Join Fairmount Park Conservancy and Andrew Kirkpatrick, Urban Greening Coordinator with Parks and Recreation’s Farm Philly Program, for a 1.5-mile tree identification hike around Concourse and Centennial Lakes in West Fairmount Park.

From sweetgums to tulip poplars to a variety of oaks— our urban landscapes are teeming with a variety of tree species. Concourse Lake, in particular, is a dedicated 14-acre Native Plant Park with over 100 trees from roughly 25 different species. On this hike, we’ll learn to identify trees based on leaves, branches, and bark. We’ll take time to observe the body language of trees, why they grow the way they do, and what we can learn about the life of the forest.

This hike is part of our Second Saturday Guided Hike Series. These hikes occur from 10 AM–12 PM on the second Saturday of every month (April–November). Second Saturday hikes are at various locations.
