Welcome to the New Hampshire Seacoast Greenway: the ECG in NH

The New Hampshire section of the East Coast Greenway is the shortest of all states along the Greenway – only 16 miles! It is known as the New Hampshire Seacoast Greenway. Currently, the entire route is on road, but plans are in the works to create an entirely off-road rail-trail from the Massachusetts border to Portsmouth.

Travelers enter New Hampshire from the north along a road-separated bike/ped walkway over the Memorial Bridge. From there, the route hugs closely to the coast for entire trek through the state, offering continuous views of the Atlantic unparalleled in any other ECG state north of Florida, including of the historic Isles of Shoals. Most of this on-road route has a shoulder, but some sections do not.

Trail Status & Plans

None of the New Hampshire route is off-road today, but several miles of abandoned railway are pending development. The NH spine route will total 17.2 miles, and we anticipate virtually all of it will use the corridor of the Boston and Maine Railroad from Seabrook to Portsmouth. This RR ROW crosses into Massachusetts and is being advanced there as a trail. The southernmost portion of this ROW in NH (4.5 miles) was acquired by the State of New Hampshire Department of Transportation when it was abandoned as a rail corridor, including the section passing through the Seabrook Nuclear Power Plant. The northern section (11.5 miles) is owned by Guilford Industries, which has filed for abandonment and is presently negotiating sale of the land to the State of NH, for conversion to trail. In Portsmouth, the East Coast Greenway leaves the railroad ROW and uses an on-road route to reach Memorial Bridge where it crosses into Maine.
