- Picnic tables
- Scenic overlook
strategic location of Washington Rock made it
a valuable lookout point during the American
Revolution for General George Washington in
June of 1777 when the British army under General
William Howe was moving toward Westfield. From
the vantage point of this natural rock outcropping,
General Washington had a thirty-mile panoramic
view of the valley and was able to instruct
his troops to circle behind Howe’s troops
and cut off their retreat.
One of the oldest state parks in New
Jersey, Washington Rock was originally purchased in 1913 to
commemorate the historical events of 1777. Situated on top
of Watchung Mountain in Green Brook Township, the park is
best known for its scenic vista and historical significance.
The park is a popular site for picnicking and relaxing.
Washington Rock is currently being managed by the Somerset County Park Commission. For more information contact: (908) 722-1200.
