Imagine a place where you can explore tide pools, walk through a Civil War era fort, climb a lighthouse, hike lush trails, camp under the stars, or relax while fishing, picnicking, or swimming...all within reach of downtown Boston.

Ranger-led tours are available on many of the islands. Activities such as concerts, theater, children's activities and boat cruises are offered throughout the season. For a current list of events and programs, please follow the link below.
