The Great Allegheny Passage from Cumberland to Frostburg offers a unique hiking experience, following the historic Western Maryland Railway route through Maryland's mountains. You'll traverse the impressive Cumberland Narrows, a 900-foot-deep gorge, and pass through the lighted Brush Tunnel, which is shared with the scenic railroad. The trail is primarily packed, crushed limestone, offering a smooth surface as it winds through diverse, often wooded scenery.
This difficult 24.1-mile (38.9 km) hike involves a continuous 2227 feet (679 metres) of elevation gain, taking approximately 10 hours and 29 minutes. Parking is readily available at the Cumberland trailhead. For a less strenuous return, consider taking the Western Maryland Scenic Railroad from Frostburg back to Cumberland, which can also transport bikes. This makes it a great option for those who want the challenge of the uphill without the full out-and-back.
This section of the GAP trail is rich in history and natural features, including the Mason-Dixon Line Monument. You might even spot a vintage train from the Western Maryland Scenic Railroad running parallel to the trail. Frostburg itself is a charming college town with amenities, making it a rewarding destination after your long climb.
