Denali National Park and Preserve is nearly 6 million acres and over 9,419 square miles in size. At the heart of Denali National Par is Mt. McKinley, the highest mountain in North America at 20, 320 feet. The surrounding peaks of the 600-mile long Alaska Range are no less impressive than McKinley itself, and provide the scenic backdrop to the pristine wilderness that makes Denali an important wildlife preserve. The park is famous for its rugged peaks, spectacular landscapes, and abundant wildlife.
