Acadia National Park is the U.S. national park centered on Mount Desert Island.
Located on the Maine coast, Acadia includes roughly half of Mount Desert Island as well as sections of Isle au Haut, the Schoodic Peninsula, and smaller islands. Its landscape combines granite mountains, glacially carved valleys, lakes, forests, rocky shorelines, and Cadillac Mountain, the highest point on the North Atlantic coast of the United States.
The park grew from private conservation efforts led by figures such as George B. Dorr and Charles W. Eliot. President Woodrow Wilson first protected the area as Sieur de Monts National Monument in 1916; it became Lafayette National Park in 1919 and received the name Acadia National Park in 1929. Mount Desert Island is not wholly parkland, so “centered on” does not mean the entire island lies inside the park.
