What to Pack for Alaska
What to pack for Alaska is one question with one answer: layers plus real rain gear. A base layer that moves sweat off your skin, an insulating mid layer like fleece or a light puffy, and a genuinely waterproof outer shell with a hood. That system covers a 40-degree glacier morning and a 70-degree Anchorage afternoon in the same day, which is a completely normal Alaska summer. Add waterproof shoes, a warm hat and gloves even in July, bug protection for June and July, and a sleep mask for the near-endless daylight.

Updated September 2026. Weather in Alaska varies enormously by region and by day, and park regulations, bear safety guidance and cruise line dress policies change. Check the National Park Service bear safety pages before any backcountry time and confirm current conditions with your outfitter or cruise line close to departure.
The Layering System, Explained Once
Every good Alaska packing list is really this system with different words on top. Learn it and you can pack for any Alaska trip in any month.
| Layer | Job | Good choices | Never use |
|---|---|---|---|
| Base | Moves sweat away from skin so you do not get chilled | Merino wool or synthetic long-sleeve top and bottoms | Cotton, which holds water and steals heat |
| Mid | Traps warm air | Fleece, a light down or synthetic puffy, a wool sweater | A single very thick coat with nothing under it |
| Shell | Blocks wind and rain | Waterproof breathable jacket with a hood and sealed seams, plus rain pants | Water resistant jackets, which soak through in an hour |
Why cotton is the villain here. Wet cotton against skin in a 45-degree wind is how people get genuinely cold on a whale watching boat. Jeans are the most common version of this mistake. One pair for town evenings is fine, but do not plan a glacier day around them.
Why three thin layers beat one thick coat. You will move between a 40-degree deck, a heated bus, and a walk that makes you sweat, all within an hour. Layers let you shed and add. A single parka gives you two settings: too hot and too cold.
The rain shell is the item people cheap out on and regret. Southeast Alaska, where most cruises go, is temperate rainforest. Ketchikan and Juneau see rain on a large share of days in any given month, and "water resistant" gear fails in exactly that kind of steady, all-day drizzle. Look for a hood that adjusts, taped seams, and pit zips if you can get them.
What to Pack for Alaska in Summer
Summer, roughly mid-May through mid-September, is when most visitors go. It is also the season people underpack for, because "summer" suggests something Alaska does not deliver.
| Category | Bring | Notes |
|---|---|---|
| Tops | 2 base layers, 2 to 3 t-shirts, 2 long-sleeve shirts, 1 fleece, 1 light puffy | The puffy compresses to nothing and earns its space on every boat day |
| Bottoms | 2 pairs of quick-dry hiking pants, 1 pair of jeans or casual pants, rain pants | Convertible or roll-up pants are genuinely useful here |
| Outer | Waterproof shell with hood | The single most important item in the bag |
| Shoes | Waterproof walking shoes or light hiking boots, plus casual sneakers | Broken in, not new |
| Warmth | Warm hat, light gloves, buff or neck gaiter | Yes, in July. Glacier air and open water are cold |
| Sun | Sunglasses, sunscreen, brimmed hat | Snow, water and glaciers reflect hard and the sun sits up for hours |
| Bugs | Repellent with DEET or picaridin, plus a head net for June and July inland | Mosquitoes and no-see-ums are legendary near Denali and the interior |
| Sleep | Eye mask | In June, it barely gets dark, and in Fairbanks it effectively does not |
| Gear | Binoculars, camera with zoom, power bank, dry bag | Wildlife is usually farther away than photos suggest |
| Health | Motion sickness remedy, blister plasters, basic first aid | Small boat tours and the Gulf of Alaska crossing get rough |
The two items visitors most often forget: the warm hat, because it is July, and the eye mask, because they have never tried to sleep in daylight at 11 p.m. Both are small, cheap and trip-changing.
The binoculars point is not fluff. Bears, whales, Dall sheep and eagles are usually spotted at a distance. A pair of compact binoculars turns a distant brown dot into the memory you flew there for. One pair per two people is enough.
