Alaska is America's final frontier — a vast wilderness state where glaciers calve into fjords, brown bears fish alongside bald eagles, and the aurora borealis paints the night sky in emerald and violet. The largest US state by area covers 1.7 million square kilometres yet holds fewer than 750,000 people, making it one of the least densely populated places on Earth. From Anchorage's urban sophistication to Denali's soaring summit, from the Inside Passage's towering rainforests to the Arctic's endless tundra, Alaska offers unmatched natural grandeur.
Alaska is a generally safe destination for well-prepared travelers. Crime in tourist areas is low. The primary risks are environmental: wildlife encounters (bears, moose, wolves), extreme weather conditions, remote wilderness with limited emergency services, and rapidly changing mountain weather. Every visitor should carry bear spray in bear country, dress for cold weather year-round, and file trip plans for backcountry excursions.
Current safety advisory
Safe With Nature Precautions
No travel advisory for Alaska. US CDC has no health advisory. Travelers should be aware of wilderness hazards including wildlife, extreme cold, and geographic isolation. Emergency services in remote areas can take hours or days to arrive.

Essential safety tips
Practical advice that applies everywhere.
Carry bear spray at all times in any backcountry or park area — Alaska has approximately 60,000 brown/grizzly bears and 100,000 black bears. Bear spray (available at REI Anchorage, 1000 W Northern Lights Blvd, $50-60) is more effective than firearms in most bear encounters. Spray when the bear is within 60 feet; aim at the face in a 30-60 degree arc.
File a trip plan before any backcountry excursion — Leave a written trip plan with the Alaska State Troopers (907-269-5511) or a trusted contact listing your route, expected return time, and vehicle description. In remote areas, emergency response takes 12-72 hours. Carry a satellite communicator (Garmin inReach Mini, ~$400 purchase or $35/month subscription) as a backup to non-existent cell service.
Dress in waterproof layers regardless of the season — Alaska weather changes rapidly at any time of year. Interior temperatures in January can drop to -60°F (-51°C). Even in July, mountain and coastal areas can experience near-freezing temperatures and driving rain. Wear a moisture-wicking base layer, insulating mid-layer, and waterproof outer shell. Hypothermia is a genuine risk even in summer if unprepared.
Never enter or cross glacial streams alone or without proper assessment — Alaska's glacial rivers run extremely cold (32-38°F / 0-3°C) and fast, with invisible braided channels and shifting glacial gravel. Cold water immersion survival time is under 15 minutes. If crossing is necessary, use a trekking pole, face upstream, unbuckle pack straps, and cross at the widest and shallowest point — never the most obvious path.
Check and monitor aurora and avalanche forecasts for your region — The Alaska Avalanche Center (alaskasnow.org) provides daily regional forecasts for backcountry travelers. The Geophysical Institute aurora forecast (gi.alaska.edu/aurora-forecast) is updated daily and gives a 1-9 activity scale. For aurora viewing, Kp 3+ is visible with a dark sky; Kp 5+ is visible from Anchorage suburbs. Avalanche danger is real in the Chugach and Alaska Range from October through May.
Purchase travel insurance that includes emergency medical evacuation — A wilderness rescue in Alaska can cost $5,000-50,000+ depending on location and conditions. Medevac helicopter flights from remote areas run $5,000-20,000. Standard health insurance rarely covers wilderness rescue. Travel insurance with evacuation coverage (World Nomads, Allianz) or a dedicated wilderness rescue membership (Alaska Mountain Rescue Group) is strongly recommended for any backcountry activity.

Health considerations
Staying healthy on your trip.
- Items
- Concern
- Giardia
- Risk
- Medium
- Details
- Giardia lamblia is present in all surface water across Alaska. Never drink untreated water from streams, lakes, or rivers.
- Prevention
- Carry a water filter (MSR Trail Lite, Sawyer Squeeze) or iodine tablets. Boiling water for 1 minute also treats Giardia.
- Concern
- Mosquitoes
- Risk
- High (Interior, June-August)
- Details
- Alaska has approximately 35 species of mosquitoes. Interior Alaska (Fairbanks, Denali area) has the worst concentrations June-July. Southeast Alaska has fewer due to maritime winds.
- Prevention
- DEET 30-40% repellent; head nets ($8-15 at outdoor stores); treated clothing. Mosquitoes do not carry malaria or West Nile Virus in Alaska.
- Concern
- Altitude sickness
- Risk
- Low for visitors
- Details
- Most Alaska destinations are near sea level. Denali base camps start at 7,200 ft. Altitude sickness possible for mountaineers going above 10,000 ft.
- Prevention
- Acclimatize gradually; hikers ascending to high elevations should spend 1-2 days at 5,000-7,000 ft first
- Concern
- Sunburn / Snow blindness
- Risk
- High in summer
- Details
- The midnight sun means 24-hour UV exposure in summer. Snow and glacier reflections amplify UV intensity. Snowblindness (photokeratitis) can occur in hours without eye protection.
- Prevention
- SPF 50+ sunscreen; glacier/UV-rated sunglasses (100% UV400); sun hat in summer
Safety for specific travellers
Tailored advice for different groups.
Solo travellers
Alaska is a great destination for solo travelers who are well-prepared. Solo backcountry travel requires extra caution — carry a satellite communicator (Garmin inReach Mini, ~$400 purchase or $35/month plan) for emergencies, always file a trip plan, and be extra conservative about weather and trail conditions. Cities (Anchorage, Fairbanks, Juneau) are safe for solo travelers including after dark in tourist areas.
Female travellers
Alaska is generally safe for solo female travelers in cities and major tourist areas. Backcountry precautions (satellite communicator, trip plans, bear spray) apply to all genders. Female solo hikers should inform someone of their route. Anchorage, Juneau, and Fairbanks have active downtowns with normal urban safety awareness required.
Families
Alaska is an excellent family destination. Major parks and wildlife centers are well-equipped for children. Bear safety education (Alaska State Parks programs) is available at national park visitor centers. Water safety is important — all children should wear life jackets on water tours. Dress children in layered weather-appropriate clothing even in summer.
LGBTQ+ travellers
Anchorage and Juneau have active LGBTQ+ communities with annual Pride events. Alaska law prohibits discrimination based on sexual orientation and gender identity. Rural areas and small communities may be less welcoming — exercise normal discretion. The state overall is politically mixed but tourist areas are welcoming to all visitors.
