Over the years, abandoned railways have been transformed into multi-use pathways around the country. One such trail is the Tunnel Hill State Trail, a 55-mile stretch between the towns of Harrisburg and Karnak. Along this pathway, you have the opportunity to hike through an abandoned train tunnel in Illinois. It’s a one-of-a-kind hike you won’t want to miss!

The Tunnel Hill State Trail is a multi-use, point-to-point trail that winds its way through some of Southern Illinois’ smallest towns and even a few ghost towns.

Once upon a time, this trail was a railway that was part of the Cairo and Vincennes Railroad. Construction of the rails was completed in 1874 and it was used for train cars to haul a variety of goods, including coal.

By 1991, after several ownership changes, the railway was turned over to the state of Illinois. By 1998, the first sections of the new multi-use Tunnel Hill State Trail was complete. The remainder of the trail was finished by 2001.

Along the trail, visitors can hike, run, or bike. It is mostly paved with gravel in some areas.

Depending on how far you travel along this trail, you’ll cross trestles and pass through a long, abandoned railroad tunnel.

The tunnel is over 500 feet and pitch dark inside. You may want to carry a flashlight with you or use the flashlight app on your cell phone.
