Turn right (north) onto West Neck Road (which becomes Lloyd Harbor Road); go 7.4 miles. The refuge is on the right side of the road.


There are two large boulders just offshore that were once just part of the general glacial residue (the land around them eroded away). During the Revolutionary War, British warships used the larger rock as a gunnery target -- hence the name.

In 1967 Ferdinand Eberstadt (1890-1969), a Manhattan investment banker of the Princeton Class of 1913 and genius of American mobilization during World War II, built here a 35 room neo-Georgian mansion in 1937 on one of the higher points of land. After his death, the property was donated his estate to the United States Department of Interior with the understanding that it be preserved as a wildlife refuge and center for environmental education.


Salt marsh, a pond, tidal waters, a thicket, and interestingly, formal gardens. Because of the diversity of the habitat, 191 species of birds have been identified at the refuge.


A guide pamphlet of the one-mile nature walk is available at the refuge. There is a one-mile loop trail through mature oak-hickory woods. There is a quarter-mile spur down to the beach.
