Close to downtown Eastport, the easternmost city in the United States, Shackford Head State Park encompasses 90 acres on Moose Island overlooking Cobscook Bay. This promontory at the entrance to Cobscook Bay encircles the west side of Broad Cove. Several miles of trails cross the headland. A hiking trail from the parking area leads through woods to a rocky headland 173 feet above sea level, passing several pocket beaches and protected coves.
