The ragged, majestic peaks of the Brooks Range invite exploration and give way northward to rolling tundra, too far north for many trees to grow, where barren-ground caribou travel in huge herds and grizzly bears roam away their solitary lives. Moose, wolves, Dall sheep, black bears, and smaller mammals share the park. Eagles and hawks soar overhead. On the extreme northern verge the land is polar desert, one of the driest places on Earth. Remote glacier-carved valleys split the range, drained by clear rivers and dotted with alpine lakes.
Anglers head here for the grayling, char, and chum salmon often found in abundance in the rivers.
Although no established trails exist, backpacking is becoming increasingly popular in Gates of the Arctic. Many hikers carry a firearm for protection from bears, but attacks are uncommon. Climbers are attracted to the Arrigetch Peaks and Mount Igikpak. Sport hunting and trapping is allowed on the preserve section. Although camping is unrestricted, wood is scarce and campfires are discouraged.
