The Ironton Rail Trail is in Lehigh County, north of Allentown.

The trail takes a paved six mile loop around Coplay and Hokendauqua and has a cinder covered spur off the western end of that loop that goes down to Portland and Quarry Streets near Ranger Lake. There are a number of historical sites along the way, most notably the Coplay Cement Kilns and the Troxell-Steckel House, as well as the remains of a number of railroad related items and an old cement mill.
