Route: Tunnel Hill State Trail (IL)

Illinois, US

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.

Tunnel Hill State Trail stretches for 45 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.

Hi Shannon! I am sorry I missed this. How did it go? are you going to try it again? It is a lovely trail. Water can be scarce when the faucets are turned off.  I hope you are having fun adventures. Take care.
