About this site
Duck Island lies off the coast of New Hampshire in the Isles of Shoals, a small island group that straddles the New Hampshire and Maine state line in the Gulf of Maine. The surrounding waters are marked by granite ledges and rocky bottom typical of this part of the New England coast, reached by boat from nearby harbors such as Portsmouth or Rye.
