Tunnel Hill State Trail

Tunnel Hill State Trail is a 45-mile rail route through Southern Illinois that passes through forests, wetlands, and farmland across multiple counties. The path follows the route of a former railroad and includes a notable tunnel along the way.

The route follows the former Cairo and Vincennes Railroad established in 1874, which moved coal and farm products through the region. This line played an important role in the economic development of Southern Illinois during that era.

Small towns along the route have preserved local museums and historic depots that reflect the railroad heritage of the area. Visitors can feel the connection to this past in these communities and learn about the people who once depended on the trains.

A tunnel section requires flashlights or bike lamps due to darkness inside. Multiple access points along the route have parking areas and restroom facilities for visitor convenience.

The trail passes through an area with ancient swamp cypress trees over 1000 years old. These rare trees are among the oldest living organisms in the entire region.
