Located in the southeastern-most corner of Cape Cod, the Monomoy NWR comprises about 7600 acres - the exact size is continually changing as the ocean reshapes the vagile dunes - of pristine dunes, tidal flats, and salt marsh. It is one of the premier birding locales in the entire Northeast, but most of it is either inaccessible or accessible only with considerable effort.
