The Saucon Rail Trail was part of the original Pennsylvania Railroad that ran from Philadelphia to Bethlehem. In 2011 a section between Hellertown and Coopersburg was developed as the Saucon Rail Trail, it is currently seven miles in distance one way.

In 2017 there are plans to connect the Saucon Rail Trail between Hellertown and the Bethlehem Greenway. As well there are plans in place to go further South, close to Quakertown.
