2026 Butterfly Festival

August 1, 2026

Annual Watershed Butterfly Festival

Join us for a fun-filled family celebration to explore the wonders of nature! Adults and children can learn about watersheds and the importance of protecting our rivers, lakes, and streams through engaging, hands-on exhibits. Food and drinks will be available for purchase, including water provided by New Jersey American Water, and visitors can shop for butterfly wings and other fun items in our Gift Shop. This annual event celebrates butterflies and other insects while encouraging everyone to get outside, connect with nature, and have fun together!

For this year’s Butterfly Festival, we will have one all-day session. Guests are welcome to join us anytime between 9:30 a.m. and 3 p.m. at The Watershed Institute, located at 31 Titus Mill Road, Pennington, NJ 08534.
