About this site
Duck Island is part of the Isles of Shoals, a small island cluster off the coast of New Hampshire and Maine at the mouth of the Piscataqua River region, roughly six miles offshore from Portsmouth. The west side of the island would be reached by boat from the New Hampshire seacoast, in the cold, rocky waters typical of this stretch of the Gulf of Maine.
