Heathcote Brook Road, Kingston, South Brunswick Township, Middlesex County
26 acres 
managed by Delaware and Raritan Canal State Park


Rt. 1 to Ridge Road west; parking area approx. 0.9 mile on right, just beyond Heathcote Brook bridge.


c. 1865  --  a stone bridge built to carry Ridge Road over Heathcote Brook.

1937  --  the picturesque old stone bridge was re-erected in its present site in the middle of the natural area.

1970  --  Grace Cook of South Brunswick donated the area.


freshwater marsh and floodplain forest communities, small ponds


The short trail (1/2-mile to 1 mile) goes over a historic bridge crossing the Heathcote Brook.

The abandoned Conrail line green belt crosses the Delaware and Raritan Canal Park and is being acquired up to the Cook Natural Area by the state. The Township of South Brunswick plans to acquire the portion from there to the Town Center with Green Acres funds. (

One can walk from the Cook Natural Area to the Kingston lock, over the old stone bridge and on to Heathcote Park. This whole section forms part of the "Freedom Trail".

A long walk of 7-8 miles would go through Heathcote Park, Linear Park, Cook Natural Area and along the Delaware & Raritan Canal. (Highlights could include the Kingston Locks, the Grotto, the town of Kingston and the former Princeton Nurseries land including the deserted "Cry Baby Lane".)


Delaware and Raritan Canal State Park


There is a small parking area for six cars or so. There is a long alleyway between the woods on the right and a tree border on the left. The alleyway is somewhat of a moist/wet meadow with lots and lots of purple loosestrife being the dominant plant.

There is a pond off to the right. Had to pass in front of a couple in a tent (I said "excuse me"). The guy came out and asked "My wife wants to know if you are an environmentalist or a serial killer." I smiled and said "Oh, a serial killer." He laughed. I told him the names of a few of the plants around and in the pond.

There is a pathway on the right that takes the hiker into the woods over a strange bridge (it has a hump right in the middle of it -- a small arch bridge) crossing over the creek.

Had to slog my way through the purple loosestrife via a narrow deer/few people trail. Only got one tick for my efforts -- not bad.

At the end of the wet meadow is one of the markers denoting a sewer pipline is located below. There is a trail off to the left but I did not travel down it.


Gravel is to be laid along a trail to the canal, so that it will be possible to walk from the Kingston D&R canal lock, through the Cook Natural Area and on over the bridge to the Heathcote Park.
