Overview
Gates of the Arctic National Park and Preserve is the northernmost national park in the United States, lying entirely above the Arctic Circle in Alaska's Brooks Range. Established as a national monument in 1978 and redesignated a national park in 1980, it covers roughly 8.4 million acres, making it the second-largest national park in the country. It receives fewer visitors per year than almost any other unit in the National Park System, which is a direct reflection of its extreme remoteness and self-sufficiency demands.
The landscape spans boreal forest, open tundra, glacially carved valleys, and jagged mountain peaks. Six wild rivers — the Alatna, John, Kobuk, Noatak, North Fork of the Koyukuk, and Tinayguk — thread through the park and are popular routes for float trips. The park takes its name from two mountains, Frigid Crags and Boreal Mountain, which explorer Robert Marshall famously called the "gates" to the Arctic wilderness in the 1930s.
There are no roads, no maintained trails, no campgrounds, and no visitor facilities inside the park. This is not a place for casual visits. Every trip requires careful planning, strong wilderness skills, and respect for a landscape that does not offer rescue infrastructure.
Before You Go
Planning Essentials
Gates of the Arctic demands a level of self-sufficiency that exceeds virtually any other US national park. Before you go, contact the park's ranger stations — located in Coldfoot, Fairbanks, and Bettles — well in advance of your trip. Rangers can advise on current conditions, river levels, bear activity, and appropriate routes for your experience level.
All visitors must be fully equipped for rapidly changing Arctic weather, river crossings, and multi-day off-trail navigation. There are no maintained trails anywhere in the park, so strong map-and-compass or GPS navigation skills are essential. Topo maps should be studied thoroughly before arrival.
Key Preparation Points
- Bear safety: Carry a bear-resistant food container or approved bear canister; bear spray is strongly recommended. Grizzly bears are common throughout the park.
- Insects: Mosquitoes and biting insects can be extremely dense from late June through July. Head nets, insect-repellent clothing, and DEET-based repellent are not optional.
- Leave No Trace: The park has no waste facilities. Visitors must pack out all waste, including human waste in many river corridors. Check current regulations with rangers.
- Permits: As of the date of this guide, no backcountry permit is required, but registration with ranger stations is strongly encouraged. Verify current requirements on the official NPS site before your trip.
- Fishing: A valid Alaska fishing license is required for fishing within the park. Check Alaska Department of Fish and Game regulations for species-specific rules.
- Visas: If you are traveling from outside the United States, check the TravelerPulse Visas section and the official US Customs and Border Protection website for current entry requirements.
Getting There
Access Points
There is no road access into Gates of the Arctic. All access is by small aircraft (bush plane) or, for some areas, by foot from the Dalton Highway corridor along the park's eastern boundary.
By Air: The primary gateway towns served by scheduled small-plane service are Bettles (the most common jump-off point), Coldfoot, and Anaktuvuk Pass (the only community inside park boundaries). Air taxis operate from Fairbanks to these communities. From Fairbanks, commercial flights connect to Anchorage and major US hubs. Verify current air taxi operators and schedules locally or through the park's ranger stations, as small aviation operators change frequently.
Via the Dalton Highway: The Dalton Highway (Alaska Route 11) runs along the eastern edge of the park and preserve. Coldfoot, located on the Dalton Highway at mile 175, serves as a practical staging point for visitors arriving by vehicle. From roadside pull-offs near Wiseman and the Dalton Highway corridor, hikers can walk into the park on foot, though the terrain is demanding and distances to meaningful wilderness are considerable.
From Fairbanks: Fairbanks is the primary logistics hub for most visitors. It has a major airport (Fairbanks International, FAI), equipment rental options, resupply opportunities, and air taxi services. Plan to spend at least one night in Fairbanks for logistics before departing into the backcountry.
Getting Around
Movement inside Gates of the Arctic is entirely self-directed and off-trail. There are no roads, shuttle services, or maintained paths of any kind within the park.
On foot: Cross-country hiking through tundra, river valleys, and mountain terrain is the primary mode of travel for most visitors. River valleys generally offer easier walking than ridgelines, but wet tundra, tussocks, and unpredictable weather make progress slower than in lower-48 wilderness areas. Expect to cover fewer miles per day than you would on maintained trails elsewhere.
By packraft or raft: Float trips on the park's designated Wild and Scenic Rivers are a popular way to cover distance and access remote areas. Trips typically begin after a fly-in to an upstream location and end at a road or community. Experience with moving water and cold-water rescue techniques is essential. Packrafts have become increasingly common and allow hikers to combine walking and floating.
By bush plane: Charter flights can reposition parties within the park for an additional cost. This is often used for one-way traverse itineraries. Coordinate carefully with your air taxi operator well before departure, as weather can delay pickups by multiple days — build buffer days into your itinerary.
Where to Stay
There are no hotels, lodges, or developed campgrounds inside Gates of the Arctic. All overnight stays within the park are primitive wilderness camping. Visitors choose their own campsites on open public land; no reservation or permit system for camping currently exists inside the park, though this should be confirmed on the NPS website before your trip.
The gateway town of Bettles has very limited lodging and guide services — options change; verify locally. Coldfoot on the Dalton Highway has a small truck stop with limited lodging that serves as a staging area for some visitors. Fairbanks offers the widest range of hotels, hostels, gear shops, and services and is the recommended base for pre- and post-trip logistics.
Guided expeditions are available through a small number of licensed wilderness guide companies operating in the park. Using a reputable guide service is strongly recommended for first-time visitors unfamiliar with Arctic wilderness travel. A current list of authorized operators can be requested from the park's ranger stations or found on the official NPS website.
