Acadia National Park

Acadia National Park preserves much of Mount Desert Island, and associated smaller islands, off the Atlantic coast of Maine. The area includes mountains, an ocean shoreline, woodlands, and lakes. In addition to Mount Desert Island, the park comprises much of the Isle au Haut, a small island to the southwest of Mount Desert Island. A portion of Schoodic Peninsula on the mainland is also part of the park. In total, Acadia National Park consists of 30,300 acres (123 km²) on Mount Desert Island, 2,728 acres (11 km²) on Isle au Haut and 2,266 acres (9.2 km²) on the Schoodic Peninsula.

The park was created as Sieur de Monts National Monument on July 8, 1916, administered by the National Park Service. On February 26, 1919, it became a national park, with the name Lafayette National Park in honor of the Marquis de Lafayette, an influential French supporter of the American Revolution. The park's name was changed to Acadia National Park on January 19, 1929.

The town of Bar Harbor is located on the northeast corner of the island. Cadillac Mountain on the eastern side of the island is a famous tourist destination because it is one of the first places in the United States to see the sunrise. Miles of scenic carriage roads were originally built by John D. Rockefeller, Jr. with great sensitivity to the trees and contours of the land.
