[1] As a visitor attraction, Grape Island offers trails, rocky beaches, and camping in wooded campsites.

At weekends and summer weekdays it is served by a shuttle boat to and from Georges Island, connecting there with ferries to Boston and Quincy.

On the eve of the American Revolution, the island was owned by Hingham resident Elisha Leavitt, a Tory.

The island has an abundance of berries, including blackberry, dewberry, raspberry, blueberry, huckleberry, and American elderberry.

The island's marshy lowland contains salt tolerant species such as saltspray rose, cordgrass, purple loosestrife, honeysuckle, and seaside goldenrod.
