Hoffman Park - Guide and Trail Map



The Crystal Springs Preserve is comprised of 233 acres of mature forest, active farmland, meadows, ponds, and the headwaters of the Spruce Run in Hunterdon County. An additional 58 acres of this property exists in Washington Township, Morris County, and is maintained by the Washington Township Land Trust.

The park’s name is derived from the mineral springs found in the area. These springs are high in iron content and know as chalybeate springs. In 1815, officials declared chalybeate springs to be the purest source of water. This led to the creation of one of the earliest resort and spa communities in the country, which was located on nearby Schooley’s Mountain in Washington Township.

Crystal Springs Preserve was acquired through a multi-agency partnership in 2004 that involved New Jersey Water Supply Authority, Hunterdon Land Trust Alliance, Washington Township Land Trust Alliance, Township of Lebanon, New Jersey Division of Environmental Protection, and Hunterdon County.

AGRICULTURAL USE 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.

HABITAT AND WILDLIFE Crystal Springs Preserve surrounds the headwaters of the Spruce Run. This creek is one of three waterways that flow into the Spruce Run Reservoir, which is a vital source of drinking water for the county and state. These headwaters are also important to wildlife.

The ponds located within the park serve as a resting point for migratory waterfowl and herons. The water is also home to a variety of amphibians and reptiles. Frogs can be heard calling from the edge of the ponds and turtles can be seen swimming around or basking along
the pond edge.

Beavers are active in and around the ponds, and evidence of beavers is obvious, including chewed trees, dams, and a lodge. The 40-acre meadow located to the south of the ponds is dedicated as grassland bird habitat. It was planted with warm season grass in 2005 and is managed on a multi-year schedule to prevent field to forest succession. The Parks Division hopes that grassland birds such as Bobolink and
Eastern Meadowlark will establish themselves in this meadow.

RECREATIONAL OPPORTUNITIES Crystal Springs offers easy to moderate hiking opportunities. Much of the trail system is composed of pathways along the edge of the fields. A connector trail links up with the Teetertown Preserve.

FISHING Five ponds are located on the property and are the headwaters of the Spruce Run. Anglers can fish for a variety of species, including bass, catfish, and sunfish. Ponds are designated for catch and release, and State Fish and Wildlife rules apply.

HUNTING In order to control the population of deer on park property, hunting is permitted. Hunters must obtain a special permit issued by the Division to hunt in the park. 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.
