Washington Road crosses over Stony Brook here, and it's a great place to stop and enjoy the view. The wide shoulder and sidewalk along the side of the bridge allow you to stop safely without worrying about oncoming traffic.

This historic district has so many stories to tell, starting with the Lenni Lenape Indians that originally occupied this area. Many of their artifacts have been found in this area, along with signs of early European settlers and 18th-century agriculture.

Built in 1907 at the meeting point of Stony Brook and Millstone River, the Lake Carnegie dam created the lake enjoyed by rowers and the community. After a century of upkeep, repairs were needed again in 2015. This is a great place to watch races.
