Park Details

Situated at the headwaters of the Nissequogue River, this 627 acre park offers visitors panoramic views of Stump Pond, miles of trails, and a wide array of cultural & recreational activities.

Stump Pond was created in 1798 when Isaac Blydenburgh, along with his cousins Joshua Smith II and Caleb Smith II, dammed the headwaters of the Nissequogue River in order to construct a grist mill. The dam flooded the river’s original banks to form a pond. Tree stumps on the former banks protruded through the water which is how Stump Pond got its name.

Since the construction of a boardwalk through swampland in the southwest region of the park, hikers are able to walk a 5.7 mile loop trail around the entire pond. The trail is blazed with either white or blue arrows. Guided hikes are periodically offered by the Long Island Greenbelt Trail Conference whose headquarters are located inside the park. Guided tours of the Blydenburgh Farm and New Mill Historic District , the 19th century settlement established by the Blydenburgh family, are also offered at 1:00 PM on Saturdays. For more information about hikes and tours call (631) 360-0753 or visit http://www.ligreenbelt.org/.

Other activities at the park include, camping, fishing, boating, kayaking, horseback riding, picnicking, and use of the dog run and playground.

A map of the park can be downloaded using the link on this page. For his Eagle Scout project, Jacob Gaio from Troop 888 Smithtown created this map, replaced trail blazes, and installed numbered trail marker posts with QR Codes that enable anyone with a smartphone to download the map and find their location. The map is also available for free download in the Avenza Maps app.
