For the 16 mile roundtrip, Lehigh Gorge Scenic Railway rides the former mainline of the Jersey Central Lines leaving historic downtown Jim Thorpe. The line swings over the old Nesquehoning Trestle onto the former Lehigh Valley main line before passing Glen Onoko. From here the Jersey Central track is long abandoned, but the Lehigh Gorge State Park trail has replaced it. Glen Onoko is at the southern gateway to the LGSP. The ride follows the winding Lehigh River for about 8 miles, rounding curve after curve until we reach Old Penn Haven Junction.
