You'll feel many miles away from civilization as this rustic 443-acre site in rural Upper Freehold is located amidst the rolling farmland of western Monmouth County. One of the most beautiful parks in the county park system, the property is known for stately stands of red and white oak, beech, ash and birch trees.


Clayton Park Activity Center

In late 2015, the Park System acquired the Imlaystown School on Davis Station Road. Once home to the offices of the Drug Abuse Resistance Education New Jersey, the building is now called the Clayton Park Activity Center and allows the Park System to offer a variety of programs in the park.   

The forested, hilly trails of this park have become a popular destination for hikers, equestrians, and bicyclists. Enter from Emley's Hill Road (6 miles of trails).
