Patterson Environmental Park/Great Swamp
South Street
Patterson, NY  12563


The park is a 23-acre town owned nature preserve situated in the Great Swamp, the second largest wetlands are in New York. The public is invited to hike, fish, canoe, cross-country ski, or just observe nature. Reservations for canoeing required.


Directions:

From the intersection of Routes 22 and 311 (at small green mile marker 11.42), proceed west 0.8 of a mile to South Street (second street on left after crossing the RR tracks). Turn left onto Patterson School/South Street and travel for 0.3 of a mile to a small sign on the left side of South Street (opposite West Street) by a dirt road. I parked in the parking lot of the Carmel Central School District Administration Building across from the dirt road. . The entrance to the Park crosses ungated, unsignaled railroad tracks (use extreme caution). (When I was there a gate was up and locked, accompanied with a message about how to get access to the key by contacting town hall -- hard to tell since the sign was extremely weather-worn.)

The second time I visited the gate was open and I could drive the half mile down to the end of the dirt road.

Call Ahead to the Parklands Caretaker to check navigability of Swamp.

History:

The site is situated on the remains of an old stone quarry and railroad bed. Many of the stones used for the foundations of Patterson homes came from this quarry. The stones were transported by rail into the hamlet. Source: The Nature Conservancy 1996


Trails:

I walked down the dirt road, past the gate, and continued down the dirt road to the river. There was an area on the right with huge rock blocks, probably from the quarry. There is a network of informal, unmarked trails. I was there in the winter and the river was very flooded. The land on the left belongs to a gun club, Patterson Gun Club or something like that. The land on the right is open to the public.

The trails near the river are part of the floodplain and often get flooded. Spicebush appears to be the dominant small tree here. All the trail I follow went in a semi-circle coming back to the dirt road.

Other activities are fishing, mountain biking, and cross-country skiing.
