You can come here to walk a Civil War-era fort, visit historic lighthouses, explore tide pools, hike lush trails, camp under the stars, or relax while fishing, picnicking or swimming—all within reach of downtown Boston. Youth programs, visitor services, research, wildlife management, and more are coordinated on the park's 34 islands and peninsulas by the Boston Harbor Islands Partnership.
