Frequently asked questions

How long is the Great Allegheny Passage and where does the full route go?

The Great Allegheny Passage is about 538.22 km, or roughly 334 miles, end to end. The GAP itself runs between Cumberland, Maryland, and Downtown Pittsburgh, Pennsylvania, and it is commonly paired with the C&O Canal Towpath to create the full Pittsburgh-to-Washington, D.C. journey.

How many days does it take to complete the Great Allegheny Passage?

A full end-to-end trip on the Great Allegheny Passage usually takes several days because the route covers about 538 km. Strong hikers or bikepackers often break it into roughly 5 to 10 days depending on daily mileage, overnight stops, and whether the trip includes the connected C&O Canal Towpath section toward Washington, D.C.

Is the Great Allegheny Passage difficult for beginners?

The Great Allegheny Passage is generally considered easy, with a long but gradual profile and about 1,164 m of total elevation gain spread across the route. Much of the trail follows former rail corridors, which keeps grades relatively gentle compared with mountain hiking trails.

What is the trail surface like on the Great Allegheny Passage?

Nearly all of the Great Allegheny Passage has an evenly topped crushed-limestone surface, with short paved sections in places such as Connellsville and Cumberland and a longer paved stretch between McKeesport and Downtown Pittsburgh. That rail-trail surface is one reason the route feels approachable despite its length.

Where can you park for the Great Allegheny Passage?

Parking is available in trail towns and at multiple trailheads along the Great Allegheny Passage, including Cumberland, Frostburg, Meyersdale, Rockwood, Ohiopyle, Connellsville, West Newton, Homestead, Pittsburgh’s South Side, and Downtown Pittsburgh. Overnight parking is more limited, and parking in Georgetown, Downtown Pittsburgh, and Pittsburgh’s South Side may require payment.

Are dogs allowed on the Great Allegheny Passage?

Dogs are allowed on the Great Allegheny Passage, but they should be kept on a leash at all times. On a long shared-use trail like this one, leash control matters especially on busier sections near Pittsburgh, Cumberland, Ohiopyle, and the Washington, D.C. end of the broader trail corridor.

What are the main landmarks on the Great Allegheny Passage?

One of the best-known landmarks on the Great Allegheny Passage is the Eastern Continental Divide, the highest point on the route at 2,392 feet above sea level. It sits between Meyersdale and Frostburg near McKenzie Hollow Road and marks the divide between the Chesapeake Bay and Mississippi River watersheds.
