Great Cranberry is the largest island in the town of Cranberry Isles at just over 1,000 acres, but it has a smaller population than the village of Islesford on Little Cranberry Island. Approximately 40 year-round residents live on Great Cranberry Island, or “Cranberry,” predominantly working in various construction trades or at one of the island’s two boatyards that store, repair and build boats. Great Cranberry has a general store, post office, library, school, historical society, the Whale’s Rib Gift Shop, volunteer fire department building, Congregational Church and an extensive set of buildings owned and operated by the Cranberry Island Ladies’ Aid Society.
