A hilly, forested 794-acre site overlooking the Navesink River, this park is among the highest elevations along the Atlantic Coast and features prominently in area history as a former coastal defense site. Known for its challenging trail system and scenic views, Hartshorne Woods is a popular park for area hikers, bicyclists and outdoor enthusiasts.
Park features: group cabin camping (by reservation), cross country ski trails, fishing in the Navesink River and trails for walking, hiking, biking, and horseback riding. It's the perfect place to escape the sounds of suburbia.
Please be aware that NJ anglers age 16 and up are now required to register with the NJ Saltwater Angler Registry (for free) to fish in marine and fresh tidal waters of NJ. For more information regarding the registration, click here.
This park is named after Richard Hartshorne an English Quaker from London who settled here in 1669 and acquired more than 2,300 acres of land. By the early 1880s, some of the land was sold to private individuals and the U.S. government, but large portions remained in Hartshorne family ownership.
The Park System acquired the first 660 acres of this park in 1974. Additional land was conveyed from the government in 1984, and subsequent purchases – including the 44-acre Claypit Creek section in 2005- brought the park to its current size.

The Hartshorne property was a desirable defense site because of its high elevation. Through the years, it hosted a number of different land and air-based military installations to defend New York Harbor and surrounding areas.
During the WWII era, batteries for heavy artillery were built on this site to modernize coastal defense efforts. These concrete and earth encasements or bunkers – considered “bomb-proof” at the time – protected personnel and equipment. These structures can still be viewed today.
With the rise of strategic air power and nuclear weapons, the reliance on artillery guns for coastal defense ended. During the Cold War Era, from the 1950s-1970s, the site served as a missile defense site and command center with radar, computers and electronic plotting devices. Structures from this era have all been removed.
On October 13, 2015, the Navesink Military Reservation Historic District – all 224 acres of the former military base – was officially listed on the National Register of Historic Places.
Gun Barrel Delivery
The Monmouth County Park System is pleased to announce that a historic World War II naval gun from the Battleship New Jersey has arrived at Battery Lewis in Hartshorne Woods Park. It will be on permanent display as part of the Battery Lewis restoration. The gun barrel, which is 68 feet long and weighs 120 tons, is almost identical to the 16-inch guns on Battery Lewis during World War II.
Originally on the USS New Jersey and donated by the U.S. Navy to the Monmouth County Park System, the gun barrel travelled by rail from Norfolk, Virginia to Red Bank and then by truck to Hartshorne Woods Park. It is in a temporary position next to Battery Lewis. Once restoration of the gun barrel is completed and a pedestal is constructed, it will then be moved to its permanent location in the battery casemate.
