Denver, Colorado, often known as the Mile-High City, does  indeed includes one step on its capital building that is literally 5,280 feet above sea level. The rest of the city–with a few exceptions–is a little more or a little less than a mile high. This fact, combined with its beautiful Rocky Mountain setting, makes the highest capitol of the 50 United States a remarkable and beautiful example of urbanature at altitude, combining glorious scenic views with world-class skiing close by, and an occasional bald eagle visible in City Park downtown.
