Why Visit Great Allegheny Passage (GAP Trail)

The allure of the Great Allegheny Passage (GAP Trail) lies in its unique blend of history, nature, and accessibility. This meticulously maintained rail-trail, largely built on abandoned railway corridors, provides a smooth, crushed-limestone surface that’s ideal for biking and hiking. We find that the gentle grades, a legacy of its railroad origins, make it enjoyable for all skill levels.

Beyond the natural beauty, the GAP Trail is a living museum. You'll encounter numerous historical sites, including remnants of the French and Indian Wars, and the pioneering era of Western exploration. The trail also boasts impressive engineering marvels, such as the Salisbury Viaduct and the iconic Big Savage Tunnel, which at 3,300 feet long, offers a cool, dark passage through the mountain. The ability to connect with the 184.5-mile C&O Canal Towpath in Cumberland, Maryland, extends the adventure to a continuous 335-mile car-free route all the way to Washington, D.C., creating one of the longest multi-purpose trails in the country.
