This Kimpton Brook Trail branches off NH-4A, near Schoolhouse Road. Look for the trailhead sign near the guard rail. It starts by crossing a footbridge over Kimpton Brook. It skirts around the base of a hill, then follows an old woods road for a way. It passes by a pond with a decent view, then ends at Stearns Road.

The Hiking Project website has a description and map of a hike on Kimpton Brook that passes Kimpton Brook Marsh.
