Boston Harbor Islands National Recreation Area

... where you can walk a Civil War-era fort, view 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.

About under an hour from Boston and 1 hours from Providence by car.
