Boston Harbor Islands national park area includes 34 islands situated within the Greater Boston shoreline. The islands are rich in natural and cultural resources. Imagine a place where you can explore tide pools, walk through a Civil War era fort, climb a lighthouse, hike lush trails and salt marshes, camp under the stars, or relax while fishing, picnicking or swimming...all within reach of downtown Boston.

The 34 islands are managed by a unique, 13-member Partnership which includes the National Park Service and other public and private organizations. An advisory council provides a mechanism for public involvement.
