The Great Allegheny Passage (GAP), also known as the Cumberland & Pittsburgh Trail, is a rail trail in Maryland and Pennsylvania. It is the central trail of a network of long-distance hiker-biker trails covering hundreds of miles through the Allegheny region of the Appalachian Mountains, connecting Washington, D.C. to Pittsburgh, Pennsylvania and beyond.
The multi-use trail, suitable for biking and walking, occupies abandoned corridors of the Baltimore and Ohio Railroad, Pittsburgh and Lake Erie Railroad, Union Railroad and the Western Maryland Railway. The Great Allegheny Passage extends 150 miles (240 km) from Cumberland, Maryland to Point State Park in downtown Pittsburgh, Pennsylvania, with a 52-mile (84 km) branch (Montour Trail) to the Pittsburgh International Airport.
This GAP also connects with the Chesapeake and Ohio Canal towpath trail, which runs for an additional 185 miles (298 km) between Cumberland, Maryland and Washington, DC - creating a continuous non-motorized corridor, from Pittsburgh's Point State Park 339 miles (546 km)) to Washington, DC. The Great Allegheny Passage is a segment of the Potomac Heritage National Scenic Trail, one of eight nationally-designated scenic trails.
The route is popular for "through-travelers" including hikers, backpackers and cyclists traversing portions of the route from destination to destination, or the entire trail from end to end.
The Great Allegheny Passage is the key connecting segment of the Potomac Heritage National Scenic Trail, creating an off-road sight-seeing and backpacking corridor hundreds of miles long. Notable landmarks along the trail include:
- Fallingwater, a national architectural landmark designed by Frank Lloyd Wright.
- Carrie Furnace, part of the Steel Valley Heritage Trail, along the Monongahela River.
- Kennywood amusement park near Duquesne, Pennsylvania, this section of the trail was restricted during September 2013 due to a landslide.
- Dead Man's Hollow, former site of the Union Sewer Pipe Company located outside of McKeesport, Pennsylvania, best known for a history darkened by tragic events. Now a 440 acre nature preserve and spur trail.
- Historic Dravo Cemetery, originally the Seneca Tribe's village known as Cyrie, later the home of the Dravo Methodist Church and Cemetery. Now a popular camping area / rest spot near Buena Vista, Pennsylvania.

- Big Savage Tunnel, 3,295 feet (0.6 mi; 1.0 km), lighted, carries the trail through Big Savage Mountain two miles east of the Eastern Continental Divide; there's a popular scenic vista just east of the tunnel.
- Mason-Dixon Line: the border where the trail crosses between Pennsylvania and Maryland
- Borden Tunnel: 957 feet (292 m) long, unlighted.

- Brush Tunnel: 914 feet (279 m) long, lighted; the trail and the Western Maryland Scenic Railroad share this tunnel and pass through it side-by-side.
- Cumberland Bone Cave: (two or three miles west of Cumberland, Maryland: an archeological site containing bones of saber-toothed cats and other extinct animals; it was discovered during construction of the railroad.
- Canal Place, the head of the Chesapeake and Ohio Canal in Cumberland, Maryland where it meets the former Western Maryland Railway (WM) and rail-trail. In the 19th century WM's predecessor railroads delivered coal, flour and other products to a wharf for transfer to canal boats destined for Williamsport, Maryland and Georgetown, Washington, D.C.
Additional landmarks along the C&O Canal portion, which continues past the GAP Trail into D.C. include:
- Paw Paw Tunnel, a 3,118 feet (0.6 mi; 1.0 km) long canal tunnel, unlighted.
- Antietam National Battlefield, located 2 miles (3.2 km) from Dam 4.

- Great Falls of the Potomac River, the largest falls of any river on the eastern seaboard, and a destination for professional kayaking and rock-climbing.
- Mather Gorge and the Potomac palisades, a unique natural habitat of granite cliffs and boulders featuring the National Park Service's Billy Goat Trail.
- Georgetown, Washington, D.C., a historic town and neighborhood at the canal trailhead.
- The Potomac Heritage Trail continues south on a further bike trail past the Lincoln Memorial to Mount Vernon.
The Allegheny Trail Alliance is an affiliation of seven trail organizations involved with the Great Allegheny Passage: Friends of the Riverfront, Steel Valley Trail, Regional Trail Corporation, Ohiopyle State Park, and Mountains Maryland. Together they maintain the 150–mile Great Allegheny Passage.
At Cumberland the GAP system connects with the Chesapeake and Ohio Canal Towpath which is 184.5 miles long. The Great Allegheny Passage and the C&O Canal Towpath create a non-motorized nearly 335-mile trail between Washington, D.C. and Pittsburgh, PA.
The 9-mile (14 km) section between Woodcock Hollow and Cumberland opened on December 13, 2006. 150 miles (240 km) of continuous trail are now open from Pittsburgh, Pennsylvania to Cumberland, Maryland. Currently, the trail is a lane on road from Second Avenue in Pittsburgh to Point State Park. Plans to take that section off road are underway. The Point Made Celebrations took place on June 15, 2013 celebrating the connection to the forks of the Ohio.
