Things to Do on Plum Island, MA
Plum Island offers a concentrated range of activities oriented around wildlife, coastal recreation, and New England maritime heritage. The following are the primary activities drawing visitors and residents to the island year-round.
1. Parker River National Wildlife Refuge
The refuge covers approximately 4,700 acres of barrier beach, dunes, salt marsh, and freshwater impoundments. It is one of the most productive birding sites on the Atlantic flyway, recording over 300 species annually including shorebirds, raptors, and migratory waterfowl.[1] The Hellcat Interpretive Trail offers a 2-mile loop through marsh and upland habitat with designated observation platforms. The refuge also includes boardwalks leading directly to Plum Island Beach.
Parker River National Wildlife Refuge
Address: 6 Plum Island Turnpike, Newburyport, MA 01950
Hours: Open daily, dawn to dusk (visitor center hours vary seasonally)
Entry fee: $5 per vehicle (subject to change; verify at fws.gov before visiting)[2]
Seasonal note: Beach sections are closed during piping plover nesting season (typically April through August in nesting zones)
2. Plum Island Beach
Plum Island Beach is a natural barrier beach stretching the length of the island's Atlantic-facing shore. The northern section, accessible via the Plum Island Turnpike parking areas, is the primary public beach. The beach is well-regarded for surf-casting (striped bass, bluefish), kite flying, and uncrowded swimming conditions relative to closer Boston-area beaches. Lifeguard coverage is seasonal and limited; check current status with the Newburyport harbormaster before visiting with young children. The beach faces northeast and catches consistent onshore wind, making it popular with kitesurfers in season.
3. Kayaking and Paddleboarding — the Back Side
The sheltered back side of Plum Island, bordering the Plum Island Sound and the extensive salt marsh system, provides some of the best flatwater paddling on the North Shore. Kayakers access the sound via launch points in Newburyport and Newbury. The marsh system supports blue herons, snowy egrets, and osprey year-round, making this a productive wildlife observation route as well as a recreational one. Guided kayak tours operate seasonally out of Newburyport; contact local outfitters for current scheduling.
4. Plum Island Lighthouse and the Pink House
The Plum Island Lighthouse, first established in 1788 and rebuilt multiple times, is located at the northern tip of the island adjacent to the mouth of the Merrimack River.[3] The light remains an active aid to navigation. The nearby Pink House — a colonial revival structure with a distinctive pink exterior — is one of the most photographed landmarks on the North Shore. Both are accessible from Sandy Point State Reservation at the northern tip of the island.

Living on Plum Island: What Buyers Need to Know
Plum Island is a year-round residential community, though the population swells significantly in summer. Year-round residents number in the hundreds rather than thousands, giving the island a genuine small-town character that is difficult to replicate elsewhere on the North Shore. Key considerations for buyers include:
Flood zone and coastal resilience: Most of the island falls within FEMA-designated flood zones. Buyers should review current flood map panels and obtain an elevation certificate for any property before purchase. The MA FY2026 Shore Protection Strategy includes dune nourishment efforts along the Plum Island shoreline — verify current project status with the MA Office of Coastal Zone Management before relying on specific timelines.[4]
MA Inspection Law (760 CMR 74, effective October 2025): Sellers on Plum Island cannot accept offers that waive inspection rights under current Massachusetts law. Buyers should budget for a full structural inspection including moisture and coastal foundation assessment for any island property.
Property taxes: Plum Island properties fall within Newburyport or Newbury tax jurisdictions. The Newburyport FY2026 residential rate is $9.28 per thousand of assessed value, with an average Newburyport single-family assessment of approximately $1,106,800.[5]
