Water and wetlands define Winthrop’s identity as “Winthrop-by-the-Sea.” Surrounded by the Broad Sound and Atlantic Ocean on the north and east, Boston Harbor lies to the south and west of town. Winthrop and Yirrell beaches are composed of a mix of sand and rocks. Halford, Short, and Donovan’s beaches appear only as tidal flats when the tide is out.

Salt marshes, remnants of a once larger coastal system, are critical to protecting low-lying portions of Winthrop from storm surges and filtering runoff into the surrounding waterways. Salt marsh brackets Winthrop on the north and south, and scattered patches of marsh ring Winthrop’s coastline. The 241-acre Belle Isle Marsh, which Winthrop shares with East Boston, is the largest remaining salt marsh in the greater Boston area. The much smaller Fisherman’s Bend Marsh, to the south, was recently restored. Both Belle Isle and Fisherman’s Bend are publicly accessible by a mix of formal and informal trails.
• Winthrop’s marshes and beaches were identified by the community as desirable destinations and already contain some walking trails. fisherman’s bend marsh
• Access to the marshes, beaches and tidal flats should respect and preserve the existing ecosystem.
