Kings Park, Suffolk County, NY
nearly 153 acres, including 4 miles of waterfront


From NYC take the Belt (Cross Island) parkway to exit 30. From there, go east about 27 miles on the Long Island Expressway to exit 53N. Go north about 3 miles on the Sunken Meadow Parkway to exit SM4, then go east (right). Pass by Main Street and then turn right on St. Johnsland Road.

This is a beautiful park. There are absolutely great views over the coast and the Long Island Sound with many birds to please the birders. You can make a circular walk by walking on the Green Belt Trail switching to walk along the coast and then returning by the Green Belt Trail.


Flowing north for approximately 9 miles, the Nissequogue River crosses the two terminal moraines present on Long Island, and contains freshwater, brackish, and saltwater portions. The lovely river was designated a Scenic and Recreational River by New York State in 1982.

The Nissequogue is one of four major rivers on Long Island, (the others being the Peconic, Carman's, and the Connetquot) and is known for its beauty, its variety of vegetational communities due to the different zones of fresh and salt water.

Meandering through a heavily vegetated corridor, the Nissequogue slowly changes from brackish to saline. The river begins in a series of small tributaries, fed by groundwater and runoff, about 9 miles south from here; it then flows into the second largest lake on Long Island, New Millpond (bordered by a mixed oak-pitch-pine forest). It is the site of an 1802 earthen dam and a nineteenth-century gristmill. New Millpond is contained within Blydenburgh Park.


The archaeological sites discovered along the river corridor include the remains of an Indian village, seasonal camps, flaking stations (points and arrowheads), and fishing and hunting areas. Collected material may be seen in local and county museums.

On November 11, 1999 Governor George E. Pataki announced that more than 80 percent of a former psychiatric center (Kings Park Psychiatric Center) would be preserved as a wooded nature sanctuary and a new state park.


Old stands of oak and other mature woodland; tidal pools; estuaries; freshwater wetland containing an egret rookery.


There are a number of access points to the river. Both canoeists and hikers can get to the river's mouth by driving north on Route 25A for 1.7 miles from the intersection with Route 25, to St. Johnsland Road. Bear right and proceed for 1.8 miles to Old Dock Road. Turn right and follow to dead end, adjacent to Kings Park Bluffs and parking area. Both the canoe rental service and the Greenbelt Trail are here.


The Greenbelt Trail runs perpendicular to the end of Old Dock Road and along the western shore of the river for a short distance. General access to the rive is limited due to local topography and the different land uses in the area. You can walk north, or upstream, for perhaps an eighth of a mile until the trail turns inland; it does not parallel the river again for at least a half- mile. Or you can walk downstream for about a hundred yards into a small park and then follow the trail up steep bluffs that afford a spectacular view of the river's mouth and Long Island Sound.

The dramatic and beautiful scene at the Kings Park Bluffs is quite surprising, given this major river's proximity to the suburbs of Smithtown. The river is several hundred feet wide and flows out to the sound between two sandspits. To the north are bluffs 75 feet high and to the east, across the channel, is Short Beach Park, a federal and state sanctuary for breeding least and common terns. The impact of man is noticeable in the presence of boats and a restaurant and parking lot nearby, but it does not detract from the primal immediacy of sky, sun, sand, and moving water.

Spend some time walking the Greenbelt Trail It will give you good but intermittent views of a very special natural area.

Hikers on this northern section of the Greenbelt Trail need a permit (free) and a map. Permits cannot be mailed. Closed on Mondays.
