South Boston - Castle Island

2010 Day Boulevard

Fort Independence, a pentagonal five-bastioned, granite fort built between 1834 and 1851, is the dominating feature of Castle Island. This 22-acre urban park is connected to the mainland by both pedestrian and vehicular causeways. Pleasure Bay, the M Street Beach and Carson Beach form a three mile segment of parkland and beach along the South Boston shoreline of Dorchester Bay. Carson Beach offers some beautiful views and great public amenities: a rehabilitated Mothers' Rest, public restrooms, exhibit space, first aid and lifeguard functions, while the outdoor courtyards allow space for passive recreation. Carson Beach also features a walkway which allows one to walk, bike, or run along the water's edge from Castle Island to the Kennedy Library.

Fort Independence and Castle Island are on the State and National Registers of Historic Places. Fort Independence is open from Memorial Day to Columbus Day, hours vary. Fort tours are conducted by the Castle Island Association in the summer months and there is interpretive signage for self-guided tours. The principal program theme, the History of Castle Island, stresses the role of the fort in harbor defense.

Castle Island is South Boston’s island paradise with gorgeous ocean views in every direction. There is a child safe playground for the kids and a city sponsored sailing club for the teens. The anglers have a well constructed fishing pier to indulge in their favorite sport while kiters have open fields ,buffeted by the ocean breezes, to test flight their latest purchases. The runners and walkers have their own circular track extending from the islands shoreline and back,creating a mammoth ocean swimming pool for the publics summers use. Over looking it all is Fort Independence reminding us that this bounty was made possible because of the sacrifice of those brave men and woman whom we honor as our Patriots .

I love this park! This is my favorite place to run, especially in the summer when the breeze lowers the temps by 10 degrees.

Great place for a day picnic with the family. Carry a jacket with you, this place is always windy. Parking could be a problem, so be patient.

Wonderful, magical, and free The island is a fun place to swim, use the playground, fish, watch the planes land and take off or barbecue or grab some burgers and ice cream from Kelly's Restaurant. It is the home of Fort Independence.
