Shackford Head State Park
Schackford Head State Park, near downtown Eastport, Maine and St. Andrews, New Brunswick, “encompasses 90 acres on Moose Island overlooking Cobscook Bay. This promontory at the entrance to Cobscook Bay encircles the west side of Broad Cove”. The park has “some wheelchair accessible trails (MaineTrailFinder) near the parking lot, but not all the trail network is accessible” and some trails are quite difficult. Fog and low visibility are common. Here is a website from VisitMaine and another from the Department of Agriculture. Phone 207-726-4412 Trail Map.
