The Seacoast Region is the southeast area of the U.S. state of New Hampshire. The region stretches 13 miles along the Atlantic Ocean from New Hampshire's border with Salisbury, Massachusetts to the Piscataqua River and New Hampshire's border with Kittery, Maine. The shoreline is generally very rocky and rough in nature, although a few sandy beaches have been created using jetties/groins.
The Isles of Shoals, a short ferry ride out into the Gulf of Maine, are also considered to be in the Seacoast Region and collectively provide five additional miles of coastline in the form of islands: White, Seavey's, Lunging Island, and Star Islands.
