The Porcupine Islands are an archipelago of five islands that lie in the Mount Desert Narrows of Frenchman Bay in Bar Harbor, Maine, United States.
All of the islands, except for Burnt Porcupine, are maintained by the National Park Service through Acadia National Park (which is situated on the larger Mount Desert Island that the archipelago comes off).
[1] The islands also serve as nesting grounds for various sea birds, like bald eagles.
[1] The islands can be accessed through sea kayaking (or canoeing) or through local boat tours out to them.
The Porcupine Islands served as a hiding place for Frenchmen, during the French and Indian War, who were waiting to attack British ships that came through the area.
