Come out and get some exercise and enjoy the beauty of The Wissahickon. If you have never been, it's an urban oasis in the Chestnut HIll/Mt. Airy section of PHiladelphia that provide rolling trails that are sometimes easy, sometimes quite challenging. I anticipate perhaps a two hour, 4-5 mile hike. Please bring water! Dogs and FRiends WElcome! I like to go out early because this place fills up pretty quickly! There is a line of parking spots on NOrthwestern AVe. Chestnut HIll College is a landmark.
