Gates of the Arctic National Park

Log in to track your visit to Gates of the Arctic National Park.

Gates of the Arctic National Park and Preserve is the second largest national park in the United States at 8.5 million acres, and the most remote. Located entirely above the Arctic Circle in Alaska's Brooks Range, it is one of the few places left on Earth where a person can stand in genuine wilderness — no roads reach the park's boundary, no trails exist within it, no visitor center operates inside, and no facilities of any kind have been built in its vast interior. The park takes its name from two peaks — Frigid Crags and Boreal Mountain — that explorer Robert Marshall called the "gates" of the Arctic on his pioneering explorations in the 1930s. Marshall's writings about the Brooks Range helped inspire the modern wilderness preservation movement, and Gates of the Arctic stands as the ultimate expression of that vision: a place set aside not for ease of visitation but for the preservation of a complete, functioning Arctic ecosystem at continental scale. The Brooks Range here is not the dramatic, glacier-carved scenery of Denali or the Wrangells — it is a subtler, more intimate landscape of rounded peaks, braided rivers, tundra valleys ablaze with wildflowers in summer, and a silence so profound it becomes physical. The annual migration of the western Arctic caribou herd — once numbering nearly a million animals, now reduced but still one of the greatest wildlife spectacles on the continent — crosses the park's northern flank each year. This is a park for those who understand what wilderness truly means.

There are no trails, no trailheads, and no visitor infrastructure inside Gates of the Arctic. All travel is self-directed, cross-country, and demanding. The primary access is by small bush plane from Bettles, Coldfoot (both with ranger stations and visitor contact), or Fairbanks — charter flights land on gravel bars and lake shores throughout the park. River floating is the most popular extended activity: the North Fork of the Koyukuk, the Alatna, the Tinayguk, and the Noatak rivers all offer multi-day float trips through spectacular alpine and tundra valleys. Packrafting — a style of travel combining hiking and inflatable pack-raft paddling — is increasingly popular for exploring the park's interior. Backpacking trips require careful route-finding, bear canisters, and thorough wilderness experience. Visitors who fly in for a day can hike the tundra, fish for Arctic grayling and lake trout, and simply sit with the landscape. The ranger station at Bettles (just outside the park) is the essential first stop for planning and required permits.

The western Arctic caribou herd migrates through and around the park twice yearly — the spring northward migration and the fall southward return — with animals sometimes numbering in the hundreds of thousands crossing river valleys in waves. Grizzly bears are abundant throughout the Brooks Range and are a constant companion (and safety consideration) for backcountry travelers. Gray wolves follow the caribou herds and are more commonly seen here than almost anywhere else in Alaska. Dall sheep navigate the high ridges. Muskox have been reintroduced to the adjacent area. Golden eagles breed in cliff faces across the range. Arctic grayling inhabit nearly every river and stream.

There is no entrance fee for Gates of the Arctic. Planning must begin months in advance. The NPS visitor contact stations in Bettles (late May–early September) and Coldfoot (year-round, staffed seasonally) are essential resources — rangers provide mandatory bear canister loans, current conditions, and route advice. All visitors must practice Leave No Trace to an extreme degree; human waste must be packed out or buried according to NPS guidelines. Trip planning resources are available at nps.gov/gaar. Travel is feasible late June through early September; earlier and later months bring unpredictable weather and deeply cold conditions.

No road reaches Gates of the Arctic National Park. The two main access points are Bettles, AK (accessible by small plane from Fairbanks, 170 miles south) and Coldfoot, AK (on the Dalton Highway/AK-11, 250 miles north of Fairbanks). Fairbanks International Airport (FAI) is the primary hub. From Fairbanks, you can drive the Dalton Highway north to Coldfoot and Wiseman, communities near the park's eastern boundary — the drive alone is a remarkable Arctic adventure. Charter flights into the park interior are arranged through Bettles-based air taxis.

This park is not for beginners — it demands advanced wilderness navigation, bear safety knowledge, river crossing ability, and complete self-sufficiency. Talk to a ranger before any trip. Bear canisters are required throughout the park. Weather in the Brooks Range is notoriously unpredictable; build extra days into any itinerary for weather delays that ground aircraft. Mosquitoes in July are legendarily intense — bring a head net, DEET, and treat clothing with permethrin. The midnight sun in June and July means 24-hour daylight; bring a sleep mask if you need darkness to rest. This is one of the planet's last true wild places: approach it with appropriate humility.
