Cadillac Mountain is Acadia National Park's highest elevation and most comprehensive viewpoint. It is also the highest point on the United States Atlantic Coast at 1,500 feet. At dawn, a person standing there might be the first in the country to see the sun's first rays. The mountain is named for Antoine de la Mothe Cadillac, the Frenchman granted possession of the island in the late 1600s by King Louis XIV. Cadillac later founded Detroit, inspiring the name of the prestigious automobile. To the east are Frenchman Bay, its several islands, and Schoodic Peninsula beyond, while to the south lie Seal Harbor, the Cranberry Islands, and the open sea.
