Located North of the Arctic Circle in an area larger than Switzerland, the Gates of the Arctic National Park and Preserve can seem forbidding at first, but the land has actually been home to humans for over 11,000 years. The terrain ranges from mountain, to tundra, to rivers and canyons. Here it is possible to climb the Brooks Range or white water raft six rugged rivers, sharing the land with 36 species of wild mammals, including two types of bears, moose, caribou and wolves.
