Acadia National Park Isle au Haut

Acadia National Park "High Island" is the English translation for Isle au Haut, the name given by the great French navigator Samuel Chaplain 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 Chaplain'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, attracted by agreeable weather and idyllic scenery, was established. 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 and solitude is now yours to experience and enjoy. Although about one-half of Isle au Haut is federal park land, the other half is privately owned, with summer residents and a year-round fishing community. Please respect private property rights.


Eighteen miles of trails offer opportunities to explore rocky shoreline, wooded uplands, marshes, bogs, and a mile-long freshwater lake. Be prepared for rough and sometimes wet trails. Bring adequate footgear, warm clothing, and raingear. Duck Harbor provides the best starting point for hiking. During the summer, a park ranger may board the ferry at the town landing to answer questions about Isle au Haut. Upon arrival to Duck Harbor, you may elect to hike with the ranger or explore on your own.


Bicycles are prohibited on hiking trails. There are only five miles of paved roads and seven miles of rough, unpaved roads. The ferry charges an additional fee to transport bicycles and will only drop them off and pick them up at the town landing.
