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.[2]
The island was farmed and grazed for three hundred years, until the 1940s. On the eve of the American Revolution, the island was owned by Hingham resident Elisha Leavitt, a Tory.[3] In 1775, British troops raided the island during the siege of Boston, as Abigail Adams wrote to her husband John about May 24, 1775: "...it seems their Expidition (sic) was to Grape Island for Levets hay."[3] A pitched battle ensued until the British were forced to retreat to the mainland. The angry colonists burned Leavitt's barn to the ground.[4] In the end, very little damage was done to either side despite the effort expended. Three British soldiers may have been wounded (unconfirmed), no Continental soldiers or partisans were wounded, and less than two tons of hay were taken by the British.[5]
Grape Island contains two freshwater springs. One spring is located on the north side of the western drumlin and is located underneath a large boulder that faces Peddock's Island. Another freshwater spring is located behind the marsh that is situated in the saddle between the two drumlins. Both of these areas are off the trail.
