The C&O Canal follows the route of the Potomac River for 184.5 miles from Washington, D.C. to Cumberland, MD. The canal operated from 1828-1924 as a transportation route, primarily hauling coal from western Maryland to the port of Georgetown in Washington, D.C. Hundreds of original structures, including locks, lockhouses, and aqueducts, serve as reminders of the canal's role as a transportation system during the Canal Era. In addition, the canal's towpath provides a nearly level, continuous trail through the spectacular scenery of the Potomac River Valley. Every year millions of visitors come to hike or bike the C&O Canal in order to enjoy the natural, cultural, and recreational opportunities available.

Harpers Ferry National Historical Park is located at the confluence of the Potomac and Shenandoah rivers in the states of West Virginia, Virginia, and Maryland. George Washington, Thomas Jefferson, Meriwether Lewis, John Brown, "Stonewall" Jackson, and Frederick Douglass are just a few of the prominent individuals who left their mark on this place. The story of Harpers Ferry is more than one event, one date, or one individual. It involves a diverse number of people and events that influenced the course of our nation's history. Harpers Ferry witnessed the first successful application of interchangeable manufacture, the arrival of the first successful American railroad, John Brown's attack on slavery, the largest surrender of Federal troops during the Civil War, and the education of former slaves in one of the earliest integrated schools in the United States.
