Gates of the Arctic National Park Guide: Best Hikes, When to Visit & Where to Stay

Gates of the Arctic National Park and Preserve encompasses 8.4 million acres of pristine wilderness entirely north of the Arctic Circle in Alaska's Brooks Range. There are no roads, no trails, no bridges, no campgrounds, no visitor facilities within the park, and no cell service. It is the least visited national park in the United States outside of the remote Pacific island parks, receiving fewer than 10,000 visitors in most years. This is wilderness in its most absolute form.

The park takes its name from two peaks, Frigid Crags and Boreal Mountain, which flank the North Fork of the Koyukuk River like pillars of a gate. The explorer Robert Marshall coined the name in the 1930s while exploring the central Brooks Range on foot, and his vision of preserving this landscape led ultimately to its designation as a national park in 1980. The Brooks Range extends east to west across northern Alaska, a rugged barrier of jagged peaks, U-shaped glacial valleys, and vast expanses of arctic tundra. North of the divide, rivers flow to the Arctic Ocean. South of it, they drain into the Yukon.

The park is home to caribou of the Western Arctic Herd, one of the largest caribou herds in the world. Grizzly bears, wolves, wolverines, Dall sheep, moose, and muskoxen all inhabit the park. The tundra landscape supports a surprisingly diverse community of arctic plants, from dwarf willows and blueberries to mosses and lichens that paint the hillsides in subtle greens, reds, and golds during the brief summer. The Nunamiut Eskimo people have lived and hunted in the Brooks Range for thousands of years, and the village of Anaktuvuk Pass, located within park boundaries, remains an active Nunamiut community.

Best Hikes

Arrigetch Peaks - The Arrigetch Peaks are a cluster of dramatic granite spires rising above the tundra in the heart of the Brooks Range, their name meaning "fingers of the outstretched hand" in the Nunamiut language. Access is typically by bush plane to a gravel bar on Arrigetch Creek, followed by an 8-mile cross-country trek up the creek valley to the base of the peaks. There are no trails. Hikers navigate along creek beds, through willow thickets, and across tundra benches. The cirques at the base of the peaks are among the most spectacular alpine scenery in North America. Most parties spend five to seven days in the area.

North Fork Koyukuk River - The classic Gates of the Arctic route follows the North Fork of the Koyukuk River through the valley between Frigid Crags and Boreal Mountain, the original "gates." Bush plane access to gravel bars along the river allows for multi-day backpacking trips through broad glacial valleys with excellent wildlife viewing. The terrain is open tundra and river bars, making cross-country travel relatively straightforward. Caribou, grizzly bears, and wolves are frequently observed.

Alatna River Valley - The Alatna River rises in the heart of the Brooks Range and flows south through a series of increasingly broad valleys to the Koyukuk River. Float trips of 80 to 100 miles are popular, combining packrafting or canoeing with side hikes into tributary valleys. The upper Alatna passes through dramatic mountain scenery, while the lower stretches wind through boreal forest. Bush plane drop-off on a mountain lake and pickup on a downstream gravel bar is the standard logistics pattern.

Mount Igikpak - At 8,510 feet, Mount Igikpak is the highest peak in the western Brooks Range and a challenging objective for experienced mountaineers. The approach involves a bush plane flight to a nearby lake or gravel bar, followed by several days of cross-country travel to the base. The peak itself requires glacier travel and technical climbing skills. Views from the summit encompass hundreds of miles of unbroken wilderness.

Noatak River Headwaters - The Noatak River originates in the park and flows west for 400 miles to the Chukchi Sea, making it one of the longest undammed rivers in the United States. Backpacking trips in the upper Noatak valley near its headwaters offer expansive tundra hiking with views of the Schwatka Mountains. Caribou migration routes cross this area, and large herds may be encountered in late summer.

Walker Lake - One of the more accessible destinations in the park, Walker Lake is a large, deep lake at the southern edge of the Brooks Range accessible by bush plane from Bettles. Day hikes and multi-day trips radiate from the lakeshore into the surrounding mountains. The lake supports excellent lake trout and grayling fishing. The surrounding forest and tundra transition zone provides good wildlife habitat.

When to Visit

Late June to Early July (Early Summer) - The snow has melted at lower elevations, rivers are running high with snowmelt, and the tundra is beginning to green up. Days are essentially continuous, with 24 hours of sunlight north of the Arctic Circle around the summer solstice. Mosquitoes emerge in staggering numbers by late June and remain intense through July. Temperatures range from 40 to 70 degrees at lower elevations. River crossings can be challenging due to high water.

Mid-July to Early August (Peak Summer) - The optimal window for most visitors. The tundra is in full bloom, rivers have dropped to more manageable levels, and wildlife is active. Grizzly bears are visible on hillsides digging for roots and ground squirrels. Dall sheep occupy high ridges. The Western Arctic Caribou Herd begins its southward migration in late July and August, potentially bringing thousands of animals through the park. Mosquitoes remain present but somewhat diminished.

Late August to Mid-September (Autumn) - Fall color sweeps across the tundra in late August and early September, turning the landscape into a tapestry of red, orange, gold, and green. The mosquitoes are gone. The air is crisp, and the first frosts dust the tundra at night. Blueberries carpet the hillsides. By mid-September, snow may begin accumulating at higher elevations, and daylight diminishes rapidly. This is widely considered the most beautiful time to visit the Brooks Range.

