The Wissahickon Trail passes along or through private property and sensitive floodplain properties. Access for parking points along the trail will be limited to the existing Fairmount Park trailhead in Chestnut Hill at Northwestern Avenue and at the Militia Hill section of the Fort Washington State Park in Whitemarsh Township. Limited parking is planned for the W. Valley Green Road/Stenton Avenue area and along West Valley Green Road at the Philadelphia Cricket Club.
In addition to the major trailhead access points, visitors who ride bicycles to the trail can access the trail at various street crossing areas, including Northwestern Avenue, Stenton Avenue, West Valley Green Road, and Bethlehem Pike at Morris Road. Springfield Township is also planning a system of trails that will link Flourtown and Erdenheim villages to the trail. Visitors who use the Schuylkill River Trail and the Cross County Trail will have seamless access to the trail.
