Finns Point is a small strategic promontory at the southwest corner of the New Jersey peninsula, on the east bank of the Delaware River near its mouth on Delaware Bay. Due to a geographic curiosity, part of the promontory is actually enclosed within the state of Delaware's borders, due to tidal flow and the manner in which the borders between New Jersey and Delaware were first laid out. The area is about 10 miles south of the city of Wilmington, and directly across the Delaware River from the New Castle area, and the Delaware River entrance to the Chesapeake & Delaware Canal.
