Denali National Park and Preserve is a national park and preserve located in Interior Alaska, centered on Denali or Mt McKinley, the highest mountain in North America. The park and contiguous preserve encompass 6,045,153 acres which is larger than the state of New Hampshire. On December 2, 1980, 2,146,580-acre (3,354 sq mi) Denali Wilderness was established within the park. Denali’s landscape is a mix of forest at the lowest elevations with tundra at middle elevations, and glaciers, snow, and bare rock at the highest elevations. The longest glacier is the Kahiltna Glacier. To preserve the wilderness you can not drive past the visitor center but must board buses to reach the inner reaches of the park. Being a protected area animal sightings are very common with bear, caribou and moose the highlight. Be warned Denali is shrouded in clouds most of the time and it is difficult to get an unobstructed photo.
