Cranberry Isles

Great Cranberry and Islesford information for the Healthy Water, Healthy Aging project.

The Cranberry Isles are composed of Great Cranberry Island, Islesford, Sutton Island, Baker Island, and Bear Island. Only Great Cranberry Island and Islesford are year-round, and Baker Island is part of Acadia National Park, creating a unique mosaic of community types on the Cranberry Isles. The Cranberry Isles sport peatlands and cranberry shrubs, notable natural features and also their namesake. Now part of Hancock County, the Cranberry Isles are traditional territory of the Wabanaki people. About a quarter of residents participate in fishing or natural resource occupations, exemplifying the robust working waterfront in Maine. The Cranberry Isles also have a long history with the arts, being home to famous artists such as Ashley Bryan. The year-round population of the Cranberry Isles sits at around 140, growing during the summer season.
