The Cobbs Creek Trail, a 3.7 mile asphalt path, is a lovely, tree-lined corridor on the banks of Cobbs Creek. It stretches from Church Lane in Yeadon north to Market Street in Upper Darby (in Delaware County). One highlight of the trail is the section through historic Mount Moriah Cemetery. There are plans to extend the path as far as the Heinz Wildlife Refuge. Run the trail 7.4 miles out and back, or go one way and return on the trolley!
