In Raymond, New Hampshire is a tiny gem of a park laying along the side of the Lamprey River just off NH Route 27. The Lamprey River is a National Wild and Scenic River, a part of the US National Park System. The park has a small pull out off the highway and a short path leads down to the river.
Once down by the river there is one picnic table, a bench right on the river edge and rough hewn paths following the bank of the river in either direction.
Follow the path upstream to the right and you will reach some rapids and a small bridge.
Whether you spend ten minutes or take a picnic lunch this is a nice quiet relaxing spot nestled in the heart of suburbia.
