Parks After Dark Programs

The Parks After Dark Science Programs are guided educational experiences designed to help participants understand the value of the night sky, natural darkness, and the importance of nocturnal species in our environment.

For many years, light pollution has been increasing worldwide and continues to grow rapidly. The lightening of our night skies affects a wide range of natural resources, including nocturnal species at Valley Forge National Historical Park.

During Parks After Dark events, attendees will gain first-hand experience in natural resource management by participating in citizen science and inventorying target nocturnal species. Events will take place during the summer of 2024 and highlight different nocturnal species, ensuring that each event is a unique, educational experience. Registration is required for the August 17 Night Hike
