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 of Crystal Springs Section: 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 he 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, including chewed trees, dams, and a lodge, is obvious.
