Named one of the “10 Best Places to Get Away this Fall” by National Geographic travel editors, the Great Allegheny Passage (GAP) is one of America's best hiking and biking trails. The final link to Pittsburgh will be completed this year, allowing travelers to explore the current 141-mile trail experience from Homestead, Pa., to Cumberland, Md., where the GAP joins the C&O Canal Towpath for a continuous trail experience - 325 miles long — to Washington, D.C.
