Join our volunteer community—a diverse, welcoming group that supports our mission to protect and steward the Wissahickon Valley. We provide a variety of opportunities to get involved, no matter your schedule. Choose a program based on your skills, interests, and availability. Some positions are seasonal, require attendance at training workshops, and/or hands-on training. Explore volunteer positions below and apply online to get started. 

COVID-19 Update

The safety of our community is our priority. Due to COVID-19, all volunteer activities are suspended until at least April 30, 2020. Please be sure to fill out a volunteer interest form and we will reach out to you when volunteer operations resume. We greatly appreciate your continued support.


Our trails remain open for day use and we hope the community finds respite along the Wissahickon. Visit the Department of Health’s dedicated COVID-19 webpage for up-to-date information and guidance regarding COVID-19 in Pennsylvania. 

Education Program

Assist local students in learning about the natural environment. In the fall, you’ll work with elementary school students at the Evans-Mumbower Mill as they learn about simple machines and the history of water-powered mills. In the spring, you’ll assist high school students at the Wissahickon Creek as they learn about water quality. As a volunteer, you will help lead students in lessons. Previous teaching experience is a plus but not required—we provide training, and assistance in obtaining clearances for working with kids.



Sessions take place during the school day and are concentrated within a few weeks in the spring and fall. Typically, three hour sessions are held both in the morning and afternoon. 


Get started.

Evans-Mumbower Mill

Share your passion for history and education at the Evans-Mumbower Mill. Open House volunteers operate the mill eight times a year for the public to enjoy. Maintenance volunteers help preserve the mill through maintenance jobs, improvement projects, and carpentry in the historic structure. 



4 hours a month (generally third Sunday, April through December). If interested, you can also help with school group visits during the fall.

You’ll offer handouts and event information, and get neighbors excited about volunteering with and donating to Wissahickon Trails.
