At the Upper Main Line YMCA, we build environmental literacy through top-notch nature and STEM programming for all ages. The Cassatt Preserve, barnyard, nature center, raptor center, stem labs, watershed lab, archery course and our team of 30 ambassador animals allows us to engage students on many levels and create lasting connections with the natural world.

Many of our programs are featured below, but if you're interested in learning more about our opportunities for Scout Groups, overnight campouts, Zoo on Wheels or field trips, inquire today!
