Belle Isle Marsh Reservation

Belle Isle Marsh Reservation is a coastal wetland nature reserve in East Boston covering 350 acres of salt marsh habitat with native plants and diverse wildlife. The property includes marked walking trails, an observation tower, and designated parking areas for visitor access.

The land was granted to William Brereton in 1628 when it was called Susana Island and later became known as Hog Island before taking its current name. This site was preserved because it represents one of the last remaining salt marshes in the Boston Harbor area.

The name Belle Isle refers to the island-like shape formed by the surrounding waterways and marsh channels. Visitors can observe how birds nest in the reeds and how local people use the trails to connect with this remaining coastal habitat.

The reservation is open daily from sunrise to sunset with parking available at Bennington Street. Bring binoculars and wear appropriate clothing for wet and windy conditions, as the site offers bird watching opportunities throughout the year.

The marsh stores carbon in its soil and acts as a natural shield against coastal storms, though few visitors realize this hidden environmental value. This ecosystem service makes the site far more important than its modest appearance suggests.
