"High Island" is the name given by Samuel Champlain during his explorations of the Maine coast in 1604. Although shell heaps along the island's shores tell of an American Indian presence long before Champlain's arrival, it wasn't until the end of the American Revolution that farmers, fishermen, and boat builders came to the island in large numbers. In the 1880s a small summer community was established, attracted by agreeable weather and idyllic scenery.
In 1943, heirs of the founder of that community donated portions of Isle au Haut to the federal government as part of Acadia National Park. Because of their generosity, much of the island's beauty is now yours to experience and enjoy.
Half of Isle au Haut is federal park land. The other half is privately owned, with summer residents and a year-round fishing community.

Isle au Haut is linked to the mainland by a year-round, passenger-only ferry from Stonington to the Isle au Haut Town Landing. From mid-June through late September, the ferry also stops at the Duck Harbor Boat Landing, near the campground. The ferry operates on a first-come, first-served basis.
