Valley Line Trail (Skokie Valley Trail)
Time Out says
If you're looking for a direct route to Skokie from the Far North Side, you can't beat the Valley Line Trail (a.k.a. the Skokie Valley Trail), a paved path that runs through Sauganash and Lincoln Wood on its way to the Northern suburb. If you're coming from Chicago, you can hop on the trail just to the east of Bryn Mawr and Kostner avenues, continuing north past greenspaces like Sauganash Park and the Emily Oaks Nature Center. The trail appears to end just past the Skokie-Dempster Yellow Line station, but there's an extention farther north at Golf Road and Laramie Avenue, taking you under I-94 to Old Orchard Road.
