Islesford Historical Museum
Maritime heritage museum on Little Cranberry Island, accessible by seasonal boat tours from Northeast Harbor.
Natural Attraction
This museum on Little Cranberry Island preserves the maritime heritage and social evolution of a working fishing community transformed by seasonal wealth. Exhibits explore the schooner trade, commercial fishing economy, and the influx of summer residents who reshaped island life. The museum building itself represents vernacular island architecture and the isolation that defined Cranberry Isle existence. Accessible only by mail boat or narrated tour boat (late May through September; museum open mid-June through September), visitors experience the water-based dependence that shaped every aspect of island survival.
