The Great Allegheny Passage, or GAP, was once a rail line. Now it's a 150-mile multi-use trail that winds through Maryland and Pennsylvania, with this section traveling alongside the Casselman River. The trail surface is mostly crushed stone dust with occasional stretches of pavement, so it's easily ridden on a touring bike.

From Pittsburgh to Cumberland it is a gradual uphill grade with a nice decent into Cumberland. Going west, the uphill grade climb out of Cumberland is one you will want to investigate to be sure you are up for that. The trail covers a lot of historical locations and you can see some nice videos about the GAP on YouTube search for @railtrailbikeadventures and see the playlist. Really nice and informative. Highly suggest riding this 150 mile trail - it is on the Rail Trail Hall of Fame list!

The best bike trip I’ve been on. You need water, regular clothes change (warm/cold weather), some money for nice restaurants on the way, and company
