On the trail, when a brown shape moves at the edge of the willows, the question of safety stops being abstract. Alaska asks little of visitors beyond good habits: keep your distance from wildlife, dress for cold and wet, hike with someone, and know that a hospital can be far away.
What health issues should visitors know?
The main health risks in Alaska come from the outdoors: cold and wet weather, falls, and encounters with wildlife. Most of the official guidance below comes from the National Park Service in Denali and from the Alaska Department of Fish and Game, and it reads as a set of habits more than a list of dangers.
Cold, wet weather and hypothermia
In Denali, the Park Service says hypothermia is always a factor in the subarctic. That is true even when a morning starts out pleasant. Snow can fall nearly any month of the year there, so a bright day does not mean the weather will hold.
The answer is layers, preferably wool or synthetic material, plus rain gear or an umbrella. Layers let you add or shed warmth as clouds move in, and fabrics that keep insulating when damp matter more than a single heavy coat. Think of it as dressing for a changeable day rather than for a forecast.
Falls and hiking habits
One fact in the Denali guidance deserves attention: more people die from falls than any other cause in the park. Slippery rock, loose slopes and wet ground are the usual setting, and a moment of distraction while looking at a view can be enough.
The Park Service asks visitors to always hike with at least one other person and to make sure someone else knows where they are going. If something goes wrong, a companion can help, and a person waiting at the other end knows when to worry. Keep your eyes on the footing, and stop walking when you want to look around.
Bears and other wildlife
All three North American bear species, black bears, brown bears (including grizzlies) and polar bears, flourish in Alaska, according to the Alaska Department of Fish and Game. Anyone in the state is expected to keep all human sources of food secure from bears. That covers camp meals, coolers, trash and anything else with a scent.
In Denali, visitors must stay 300 yards from bears and 25 yards from other animals at all times. Feeding or harassing wildlife is not allowed: the park’s phrase is to keep wildlife wild. Bear spray is strongly encouraged for all hikers there.
If a situation with a bear turns dangerous, it should be reported to ADF&G through its wildlife encounter form. The agency also offers a page on bear resistant containers, and the U.S. Fish and Wildlife Service publishes safety guidelines for polar bear country.
Plants and the little things
Denali has no poison oak, sumac or ivy. Some other plants can still cause allergic reactions, cow parsnip among them, so it is wise to avoid brushing bare skin against unfamiliar tall greenery along a trail.
Tides are a different kind of hazard on the coast. In Glacier Bay, up to 24 feet of water flows in or out every six hours, and the Park Service calls the mixing of tides a major force and an ecosystem in itself. It is a reminder that shorelines there are working landscapes, not static scenery.
How far is medical care?
Medical care can be a long way off once you leave the cities: even the entrance of Denali is several hours from the nearest hospital. That one fact shapes how you plan a day outdoors in the park, because small problems need to stay small.
Reaching help in Denali
In Denali National Park, dial 9-1-1 in an emergency and be ready to give your location as Denali National Park. Cell phone coverage exists only within three miles of the park entrance, so beyond that you cannot count on a signal to call anyone at all.
That is one more reason the Park Service wants you hiking with a partner and leaving word of your route. For questions that are not emergencies, a ranger answers the phone at 907 683-9532 from 9 am to 4 pm daily, except on major holidays.

The Alaska Native Medical Center in Anchorage
Anchorage is home to the Alaska Native Medical Center, a non-profit health center that provides medical services to 158,000 Alaska Natives and other Native Americans in Alaska. The current facility opened in May 1997 and is a 380,635 square foot building with 167 beds.
It anchors a wider network. The center belongs to the Alaska Federal Health Care Access Network, which provides telehealth services to 180 Alaska Native community village clinics. That tells you something about the state: care often travels by screen to places that people cannot easily reach by road.
A 202-bed patient housing facility, connected to the hospital by skybridge, opened on January 2, 2017. Ronald McDonald House occupies its sixth floor for families and expectant mothers with high risk pregnancies. Quyana Hospitality Services is a complimentary service for patients, helping with Medicaid extensions, housing upon provider referral, and patient travel within the Anchorage service area or after a medevac to the center.
Park mailing addresses
For written questions to the big parks, Wrangell-St. Elias National Park & Preserve lists PO Box 439, Mile 106.8 Richardson Highway, Copper Center, AK 99573. Glacier Bay National Park & Preserve lists PO Box 140, Gustavus, AK 99826. These are mailing addresses, useful for correspondence rather than for emergencies.
What should you carry?
Carry layers, rain protection, bear spray and a plan someone else knows about. Everything the official guidance asks for fits in a daypack, and none of it is exotic.
Clothing for a changeable day
Denali’s guidance is to dress in layers made of wool or synthetic material and to bring rain gear or an umbrella. Because snow can fall nearly any month of the year there, a warm layer belongs in the pack even on a day that starts mild.
A base layer that holds warmth when damp, a middle layer, and a waterproof shell cover most situations. Putting the shell on early, before you are soaked, is the habit that keeps hypothermia away.
Bear spray and food storage
Bear spray is strongly encouraged for all hikers in Denali, so it belongs on your list. Pair it with the rule that applies across Alaska: keep all human sources of food secure from bears. At a campsite or a cabin, that means putting food away rather than leaving it out, and ADF&G has a page on bear resistant containers for exactly that purpose.
If you want to learn before you go, ADF&G lends four bear safety videos and DVDs from its Area Offices in Anchorage, Fairbanks and Juneau. A 19-minute DVD called HEY BEARS!!!
How YOU Can Stay Safe in Bear Country is free for classrooms or youth groups. The Anchorage Bears Story Map shows data from a project that tracked nine bears with GPS collars carrying video cameras, a good look at how close bears live to a city.
A plan, a partner and a phone
The most useful things you carry are not in the pack. Bring a hiking partner, and tell someone where you are going. Take a phone for the area near the entrance, where coverage exists within three miles, but do not rely on it beyond that.
Keep a camera lens in mind too. The 300 yards from bears and 25 yards from other animals in Denali is a distance you keep at all times, so a zoom lens or binoculars lets you watch without crowding anything.
Good to know before you go
Most of Alaska’s safety comes down to a few habits: stay far from animals, never feed them, dress for cold and rain, and leave word of your route. Park conditions pages are updated from time to time, and the ones for Wrangell-St. Elias and Glacier Bay carry their own dates, so the rangers’ phone line and the park addresses above are the places to go for the latest word on a specific area.
