Denali National Park comprises a massive area of six million acres, slightly more than the entire state of Massachusetts. The park is best known for the 20,320 foot Denali/Mt. McKinley (named after then-senator and future President William McKinley). The tremendous 18,000 foot difference from the mountain's lowlands near Wonder Lake up to its peak is a greater vertical relief than that of Mount Everest. The park is bisected from east to west by the Alaska Range and the Park Road is the only vehicle access into the park.The park was established in 1917 as a wildlife refuge. It was originally named Mount McKinley National Park, but in 1980 the park was renamed and expanded in size by four million acres as part of the Alaska National Interest Lands Conservation Act (ANILCA). Today the park is managed as three separate units: '''Denali Wilderness''' is made up of the original Mount McKinley National Park and is managed to retain the undeveloped wilderness with no hunting allowed. The '''Denali National Park''' management area includes some of the 1980 additions and allows subsistence hunting. '''Denali National Preserve''' includes two areas of the park within which sport and subsistence hunting are allowed on a permit basis. http://wikitravel.org/en/Denali National Park
