Built in 1834, the Kingston Lock was initially constructed to enable safe and efficient freight transport between Philadelphia and New York. These days it is a historic landmark along the D&R Canal Towpath.

Carnegie Lake, stretching across parts of central New Jersey, owes its existence to an unusual encounter: a conversation between a painter and Andrew Carnegie. Built in the early 1900s for Princeton’s rowing team, the lake quickly became more than just a training site. Locals fish here, paddle, or stroll along the quiet banks. Pollution has taken its toll, but efforts to clean the water are ongoing.

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.
