Why should I go?
Sullivan’s on Castle Island has been a South Boston staple since it opened in 1951. Founded by Dan Sullivan, Sr., it started with the goal of providing quality food at reasonable prices to Castle Island visitors. Over 70 years later, Sullivan’s remains committed to this philosophy and has become a summertime essential for locals and tourists alike.
The seafood shack offers an array of New England classics, such as lobster rolls, clam chowder, and fried scallops, in addition to burgers, hot dogs, chicken fingers, and fries. For drinks, be sure to try the raspberry lime rickey—a fizzy and refreshing local favorite.
Usually closed for the months of December, January, and February, Sullivan’s is a seasonal business signaling the coming of spring. Sullivan’s recently opened locations at Hub Hall in North Station and Hanover Crossing in Hanover, which stay open throughout the winter.
Castle Island (which is not actually an island, but a peninsula jutting out into Boston Harbor) is also home to Fort Independence, one of the nation’s oldest continually fortified sites of British origin in the United States. Visitors can join free tours of the granite bastion fort or stroll along the walking paths that overlook Pleasure Bay and Boston Harbor.
Castle Island also features views of the Boston skyline, airplanes taking off at Logan Airport, sailboats in the harbor, and fishermen casting off the nearby pier. A playground and grassy area make Castle Island popular with families with young children and pets.
