Denali national park, Alaska
Dominated by Denali or Mount McKinley, this park hosts some of the Alaska range of mountains. While many of these mountains are some of the hardest to climb in the world the lower slopes have a wide variety of wildlife.
This is not limited to predators which include wolves, black bears, grizzly bears, coyote, Wolverine and Canada lynx, but include moose, caribou and dall sheep, among the large herbivores but there are many smaller ones.
The peaks can be inhospitable all year round, but the valleys you may find a very different environment.
