The centerpiece of the Alaska Range, which at 20,320 feet above sea level, is the tallest mountain in the U.S. Add that to the many large glaciers and the abundant wildlife and you’ve got a great place to ride your snowmachine. Situated between the Talkeetna Mountains and the Alaska Range, Denali is halved by the Parks Highway. The eastern half of the park, which spans more than 325,000 acres, is dominated by the Curry and Kesugi Ridges, with snow accumulations in excess of six feet. You can ride snowmobile throughout the park when snow depth is sufficient—about 16 inches. But keep in mind that about 15% of the park is glaciers.
