All around the nation, abandoned train tracks have been transformed and repurposed into outdoor recreational spaces for walking, hiking, and biking. The Tunnel Hill Trail in Southern Illinois is one such trail that follows the route of a railway that was abandoned long ago. This accessible trail is rated as easy and will take you through some gorgeous scenery along the way.
An abandoned train line between Harrisburg and Karnak was transformed into the Tunnel Hill Trail. In the 19th century, a track was constructed for the Cairo & Vincennes Railroad for freight trains to transport goods like coal and timber between Illinois and Indiana.
Over the years, the tracks changed ownership several times until they were abandoned for good.
In 1998, parts of the Tunnel Hill Trail opened and today it is 47.5 miles from end to end. This easy, lightly trafficked trail is part gravel and partially paved.
At four to eight feet wide along the entire length, it is both wheelchair and stroller friendly except for the steepest section at the 24.6-mile mark when heading south. This is where you'll find a steep 12% incline and may need some help.
Throughout the long trail, you'll traverse through several small towns and ghost towns of Southern Illinois. You'll also cross over at least two dozen trestles found over water and ravines, through parts of the Shawnee National Forest, past bluffs, alongside a river, and through a long railroad tunnel.
The former train tunnel is over 500 feet long with no lighting, so bring a flashlight - or if you're biking, make sure you have bike lights. Otherwise, it's almost pitch dark!
Aside from the fascinating train tunnel, there's plenty of nature viewing and bird watching along the trail.
You'll find so much scenic beauty along the way as you picture what it was like in the days when the trains ran along the tracks. It's a truly fascinating place to hike, walk, or bike in the state of Illinois.
