You can pick up this trail either from Germantown Ave or from the end of the Wissahickon White Trail
North Segment. It is fairly flowy, but does include some rooty sections. If you decide to include this trail as part of a full loop around the park, you'll want to turn left on Germantown and take the access trail leading back to Forbidden Drive
. From Forbidden Drive
, you can access the singletrack on the Southwest side of the Wissahickon Creek.