Trip Type Changes Everything
Alaska is not one trip. These four look very different in a suitcase.
| Trip type | What dominates | Add these | Skip these |
|---|---|---|---|
| Inside Passage cruise | Ship days, port towns, deck time, cool wind | One smarter outfit for dinner, binoculars, a day bag that zips, motion sickness remedy | Heavy hiking gear, formal wear beyond one outfit |
| Land tour or Denali | Long bus rides, hiking, bugs, dust | Head net, hiking boots, trekking poles, extra base layers, bear-aware habits | Anything dressy |
| Fishing or lodge trip | Water, rain, cold hands, fish smell | Rubber boots, waterproof gloves, a change of clothes for the boat, a dry bag | Nice clothes of any kind |
| Winter and northern lights | Extreme cold, standing still outside at night | Insulated parka, snow pants, insulated boots, balaclava, hand and toe warmers, spare camera batteries | Any single-layer plan |
If a cruise is your trip, our Alaska cruise packing list covers the ship-side items and the cruise packing list covers the basics that apply to any line, and if you are prone to nausea in a swell, read how to avoid motion sickness while traveling before you book your cabin, because cabin position matters on the Gulf of Alaska crossing.
For a land trip built around parks, the national park packing list and the hiking packing list cover the day-hike essentials, including the ten-essentials framework the Park Service teaches.
If Your Alaska Trip Is a Cruise
The layering system above is the whole foundation for a cruise too, but the ship adds its own problems: standing still on an open deck at a glacier, a day bag that has to survive a wet excursion, binoculars, the cabin, the dressier evening and how the conditions shift between May and September. All of that now lives on our Alaska cruise packing list. Read this page for the clothing system, then read that one for the ship.
Rain Gear: How to Choose It Properly
If you buy one new thing for Alaska, buy this.
- Waterproof, not water resistant. Look for a stated waterproof rating or a taped-seam construction. If the label only says "repellent" or "DWR finish", it will wet out in steady rain.
- A hood that adjusts and stays up in wind. Umbrellas are close to useless on a boat deck or a Juneau waterfront.
- Long enough to cover your hips when you sit on a wet bench or a boat seat.
- Rain pants, packable. They live in the day bag most of the time and become the best item you brought roughly twice a trip.
- Waterproof footwear. Wet feet on a five-hour excursion end the day early. In fishing towns and on lodge trips, plain rubber boots are the local uniform for good reason.
- A dry bag or heavy zip bag for the phone and camera. Spray is constant on small boats.
The layer people skip: wool socks. Two or three pairs of midweight wool socks are worth more than an extra sweater. They stay warm damp and they cut blisters on long walking days.
Bugs, Daylight and Wildlife: The Three Alaska Surprises
Mosquitoes. Alaska's inland summer bug season, roughly June into early August, is not a joke, and no-see-ums add a second problem near water. Bring repellent with DEET or picaridin, treat one set of clothing with permethrin before the trip if you will be inland, and pack a head net if Denali or the interior is on your route. A head net weighs almost nothing and buys back an entire evening.
Daylight. In June, Anchorage gets around 19 hours of daylight and Fairbanks essentially does not get dark. Curtains in lodges and cabins are often thin. An eye mask is the fix, and so is putting your phone away an hour before bed, since your body has no light cue to go on. If you are flying in from the East Coast, the time change plus the light can stack up, so read how to beat jet lag for the adjustment plan.
Wildlife distance. Bears, moose and whales are wild animals and the safe viewing distances are larger than they look. The Park Service guidance is to keep well back, never get between a moose and a calf or a bear and its food, make noise on trails so you do not surprise anything, and carry bear spray where it is recommended. Note that bear spray cannot fly in a carry-on or a checked bag, so plan to buy or rent it in Alaska and leave it behind when you go.
Winter and Northern Lights Trips
A winter trip to Fairbanks or the interior is a different kind of packing job, because you will be standing still outdoors, at night, for a long time, waiting for the sky to do something.
