The Lehigh Valley Trail is the former home to one of the most celebrated American railroads of all time: The Lehigh Valley — home of the famous Black Diamond Express passenger train, which ran from New York to Buffalo.
While the land that comprises the Lehigh Valley Trail is owned by Monroe County Parks, this rails-to-trails project was created by (and is maintained, year-round by) a small but passionate non-profit group called the Mendon Foundation, and we at the Mendon Foundation depend on privately-collected donations and volunteer help to mow, groom and improve it so that you can continue to enjoy it, year-round, for walking, hiking, biking, running, and more.
If you’re a runner, one of the best ways you can support the Trail and the Mendon Foundation is to run the Black Diamond Express Races, on Sunday, August 29, 2021.
