A slight drop in the Delaware River creates a low waterfall shelf that is a popular spot for kayaking and fishing. A parking lot and lookout area can be found just off of the D&R trail. When water levels are high it is possible that the falls disappear under the surface, but you still get a great view of the river.

This short bridge over the canal takes you to a rebuilt home from 1799 that now functions as a restroom with water fountains and air conditioning. This is a great little scenic rest stop along the canal trail.

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.
