Oakdale, NY
3,473 acres

The largest state park on Long Island, Connetquot is an historic and scenic oasis amid surrounding suburban clutter.


Take the Belt (Cross Island) parkway to exit 25A. From there, go east about 34 miles on the Southern State parkway to exit 44. Turn onto Sunrise Highway going east; the park entrance is 1.3 miles further east, on the left. (You have to drive to exit 47A and then turn around and come back because the park entrance is only on the west bound side.)


The Connetquot River goes through the preserve.


This is Long Island's largest state park. It is named for the Connetquot River, which runs through the preserve. Connetquot was the Indian word for "at the long river."

Montauk Highway was once the road used by the Secatog people. It was located at the first shallow ford (water crossing) north of the Great South Bay where the streams could be crossed on a fallen tree.

mid-1700s -- the Oakdale Grist Mill here was built by the Nicoll family, founder of the town of Islip. In 1972 it was placed on the National Register of Historic Places.

The land was held by a syndicate of never more than 100 wealthy sportsmen as a private trout stream and hunting preserve for more than a century. Some of the famous men who came here were Daniel Webster, Ulysses S. Grant, General Sherman, Lorenzo Delmonico, and Charles L. Tiffany. Made available to the public in 1978.

The Main House here was originally Snedecor's Tavern (built around 1820). It was later the clubhouse of the South Side Sportsmen's Club of Long Island (1866-1973). It is now used as the New York State Regional Environmental Education Office and Interpretive Center.

1970s -- opens to the public.

(Cynthia Blair, Newsday Names of Long Island;


Pitch pines and oaks line the tranquil river and fill the adjacent woodland. Pitch pines and white oaks are the dominant trees in this sandy soil, which is characteristic of the glacial outwash plains. Pitch pines are considered by some ecologists to be indicator plants for the so-called sand-plain community. Their especially deep root system penetrates the dry, porous ground to help them extract as much moisture as they can. They are the prevailing tree in the pine-oak barrens of Suffolk County which extend from here all the way to the eastern end of Long Island. However, white oaks are perhaps the most common tree found on Long Island, according to the Long Island Horticultural Society. The larger specimens are found not here but almost exclusively in the richer soils of the north shore.

The continental glaciers that descended upon New England stopped a few miles north of Connetquot, leaving their mark in a jumble of small hills known as the Ronkonkoma Terminal Moraine. The area south of the glacial edge on which Connetquot is located is known as an outwash plain, a gently sloping flattish zone composed of sand and gravel deposited by the glacier's meltwater. As these meltwater streams lost their velocity, they dumped enormous loads of debris, which became the broad plain that makes up the southern half of Long Island.


You have to get a permit when you arrive. The Long Island Greenbelt Trail, part of the National Recreational Trail System, passes through the preserve for a distance of about four miles.

Cross the dam on a blacktop road and turn left about 150 yards further onto the red trail After a short walk find an overlook at the pond's edge. This 15-acre body of water was created in about 1750 as a reservoir to power a grist and cloth-fulling mill. The mill, located downstream a bit, is listed on the National Register of Historic Places and is open to the public. Since the pond is only a few miles from Great South Bay, many bay ducks, such as canvasback, redhead, greater and lesser scaup, and bufflehead are common.

A small fishing dock marked with a number 8 leads a few yards into the Connetquot River itself. A layer of glacial pebbles covered with dark silt makes up the shallow bottom. The Connetquot begins as a spring-fed seep several miles to the north. As the water is a cold 52 degrees when it emerges from the underground aquifer, it is particularly well suited for trout. Brook trout are native, but browns and rainbows have been introduced.

Continue on the red trail, past a small building on the left, to the yellow trail. Go left toward the river and the trout-hatchery complex. Continue to the right along a small pond as the yellow trail cuts left. Cross a wooden bridge, marked 20a, that separates an upper and a lower pond. If you are here in the fall, winter, or early spring, you may well see the great blue herons that winter at the far end of the upper pond. Approximately thirty to forty individuals spend the colder months in this spot where fish are plentiful before leaving fro breeding grounds in late April and early May. Exactly where these herons go is not known. However, one can be fairly sure they do not nest on Long Island.

Cross another bridge to a sandy road and walk left toward a trailer and building. Pick up a dirt path that parallels the paved road just past the last structure.

The terrain changes quite dramatically at D, for here the area looks barren, desolate, scrubby, and open. In 1977 a fire swept through 600 acres here, decimating all but a few of the hardier, taller pitch pines. Young white, black, scarlet, and scrub oaks and high and low-bush blueberries are rising from the poor soil Notice also the small pitch pines trying to regain their lost territory. Pitch-pine seeds are unusual in that they can germinate on sterile mineral soil containing no humus at all. The ability to sprout from dormant buds at the base of burned trunks also allows these hardy trees to regenerate after a fire.

Continue along the path until you meet a paved road, with a large open field to the left. Go a short distance and take the left fork toward the buildings and the millpond.

Walking time is about 1.75 hours and is relatively easy. There are many other trails that cover different areas in this large preserve. Camping at nearby Hecksher State Park in East Islip.
