PARK AFTER DARK: Moonwalk + Stargazing Party

Join us for a moonlit hike and telescope observation!


Tuesday, October 15


6:30 pm - 8:30 pm


Lemon Hill Mansion

Lemon Hill Drive
Philadelphia PA, 19130

Join Fairmount Park Conservancy and astronomer/educator Buddy Muhler for a two-mile guided moonwalk and telescope observation. 

We’ll start by using the moonlight to guide us on a short hike along the Lemon Hill Rim Trail a wooded trail that runs high above Kelly Drive and offers some views of the Schuylkill River below. Learn a little about the history of the area as well as the nocturnal animals that call the forest home.

Next, we’ll turn our attention to the moon itself by ending the hike with a guided moon and planet or star observation, depending on the month. Novice and experienced astronomers alike will be given insights and tips by experienced instructor Buddy Muhler. Each attendee will have the chance to travel close up to the moon’s surface by looking through Buddy’s high-powered telescope! Buddy will discuss the lunar cycles and point out interesting visible surface features such as dark gray mares (seas) and white reflective highlands. We’ll gaze at planets or stars and discuss other astronomical wonders of the night sky.

If you’re a lunar lunatic, this is an evening not to miss!

Estimated distance: roughly two miles
Level: easy to moderate
Terrain: combination of flat open parkland and hilly trails
