Upcoming Workdays

CANCELLED: Thursday, 11/15 - Trail Work Thursdays

This workday has been cancelled due to weather.

Saturday, 11/17 - Trails and Troegs for OktoberForest

Saturday, 11/17
9 – 1 pm
Meet at Upper Andorra Lot

Friends of the Wissahickon, Hidden City, The Nature Conservancy, Troegs Independent Brewery & the Young Friends of Preservation Alliance are teaming up to celebrate healthy forest, clean water and great beer in Wissahickon Valley Park. The Nature Conservancy’s OktoberForest is a campaign to raise awareness for the role healthy forests play in filtering water, beer’s main ingredient. What better place to celebrate then the 1800-acre Wissahickon Valley Park! The dense forests within the park protect one of the city’s most vital resources, the Wissahickon Creek, which provides drinking water for up to 350,000 Philadelphians.

We’ll be working on trail restoration, improving drainage, and stabilizing tread in the Andorra Meadow. Please join us for this fun day to help make this amazing section of the park cleaner, more sustainable, and even more beautiful. Meet at the upper Andorra parking lot on Northwestern Avenue, off of Ridge Avenue. Parking is limited here, so consider parking near Northwestern Stables on the Chestnut Hill side and then walking up the road passed the Tree House.

Following the work day, we will conclude with a Troegs Beer tasting at the Wissahickon Environmental Center.  The beer tasting is only open to attendees of the work day who are 21+. Space is limited and registration is required. This event was rescheduled from 10/27.

Saturday, 12/1 - Intro Meeting for the Wissahickon Birding Club

Saturday, 12/1
10 – 11 am
Valley Green Inn, Club Room

As a natural outgrowth of the new Ecological Land Management Plan and spurred on by long-term FOW member, former Board member and avid birder Shirley Gracie, FOW is launching a birding club to monitor bird species in Wissahickon Valley Park. Please join us for the first introductory meeting on Saturday December 1st at 10am in Valley Green Inn. Space is limited, so please register early.

So many park visitors love to watch and follow the comings and goings of birds in the Wissahickon, an important stop on the Atlantic Flyway. It is our hope that members of the Birding Club will share their observations in our database. Information collected by this group will help inform future habitat restoration and land management activities in the park.

Registration Link Coming Soon!
