Acadia National Park on Maine’s mid-coast protects much of Mount Desert Island as well as parts of Isle au Haut, the Schoodic Peninsula, and smaller islands. Established through early twentieth-century conservation efforts, it was first federally protected in 1916, became Lafayette National Park in 1919, and took its current name in 1929. The first national park east of the Mississippi River and the only one in the Northeast, it is known for an unusually varied landscape of granite domes, beaches, lakes, forests, wetlands, and mountains, including Cadillac Mountain. The area also preserves a much older human story, from long Wabanaki stewardship to later French and British occupation.
