The Lebanon Valley Rail Trail is a National Recreation Trail that travels through southwestern Lebanon County. Built on the corridor of the old Cornwall-Lebanon Rail Line, this former railroad provided recreational and military-industrial transportation services during its history. The trail passes by historic areas like the Borough of Mount Gretna and the Cornwall Furnace National Historic Site.

The Highlands Trail follows the Lebanon Valley Rail Trail from its connection with the Horse-Shoe Trail near Mount Gretna in West Cornwall Township and heads southwest for 3.6 miles. It connects to the Conewago Rail Trail just north of Elizabethtown.

The Lebanon Valley Rail Trail is a crushed-stone shared-use trail that also accommodates equestrians. All trail users must yield to horses. Dogs must be on a leash.

Average Slope: 1.0%; Maximum Slope: 27.7%
