Cadillac Mountain is located on Mount Desert Island, within Acadia National Park, in the U.S. state of Maine. With an elevation of 1,530 feet (466 meters), its summit is the highest point in Hancock County and the highest within 25 miles (40 km) of the Atlantic shoreline of the North American continent between the Cape Breton Highlands, Nova Scotia and peaks in Mexico. It is known as the first place in the U.S. to see the sunrise, although that is only true for a portion of the year.
