Which U.S. national park lies entirely north of the Arctic Circle?

Gates of the Arctic National Park and Preserve is the U.S. national park located entirely north of the Arctic Circle. It protects a vast portion of Alaska’s Brooks Range, including glacier-carved valleys, alpine lakes and tundra.

The area became Gates of the Arctic National Monument in 1978 after President Jimmy Carter used the Antiquities Act. Congress redesignated it as a national park and preserve in 1980 through the Alaska National Interest Lands Conservation Act.

Unlike many national parks, Gates of the Arctic has no roads, official trails or campgrounds. Visitors generally arrive by bush plane or travel overland through remote wilderness. The name came from wilderness advocate Bob Marshall, who described two mountains flanking the North Fork of the Koyukuk River as the “Gates of the Arctic.”
