Allegheny Highlands Trail of Maryland - Great Allegheny Passage

Trail Map

Description Suggest an Edit

The Allegheny Highlands Trail of Maryland (AHTM) follows the route of the old Western Maryland Railroad for 22 miles, between Cumberland, Maryland, and the Maryland–Pennsylvania border north of Frostburg. Part of the AHTM route parallels the Western Maryland Scenic Railroad and its tourist steam locomotive, which provides scenic three-hour excursions. The trail is flat relatively with a surface of crushed limestone (some paved sections) and offers beautiful scenery in the rolling hills of western Maryland.

If you begin in Frostburg at the Frostburg Depot, you can head in two directions: to Cumberland or to the state border. Built in 1891, the depot was both a passenger and freight station. In 1989 it was restored as a restaurant and is now the endpoint of the Western Maryland Scenic Railroad tour.

From Frostburg follow the AHTM north to the Mason-Dixon Line, about 5 miles. En route you will pass through the Borden Tunnel, built in 1911 and nearly 1,000 feet long. On a hot summer day it provides a refreshing release from the heat. The trail is part of the Great Allegheny Passage, which will take you all the way to Pittsburgh.

If you head southeast from Frostburg, the Allegheny Highlands Trail of Maryland goes to Cumberland, a scenic town with plenty of charm. Here you can continue to Washington, D.C., along the C&O Canal Towpath.

Parking and Trail Access

In Cumberland, park at the southern end point off Canal Street across from the Western Maryland Scenic Railroad depot. In Frostburg, park off Depot Street near where it meets New Hope Road or off New Hope Road just north of Rankin Drive.


Steady climb with a terrific payoff at the top

We rode on a hot, humid Memorial Day from Cumberland through Frostburg, on to the Big Savage tunnel and then the small crossroads of Deal, PA, 50 miles round-trip. The surface is in excellent shape with only a few very short stretches of loose gravel. more

On Sunday August 28, had a great day on the GAP. Started by riding Mountain Thunder of the Western Maryland Scenic Railroad from Cumberland to Frostburg (took our bikes with us). Then jumped on the bikes and did the 7 mile uphill to the Big Savage Tunnel. more
