Isle au Haut thrusts its steeply ridged back out of the sea south of Stonington. French explorer Samuel D. Champlain discovered Isle au Haut—or "High Island"—in 1604, but heaps of shells suggest that native populations lived on or visited the island prior to his arrival. The island is accessible only by mail boat, but the 45-minute journey is well worth the effort. As you pass between the tiny islands of Merchants Row, you might see terns, guillemots, and harbor seals. The ferry makes two trips a day between Stonington and the Town Landing from Monday to Saturday, and adds a Sunday trip from mid-May to mid-September. From mid-June to mid-September, the ferry also stops at Duck Harbor, located within Acadia National Park. The ferry will not unload bicycles, kayaks, or canoes at Duck Harbor, however.
Except for a grocery store and a natural-foods store, Isle au Haut does not have any opportunities for shopping. The island is ideal for day-trippers intent on exploring its miles of trails, or those seeking a night or two of low-key accommodations and delicious homemade meals.
