Seacoast Region (New Hampshire) Information
The Seacoast Region is the southeast area of the U.S. state of New Hampshire that includes the eastern portion of Rockingham County and the southern portion of Strafford County. The region stretches 13 miles (21 km) 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 alternates between rocky and rough headlands and areas with sandy beaches. Some of the beaches are bordered by jetties or groins, particularly in the towns of Rye and Hampton. The Seacoast Region includes some inland towns as well, as far west as Epping and as far north as Rochester.
The city of Portsmouth is the cultural and commercial hub of the region, with numerous historical landmarks and tourist attractions including Strawbery Banke, the Moffatt-Ladd House, and the John Paul Jones House. Dover in Strafford County is the largest city in the region by population and is the oldest permanent settlement in New Hampshire. Dover is home to the Children's Museum of New Hampshire  and the renowned Woodman Institute Museum. The Seacoast Region was the first area of the state to be permanently settled by Europeans in the early 17th century.
Straddling the maritime border New Hampshire shares with Maine are the Isles of Shoals - White, Seavey, Lunging, and Star Islands. From Portsmouth, they are a short ferry ride out into the Gulf of Maine.

New Hampshire Route 1A runs along the ocean shore, while U.S. Route 1 runs in a parallel direction slightly farther inland. During the high tourist season, these highways are crowded with day tourists and seasonal renters. Slightly farther inland, Interstate 95 (the Blue Star Turnpike) carries most of the through traffic between Maine and Massachusetts, while NH Route 101 carries New Hampshire's east-west traffic between the Seacoast Region and the inland portions of the state. The Spaulding Turnpike (NH 16) originates in Portsmouth and travels north through Dover and Rochester, connecting the Seacoast with New Hampshire's Lakes Region and White Mountains Region.
Amtrak's Downeaster stops in three Seacoast communities - Dover, Durham–UNH, and Exeter- with service to Boston's North Station and Portland, and points north. The Downeaster also stops in nearby Wells, Maine.
