Bridgehampton, NY
87 acres


Take the Belt (Cross Island) Parkway to exit 25A. From there go east about 83 miles, first on the Southern State Parkway to exit 44, then on Route 27 (which starts as Sunrise Highway, but changes name). At the traffic light in Bridgehampton, turn south (right) onto Ocean Road and go 0.3 mile. Turn left onto Sagaponack Road; go 0.7 miles to a Nature Conservancy sign on the left. Park on the grass in front of the preserve, but not on the south side of the road.


Sagg Swamp is the largest remaining red-maple swamp on Long Island, east of Riverhead. Twelve varieties of ferns, three stands of Atlantic white-cedars, and a wide diversity of shrubs, sedges, rushes, vines, and wildflowers make this 84-acre wetland a botanical haven. A small kettle pond supports muskrats, turtles, several species of duck, and other wild creatures.

Jeremy's Hole, a small kettle pond to the right; oak upland; marsh

Sagg Stream enters Jeremy's Hole to the north and leaves to the south, heading into Sagaponack Pond and the nearby Atlantic Ocean. Poxabogue Pond, half a mile to the north, is the main source for the swamp, supplemented by rain runoff and a few small feeder streams.


The trail begins at the southwestern portion of the property. Water-proof boots may be helpful.

9/15/02 -- Patrick and Rosemary Cooney, Judith Fitzgerald, and Lenore Swensen walked this area. There is a yellow trail marker, but not really needed as there is only one trail basically that takes the hiker through dense walls of vegetation (with lots of sweet pepperbush) to a boardwalk that goes through a swamp. There is some atlantic white cedar and poison sumac here.
