Wilderness and Biosphere Reserve

Denali National Park & Preserve features North America's highest mountain, 20,320-foot tall Mount McKinley. The Alaska Range also includes countless other spectacular mountains and many large glaciers. Denali's more than 6 million acres also encompass a complete sub-arctic eco-system with large mammals such as grizzly bears, wolves, Dall sheep, and moose.

The park was established as Mount McKinley National Park on Feb. 26, 1917. The original park was designated a wilderness area and incorporated into Denali National Park and Preserve in 1980. The Park was designated an international biosphere reserve in 1976.

Today the park accommodates a wide variety of visitor use including wildlife viewing, mountaineering, and backpacking. It continues to provide a laboratory for research in the natural sciences.
