Gates of the Arctic National Park, in Alaska's central Brooks Mountain Range, is the source of dozens of wild rivers that are enjoyed by hikers and rafters each summer. Several Class I-II wild rivers, such as the North Fork of the Koyukuk, the Alatna, Killik, John, and Wild, offer a relaxing way to enjoy the Brooks wilderness. Many of the river outfitters plan short day hikes into the scenic mountains and side valleys.
      The Gates of the Arctic is a photographer's paradise. In addition to the primitive mountain wilderness scenery, Dall sheep, moose, grizzly bears, and wolves are frequently seen.
      The small village of Bettles, located just north of the Arctic Circle near the John and Wild rivers’ confluence with the Koyukuk River, is the outfitting and travel center for Central Brooks Range river expeditions.
