Home to the lesser-known section of Acadia National Park, Isle Au Haut is also a thriving year-round community some seven miles off of Stonington.


Isle au Haut, French for “high island” and locally pronounced “i-la-HO,” lies in eastern Penobscot Bay, seven miles south of Deer Isle. Approximately six miles long and two miles wide, over half of Isle au Haut’s land mass is part of Acadia National Park. There is consider­able day-tripping traffic into the park, which offers 18 miles of hiking trails. A long-standing summer colony on the northern end of the island accounts for the bulk of the increase in summer population. The primary industry on the island is lobstering, although many house­holds also gain income through carpentry and caretaking.
