At 20,320 feet, Mount McKinley (Denali) is the tallest mountain in the North America. Typically, the higher the summit, the better the views, but most people can only imagine the stunning scenery from the top of McKinley. Situated in the Alaska Range in Denali National Park, climbing the mountain is extremely difficult and only the world's top mountaineers attempt the climb. Though significantly shorter than Mt. Everest, the world's highest peak, McKinley is the largest above sea level--the base to peak height rises more than 18,000 feet.