Things to See & Do
Wildlife Viewing
The Western Arctic Caribou Herd — one of the largest in the world — migrates through the park seasonally, and timing a trip to coincide with the migration (typically late summer and early fall for southward movement) can be spectacular. Grizzly bears, wolves, wolverines, Dall sheep, moose, and Arctic foxes are all present. Birdlife is rich during summer, including golden eagles, gyrfalcons, ptarmigan, and numerous shorebirds and waterfowl.
River Floating
The Noatak, Alatna, John, and North Fork of the Koyukuk rivers offer multi-day float trips ranging from beginner-friendly flatwater stretches to more technical canyon sections. Most trips require a fly-in to the put-in. Trip lengths range from a few days to several weeks depending on the river and take-out point. Check current river conditions with rangers before committing to a route.
Mountaineering and Hiking
The Brooks Range offers serious mountaineering objectives, particularly in the Arrigetch Peaks area, which is known for dramatic granite spires. Non-technical ridge walks and valley hikes are accessible to fit, experienced backpackers. The absence of trails means route-finding skills are mandatory.
Northern Lights
Winter visitors — typically arriving in March or April when temperatures, while extreme, are somewhat more manageable than midwinter — have excellent chances of viewing the aurora borealis. The park's total absence of light pollution makes aurora displays vivid on clear nights. Winter expeditions require specialized cold-weather gear and significant experience.
Anaktuvuk Pass
Anaktuvuk Pass is the only year-round community within the park, home to the Nunamiut people, an Iñupiat group. The Simon Paneak Memorial Museum here documents Nunamiut history and culture. Visitors should approach the community respectfully, recognizing it as a living village, not a tourist attraction. Call ahead and respect any community guidelines on visitor access.
Food & Drink
There are no restaurants, stores, or resupply points anywhere inside Gates of the Arctic. Every calorie you consume must be carried in with you or flown in as a resupply drop arranged with an air taxi operator before your trip.
Food planning is critical. Arctic conditions increase caloric demands significantly, and meals must be lightweight, calorie-dense, and resilient to temperature extremes. Freeze-dried backpacking meals, nuts, hard cheeses, jerky, and similar shelf-stable foods are standard. All food must be stored in bear-resistant containers at all times.
Water is generally abundant from rivers and streams but must be filtered or treated before drinking. Giardia and other pathogens can be present even in remote Arctic water sources. Carry a reliable filter or chemical treatment system. Coldfoot and Bettles have very limited food options; stock up fully in Fairbanks before departing.
Practical Information
Communication and Emergency Contact
There is no cell service inside the park. A satellite communicator (such as a SPOT device or Garmin inReach) is strongly recommended and considered by many experienced guides to be essential safety equipment. These devices allow two-way messaging and can send an SOS signal to rescue coordination centers. Verify that your device's subscription is active before departure.
For pre-trip information, contact the park ranger stations:
- Bettles Ranger Station — verify current contact information on the NPS website
- Coldfoot Ranger Station (Interagency Visitor Center) — open seasonally; verify hours
- Fairbanks Administrative Office — year-round; useful for planning
Medical and Emergency Services
There are no medical facilities inside the park. Evacuation by air is the only option in a medical emergency and can be delayed by weather for days. All party members should carry a comprehensive wilderness first aid kit, and at least one person should have wilderness first aid (WFA) or wilderness first responder (WFR) training. Evacuation costs are the visitor's responsibility; travel insurance that covers wilderness search and rescue and medical evacuation is strongly recommended.
Essential Gear Checklist (abbreviated)

Safety
Gates of the Arctic presents genuine risks that require honest assessment before you commit to a visit. The combination of no trails, no rangers on patrol, no cell service, extreme weather variability, cold river crossings, and abundant large predators creates a cumulative risk level that is uncommon even in other remote US wilderness areas.
River crossings are among the most dangerous hazards. Many routes require fording braided glacial rivers that can rise rapidly after rain. Never attempt a crossing without assessing current, depth, and downstream consequences. Use a pole or trekking poles for stability and unbuckle your pack hip belt before entering.
Weather in the Brooks Range can change from calm to dangerous — including snow — at any time of year. Hypothermia is a year-round risk. Carry gear rated for significantly colder and wetter conditions than a forecast might suggest.
Bear encounters: Grizzly bears are common throughout the park. Make noise while traveling, keep a clean camp, store all food and scented items in a bear canister at all times, and carry bear spray accessible — not buried in a pack. Know how to use it before you go.
Trip float plan: Always leave a detailed trip plan — including entry point, intended route, exit point, and expected return date — with a reliable contact outside the park who knows to alert Alaska State Troopers if you do not check in by a specified time.
Local Culture & Etiquette
The lands within and around Gates of the Arctic have been inhabited by Indigenous peoples for thousands of years. The Nunamiut (Iñupiat) people of Anaktuvuk Pass have lived in the central Brooks Range for generations, maintaining a culture centered historically on caribou hunting. The Koyukon Athabascan people inhabit areas to the south. Both groups maintain subsistence rights within the park that predate and supersede recreational use.
Visitors should approach any interaction with Indigenous communities with respect and cultural humility. Anaktuvuk Pass is a living community, not a historical exhibit. If visiting the Simon Paneak Memorial Museum, engage thoughtfully and follow any guidance from community members about photography or restricted areas.
The park's very existence reflects a sometimes-complex balance between wilderness preservation and the subsistence and cultural rights of Alaska Native peoples. Familiarizing yourself with this history before your trip enriches the experience and encourages more respectful engagement with the landscape and its people.
