow caves nearby. Keep in mind that the bridge can be slippery after it rains, so wear proper hiking shoes for the best traction.

Deer Trail is a 3 mile loop nestled in Olin Nature Preserve just outside Alton, Illinois. You can expect many ups and downs as you travel on the well-marked path. The Deer Loop is the longest and most difficult trail in the nature preserve.

While you are hiking, you’ll see varying ecosystems, from prairie land to forests and you’ll even catch a glimpse of the Mississippi River. Don’t forget to take a quick detour on Beaver Trail to check out Beaver Falls.

A few things to take note of – no dogs are allowed in John M. Olin Nature Preserve and hiking trails can be closed during the winter months.

7. Pere Marquette Outer Loop

The Outer Loop Trail combines numerous hiking trails throughout Illinois’ largest state park – Pere Marquette. With nearly 8,000 acres of land and natural beauty, Pere Marquette State Park will give you a glimpse of the awesome scenery you will see in Southern Illinois.

River views, huge bluffs, dense forests, and an abundance of wildlife are only a few natural wonders you can look forward to. Elevation gains will be your best friend on this moderate hike (or maybe not), and if you plan your trip in the fall, colorful trees will be in abundance!
