The Alatna, John, Kobuk, Noatak, and Tinayguk Rivers with the North Fork of the Koyukuk River make up six of the 13 National Wild and Scenic Rivers in Gates of the Arctic National Park. They have been byways for people and animals for thousands of years, and they support each summer's explosion of life. They're also navigable, with a variety of access points. Boating through the park reveals mountains, glacial valleys, and rolling tundra, plus glimpses of animals along the landscape.
Most people use rafts, inflatable canoes, packrafts, or other collapsible boats, as air taxis will not haul rigid vessels. Although the waters are generally Class I and II rapids, a few sections include Class II–IV rapids. The water is cold, and conditions constantly change, with levels fluctuating dramatically and the possibility of log jams and strainers. But when the going is good, boating can beat walking through thick tussocks and boggy ground. Many outfitters offer paddling options. If you're heading out on your own, talk to your air-taxi operator or local guides about current conditions.
