June 22, 2025, View of Stony Brook from the Bridge

This bridge offers a nice view over Stony Brook, especially at sunset. There’s a lane for pedestrians and bikes, so you can safely stop and take in the scenery. It’s usually not busy so you can even take a quiet brake to enjoy the view.

Stony Brook runs through downtown Princeton while still keeping a quiet atmosphere, with a mostly flat dirt and grass path alongside the water. It’s a great spot for an easy-paced run, walk, or ride with creek views and tree cover.

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.

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.
