At one time, the rumble of freight cars reverberated through the narrow tunnel. Wooden trestles, with their system of slanted supports and horizontal cross pieces, spanned numerous bluffs and creeks. Passengers in Pullman cars clocked the miles with these and other landmarks as they traveled one of southern Illinois' most scenic routes.

Today, the railroad is gone. The route, known as Tunnel Hill State Trail, remains.
Tunnel Hill State Trail stretches for over 50 miles from Harrisburg to Karnak. The trail continues on a trails spur for 2.5 miles from Karnak to Cache River State Natural Area - Henry Barkhausen Wetlands Center on the old Chicago and Eastern Illinois railroad bed.

The trail (ranging in width from 40 to 200 feet) features ever-changing vistas, from lush wetlands including an ancient Cypress-tupelo swamp, abundant wildlife, picturesque trestles ranging from 34 to 450 feet, and incredible rock formations. 

Elevation ranges from 340 feet at Karnak on the southern end, to the highest point at Tunnel Hill at 680 feet, giving the trail a gentle 2% grade.
