Cold Brook Nature Preserve - Guide and Trail Map


Van Doren Farm at Cold Brook ReserveCold Brook Reserve is comprised of 180 acres of Hunterdon County parkland, along with 111 acres of conservation easements on privately owned properties with no public access.

Benjamin and Emma Van Doren purchased the majority of the property as farmland in the 1850s, and planted 5000 peach trees. Their son John switched to dairy operations around 1900 and had the first farm in the area that installed milking machines. In 1955, John Jr. took over the farm, and planted 400 apple trees in addition to other crops. In 1973, the farm was
sold to Malcolm and Miriam Klein. The property was acquired from a developer by the New Jersey Conservation Foundation (NJCF), who added additional acreage and ensured its preservation. The property was subsequently purchased from NJCF and added to the Hunterdon County Park System, in 1984.

AGRICULTURAL USE In keeping with Cold Brook’s history, the County contracts much of the land to a local farmer. In accepting the agreement, the farmer has agreed to farm the property while complying with a management plan. Please be considerate. Stay on the trails and do not pick or damage any crops.

Wildlife at Cold Brook ReserveWILDLIFE The fields of Cold Brook offer a wonderful opportunity to view and find evidence of some of the County’s predators. Scan the skies to see if any raptors are hunting in the area. Red-tailed Hawks are common and Northern Harriers have been known to reside here during the winter season. While walking the trails, look for scat and tracks of coyotes and foxes. There is an abundance of edge habitat throughout Cold Brook. The field edges provide shelter to several birds throughout the season. Some of the species sighted Brown Thrashers and Fox Sparrows, in addition to other unusual sparrows. Small mammals, such as rabbits and skunks, also take advantage of this terrain.

Old debris and wood piles, which are scattered about in the old fence rows and tree lines, provide excellent habitat for snakes. Potential sightings include Black Rat Snakes and Eastern
Milk Snakes.

Recreational Opportunities at Cold Brook ReserveRECREATIONAL OPPORTUNITIES Cold Brook offers many forms of recreational activities. Visitors can hike over two miles of easy trails. The trails take advantage of existing farm roads and field edges. Horseback riding, cross-country skiing, and mountain biking are permitted on the trail system. Visitors are exposed to a variety of habitats along the trail which include meadows, wooded areas, edge habitat, and a small drainage pond.

HUNTING In order to control the population of deer on park property, hunting is permitted. Hunters must obtain a special permit issued by the Parks Division to be able to hunt on the preserve. Visitors during hunting season are strongly encouraged to wear blaze orange or confine visits to Sundays. See additional information on the Hunterdon County Park System Controlled Hunting Program.

With the exception of park properties with reservable facilities, all properties are “carry in / carry out” and trash/recycling receptacles are not provided.  Please plan accordingly and do not leave any trash/recyclables behind.
