Saturday August 2, 2025
9:30 AM - 3:00 PM

Join us at our 25th annual Watershed Butterfly Festival – an in-person celebration of family fun to share the joys and wonders of nature. The event will feature tours of the Kate Gorrie Butterfly House and the Insect Zoo. Enjoy live music from the Cold Soil Drifters and entertainment throughout the day, including animal shows featuring Eyes of the Wild and performances from Sprout U School of the Arts. Young children will delight in being a part of the famous “Butterfly and Bug Parade” led by Lady Monarch, Ms. Allison. Adults and older children can learn about watersheds and the need to protect our rivers, lakes and streams through educational hands-on exhibits. Food and drink will be available for sale and don't forget to bring your reusable water bottle to fill up at the New Jersey American Water H2O On The Go Van. Butterfly wings and other fun items can be purchased at the Watershed Gift Shop.
