The Deserted Village of Feltville was founded in 1845 as a mill town by David Felt and was later converted into a summer resort known as Glenside Park.
Lake Surprise was originally created in 1845 to provide water power for David Felt's printing mill.
The reservation contains the 'Blue Brook' which was part of the geological formation of the Watchung basalt ridges.
A portion of the historic Washington Valley is contained within the reservation, documenting centuries of local agricultural and industrial history.
The park maintains a dedicated stable area that connects to miles of equestrian-specific trails.
The Watchung Reservation is a 2,142-acre nature preserve in Union County, New Jersey, serving as the largest park in the county system. It features the historic Trailside Nature and Science Center, which focuses on regional environmental education. The park's topography includes the First and Second Watchung Mountains, offering varied elevation for hikers. Within its boundaries lies the Deserted Village of Feltville, a 19th-century settlement listed on the National Register of Historic Places. Water features include Lake Surprise, a man-made body of water created by damming the Blue Brook. The park contains over 13 miles of hiking trails, including a portion of the Lenape Trail. Diverse habitats range from mature deciduous forests to wetlands and open meadows. The reservation serves as a protected refuge for local wildlife, including white-tailed deer and migratory birds. Visitors utilize the area for activities including horseback riding, picnicking, and fishing.