October to May (Winter) - Extreme cold, deep snow, and limited daylight make winter travel in the park a serious undertaking attempted by very few. Temperatures can plunge below minus 50 degrees. The northern lights are visible from September through March. A few experienced winter travelers visit on skis or snowshoes, but logistical support is minimal.

Where to Stay

Bettles Lodge - Located in the small community of Bettles, the primary staging point for trips into the park, this lodge offers rooms, meals, and logistical support for backcountry travelers. The lodge can arrange bush plane charters, provide trip planning advice, and sell fuel and limited supplies. Bettles has a year-round population of roughly a dozen people.

Coldfoot Camp - Located along the Dalton Highway at Coldfoot, approximately 75 miles east of Bettles, this truck stop and camp offers basic motel rooms, a restaurant, fuel, and a post office. Coldfoot serves as an alternative staging point for trips into the eastern portions of the park and is accessible by road from Fairbanks.

Backcountry Camping - There are no developed campgrounds in the park. All camping is dispersed backcountry camping. Visitors select their own sites, typically on gravel bars, tundra benches, or alpine ridges. Leave No Trace principles are mandatory. Bear-resistant food containers are strongly recommended, and cooking should be done at least 100 yards from sleeping areas.

Anaktuvuk Pass - This Nunamiut village within the park boundaries has a small lodge and cultural museum. Visitors can fly in from Fairbanks or Bettles and use the village as a staging point for trips into the surrounding mountains. Respect for the community and its residents is essential.

Getting There

By Bush Plane from Bettles - Most visitors fly commercially from Fairbanks to Bettles on scheduled flights operated by Ravn Alaska or Wright Air Service, then charter a bush plane from Bettles into the park. Bush pilots will land on gravel bars, tundra strips, and lakes throughout the park. Trips must be planned with the bush plane operator in advance, including both drop-off and pickup locations and dates. Weather delays are common and should be built into every itinerary.

By Air from Fairbanks - Fairbanks International Airport (FAI) is the primary gateway, receiving flights from Anchorage, Seattle, and other cities. From Fairbanks, scheduled air service to Bettles takes approximately one hour. Charter flights directly into the park from Fairbanks are also possible but more expensive.

Via the Dalton Highway - The only road access near the park is the Dalton Highway, which parallels the eastern boundary. No roads enter the park, but hikers can walk into the park from several points along the highway. The most popular walk-in access point is near Wiseman, a small community at mile 188 of the Dalton Highway. From Fairbanks, the drive to Wiseman takes approximately six hours on the partially paved, partially gravel Dalton Highway.

Essential Tips

• This is the most remote national park in the country. There are no trails, no facilities, no rangers to assist you in the backcountry, and no cell service. You are entirely self-sufficient from the moment your bush plane departs until it returns. Carry a satellite communication device (InReach, SPOT, or satellite phone) for emergencies.
• Bear awareness is critical. Grizzly bears are common throughout the park. Carry bear spray and know how to use it. Store all food in bear-resistant containers. Make noise while traveling to avoid surprising bears. Cook and eat at least 100 yards from your tent.
• River crossings are a major hazard. Brooks Range rivers are cold, swift, and often silty. Use trekking poles, unbuckle your pack's hip belt before crossing, link arms with partners in deeper water, and choose crossing points carefully. Some rivers cannot be safely crossed during high water.
• Hypothermia is possible in any season. Summer weather in the Brooks Range can include freezing rain, sleet, and snow at any time. Pack warm layers, rain gear, and a shelter you can deploy quickly.
• No permits or fees are required to enter the park, but you should register at the Bettles Ranger Station or Coldfoot Visitor Center before departing into the backcountry. Rangers can provide current conditions, route advice, and bear activity reports.
• Mosquitoes are legendary. From late June through mid-August, the mosquito populations in the Arctic are among the densest on Earth. A head net is not optional, it is essential survival equipment. Bring DEET, permethrin-treated clothing, and long sleeves.

Nearby Attractions

Arctic National Wildlife Refuge - East of the park, the Arctic Refuge protects 19.3 million acres of wilderness including the calving grounds of the Porcupine Caribou Herd on the Arctic Coastal Plain. Access is by bush plane, and the refuge offers even more remote wilderness experiences than the park.

Dalton Highway - This 414-mile gravel and paved highway runs from Fairbanks to Deadhorse on the Arctic Ocean, paralleling the Trans-Alaska Pipeline. The drive is an adventure in itself, crossing the Yukon River, the Arctic Circle, and Atigun Pass in the Brooks Range. Services are extremely limited along the route.

Yukon Flats National Wildlife Refuge - South of the Brooks Range, this refuge protects one of the largest and most productive wetland basins in North America. Millions of waterfowl nest here each summer, and the refuge is significant habitat for salmon, moose, and bears.

Fairbanks - Alaska's second-largest city offers the University of Alaska Museum of the North, Chena Hot Springs, gold mining history at Gold Dredge 8, and the Large Animal Research Station where muskoxen and caribou can be viewed. Fairbanks is also one of the best places on Earth to view the northern lights.
