An oft-overlooked part of Acadia is Isle au Haut, a small island southeast of Mount Desert Island. Head there and you'll find the Duck Harbor Campground with its five rustic lean-to sites. Remote and inaccessible to automobiles, you'll need to land a reservation for these sites ($20, available mid-May through early October) through recreation.gov.
