Upcoming Events

  • BioBlitz!

    This program is canceled.

    8:00 - 10:00 a.m.
    Help WVWA staff identify as many species as we can during this mini-BioBlitz. These surveys of the species on our preserves help us create our land management plants. We will be using the free iNaturalist app to document all of the species that we encounter. Please download the app and set up an account prior to the event. Instructions on how to use the app will be given at the event.

  • Mill Open House & Ice Cream Social

    1:00 p.m. - 4:00 p.m.
    Take a break from the heat and join us for a cool treat and tour the only fully operational gristmill in Montgomery County! Guides will take you for a fascinating tour to see the mill in operation and give you a history of milling on the Wissahickon Creek. This event is free. 

  • Advocacy Workshop

    6:30 - 8: 00 p.m.
    Have you ever wanted to communicate with your local, state, or federal officials but weren't sure how, or what actions would be most impactful? Join us to hear from experts at League of Conservation Voters of PA and learn how to effectively communicate, prepare public comments,  and craft the right message for your elected representatives!

  • Birds & Brews

    6:00 - 9:00 p.m.
    Join us for our 5th Annual Common Nighthawk Migration. The Militia Hill Hawk Watch at Fort Washington State Park spends a few evenings in August each year watching for migrating Common Nighthawks. The last four years, we've managed so see some pretty big flocks pass overhead, so, let’s do it again! After viewing the migrating nighthawks, we will gather at Magerk's Pub for food and brews.
