Castle Island

WHEN: Daily, year-round

Besides the historic fort known as The Castle, and together with Pleasure Bay, M Street Beach and Carson Beach, you’ll find three miles of recreational fun: Fishing, a scenic overlook, picnic areas, swimming, a boardwalk, and restaurants. The history of the various forts that have protected Boston’s harbor is as fascinating as the view.
