Denali National Park and Preserve, just over 6 million acres, is one of the largest national parks in the United States. The park includes North America's highest mountain, 20,320-foot tall Mount McKinley, a designated wilderness area and is an international biosphere reserve.
Denali is one of over 400 National Park Service units that, working with other partners, helps safeguard this nation's natural and cultural heritage.
