Odiorne Point State Park

Odiorne Point State Park offers one of the most beautiful natural settings along New Hampshire’s 18-mile coastline.

Odiorne Point State Park

Within the 135-acre seaside park, visitors can enjoy expansive views of the Gulf of Maine, including four lighthouses, the Isles of Shoals, the mouth of the Piscataqua River, and the southern coast of Maine. Visitors can also enjoy:

  • Picnic areas, grassy fields, a playground, and miles of walking trails, many of which are handicapped accessible.
  • Seven distinctly different natural habitats, including woodlands, uplands, a salt marsh, freshwater and salt ponds, a sandy beach, and the rocky shore.
  • Historic fortifications from the time the property was Fort Dearborn, built to protect Portsmouth Harbor during WWII.
  • Remnants of an era gone by, including old stone walls and cellar holes from the property’s grand estate years.

New Hampshire Division of Parks and Recreation operates the park; Seacoast Science Center provides educational experiences at Odiorne Point State Park on behalf of New Hampshire State Parks. Visit
