About Seabrook

Seabrook is the first New Hampshire town you hit driving north on I-95, and it leans into that border-town identity with gusto. Route 1 is lined with fireworks superstores — Phantom, Atomic, and half a dozen others — drawing a steady stream of Massachusetts customers who can't legally buy them at home. The town is defined in large part by Seabrook Station, the largest single-unit power plant on the New England grid at 1,244 megawatts, which went online in 1990 after years of construction and massive anti-nuclear protests that saw over 1,400 arrests in a single 1977 demonstration. The former Seabrook Greyhound Park, which opened in 1973 and ended live racing in 2009, was renovated into The Brook, now operating as a casino and sportsbook under New Hampshire's charitable gaming laws. East of the highway, Seabrook Beach is a quiet, no-frills stretch of Atlantic coastline with a tight-knit seasonal community. The town has a blue-collar, independent streak — it does things its own way and makes no apologies for the fireworks-and-power-plant combination that makes it unlike anywhere else in the state.

Hidden Gems in Seabrook

Beyond the well-known attractions, Seabrook has spots that locals love and visitors rarely find.

Historic Brown Library at Seabrook Library

year-round

When Seabrook built its modern library in 1994, residents insisted the beloved 1890s Victorian cottage-style Brown Library be preserved and physically moved to attach to the new building. The original library features wood paneling, a brick fireplace, and warm atmosphere that locals describe as feeling like stepping back in time. Now housing the Historical Society's archives, it's open for visits and maintains the cozy character of a turn-of-the-century reading room that once aimed to raise young men to 'nobler manhood.'

Northern Section of Seabrook Beach

year-round

Hidden behind residential properties along Ocean Boulevard lies a wide, northern stretch of pristine sand dunes that offers quiet solitude even during peak summer. Unlike the developed southern section, this area feels completely secluded with expansive views of marsh meeting ocean. The secret is parking at Harborside Park and walking 15 minutes to access this locals-only feeling paradise that's been ranked as one of the top 100 hidden beaches in America.

Blackwater River Salt Marshes

spring

This 3.1-mile tidal inlet creates the largest salt marsh system in New Hampshire, flowing through pristine marshlands before joining Hampton Harbor. The area provides critical habitat for endangered species like piping plovers and serves as a birding hotspot. Walking the edges during different tidal cycles reveals an ever-changing ecosystem that few visitors discover, with Route 286 offering several unmarked pull-offs where locals quietly observe the marsh life.
