Trailside Nature & Science Center is Union County’s Environmental Education Center, located in the Watchung Reservation, a 2,065-acre preserve containing woodlands, fields, lakes, streams and more than 13 miles of hiking trails.

This serene setting provides the perfect classroom to have fun while learning about the natural world. Renovated in September 2006, the Center houses 4,500 square feet of interactive, state-of-the art exhibits, including a towering 34-foot American beech tree exhibit that fills the building’s atrium.

This jewel, secluded in the Watchungs, also features classrooms that look out on the Reservation, a multipurpose room, a library, children’s discovery room and a 250-seat auditorium.
