About This Trail

The Green Ribbon and Wissahickon Trail follows Wissahickon Creek for about twelve miles through Montgomery County, from Parkside Place Park in Upper Gwynedd Township downstream to Stenton Avenue at the Philadelphia line. It is a creekside greenway, not a rail corridor. The upper ten miles are the Green Ribbon Trail, a narrow foot path on hard-packed dirt with stretches of gravel, mowed grass, and wooden footbridges; bikes are not permitted there. Below Skippack Pike the route becomes the Wissahickon Trail through Fort Washington State Park, a wider multi-use path that carries bikes toward Forbidden Drive. The whole way is nearly flat and stays close to the water, passing the Evans-Mumbower Mill, Penllyn Woods, and the Four Mills Nature Reserve.

RailTrailWx TIPS

Green Ribbon & Wissahickon Trail

Your comfort. Prognosticated.

  • The trail is well shaded for nearly its whole length, with about half of it under deep canopy along the creek, so it stays cool on summer afternoons and dries slowly after rain.
  • The route hugs the creek on a flat floodplain the entire way. The watershed association was founded over flooding, and the creekside path and its footbridges go under water after heavy rain; check the Wissahickon Trails page before a trip if the creek has been high.
  • Wooden footbridges and boardwalks on the Green Ribbon section are very slippery when wet or frosted, and there are many of them.
  • Bikes are allowed only on the lower end, the widened Wissahickon Trail in Fort Washington State Park below Skippack Pike. The Green Ribbon Trail above it is foot traffic only. Fort Washington State Park also welcomes cross-country skiers on the trail in snow.
  • In fall the Militia Hill hawk watch in Fort Washington State Park counts migrating raptors; a clear day with a north or northwest wind brings the biggest flights over the ridge beside the trail.
  • Wissahickon Trails posts temporary closures for repairs, such as the 2026 re-alignment near Gwynedd Valley station between miles 6.75 and 7; look for notices at trailheads and on its website.

Trivia

  • The creek's name comes from the Lenape word wiessahitkonk, meaning catfish creek or stream of yellowish color.
  • Wissahickon Creek runs about 23 miles from its Montgomery County headwaters to the Schuylkill River in Philadelphia.
  • The site of the Evans-Mumbower Mill was part of a land grant to Thomas Evans in 1698, and his grandson Abraham built a saw mill there in 1744.
  • John and Elisa Keefe built the present mill in 1835 and set a name stone in its front wall; it ground grain until 1930 and joined the National Register of Historic Places in 2008.
  • Wissahickon Trails began on April 20, 1955, when nine neighbors met to address flooding in the Wissahickon Valley.
  • The Four Mills Barn in Ambler was designed by Philadelphia architect Horace Trumbauer and built in 1891 as part of an estate called Abendruh.
  • About 12,000 soldiers of Washington's army camped in the Whitemarsh hills from November 2 to December 11, 1777, and Pennsylvania militia held the rise now called Militia Hill.
  • Volunteers have counted migrating raptors from Militia Hill in Fort Washington State Park every fall since 1988.

History

Wissahickon Creek turned mill wheels for two centuries before anyone thought of it as a trail. Thomas Evans took up a land grant on the creek in 1698, and his grandson Abraham built a saw mill there in 1744. John and Elisa Keefe rebuilt it in stone in 1835. Henry Mumbower bought the mill in 1856, his son David ran it after him, and the wheel stopped in 1930. Farther down, the Whitemarsh hills above the creek held Washington's army for six weeks in late 1777, and Pennsylvania militia camped on the rise now called Militia Hill. No railroad ever ran this valley floor; the corridor is the creek itself. On April 20, 1955, nine residents met to address flooding along the Wissahickon. In 1957 they formed the Wissahickon Valley Watershed Association, the group now called Wissahickon Trails. Over the next fifty years the association assembled creekside land piece by piece until the Green Ribbon Trail ran the length of the valley through six townships and two boroughs. It took ownership of the collapsing Evans-Mumbower Mill in 1987 and restored it. Montgomery County took up the lower end as the Wissahickon Trail, widening two miles inside Fort Washington State Park to twelve feet and paving a half mile along Northwestern Avenue in 2008. In 2022 the Pennsylvania Chapter of the American Planning Association named the Green Ribbon Trail and Preserve a Great Place in Pennsylvania.