- An insulated parka rated for real cold, not a fashion coat, with a hood
- Insulated snow pants over your base and mid layers
- Insulated winter boots rated well below freezing, with wool socks
- Balaclava or face covering, insulated mittens rather than gloves, and a warm hat
- Hand and toe warmers, several packs, because standing still is the hard part
- Spare camera batteries kept in an inside pocket, since cold drains them fast
- A tripod if you are serious about photographing the aurora
- Moisturizer and lip balm, because interior winter air is extremely dry
Many aurora lodges and tour operators rent full arctic suits and boots, which is often smarter than buying gear you will use once. Ask before you buy. Our winter vacation packing list covers the general cold-weather kit, and our travel first aid kit guide notes the cold-specific additions.
What Not to Pack for Alaska
- An umbrella. Wind makes it useless. The hood does the job.
- Cotton base layers and cotton hoodies as your warm layer. Fine for the ship, wrong for a glacier.
- Formal wear. Even cruise dress codes have relaxed, and one smarter outfit covers it.
- Heels. Docks, gangways, gravel and boardwalks say no.
- Bear spray in your luggage. It is prohibited in checked and carry-on bags. Buy it there.
- Too many shoes. Two pairs, one of them waterproof, handles nearly every trip.
- A giant hard-shell suitcase for a small-plane or lodge trip, since bush flights have strict weight limits and often ask for soft duffels.
That last point catches people. If any leg of your trip is on a small plane to a lodge, ask about the weight allowance early. Duffels pack into a float plane in a way that hard cases do not, and the limits are much tighter than commercial airline rules.
A Simple Packing Method That Keeps the Weight Down
- Lay out the three layers first, before any other clothing. Base, mid, shell. That is your foundation for every day of the trip.
- Add one t-shirt or top per two days, not per day. You will re-wear things under layers and nobody will notice.
- Cap shoes at two pairs, one waterproof and worn on the plane.
- Add the small stuff that changes everything: hat, gloves, wool socks, eye mask, binoculars, repellent, power bank.
- Pack the day bag separately and keep it packed. It should never be unpacked into the closet, because you grab it every morning.
- Weigh the bag before you leave if a small plane or a tight airline allowance is involved.
- Leave a third of the bag empty. Alaska gift shops are good, and salmon ships home better than it packs.
Use the how to pack a suitcase method to fit bulky fleece and shells efficiently, and check your airline's rules with the carry-on size checker before you decide what flies in the cabin.
Alaska Packing FAQ
How cold is Alaska in the summer?
It depends on the region, but plan for daytime highs in the 50s and 60s in coastal and Southcentral areas, cooler on glaciers and open water, and warmer in the interior where summer days can reach the 70s or higher. Evenings and boat days are the cold part, which is why the warm hat and the puffy come along even in July.
Do I really need a warm hat and gloves in July?
Yes. Glacier viewing, whale watching and any open-deck time on a ship all involve cold wind and sometimes spray, even on a mild day. A thin hat and light gloves take almost no space and get used far more than people expect.
What shoes should I pack for Alaska?
Waterproof walking shoes or light hiking boots as your main pair, already broken in, plus one casual pair for the ship or town. Add rubber boots for a fishing or lodge trip and insulated winter boots for a cold-season visit. Skip heels and anything that soaks through.
Can I bring bear spray on the plane?
No. Bear spray is prohibited in both carry-on and checked bags. Buy or rent it after you arrive, and note that it cannot come home with you either. Many outfitters and park-adjacent stores rent canisters, which is the simplest option for a short trip.
What should I pack for an Alaska cruise specifically?
Start with the same layering system and waterproof shell described on this page. The ship-specific items, including deck clothing for glacier viewing, the excursion day bag, binoculars, dinner dress and month by month conditions, are covered on our Alaska cruise packing list.
Do I need bug spray in Alaska?
Inland, yes, especially June and July around Denali, the interior and anywhere near standing water. Coastal towns and cruise ports are much less buggy. Bring repellent with DEET or picaridin, and add a head net if you will be hiking inland.
Why do I need an eye mask?
Because in June it barely gets dark and in Fairbanks it effectively does not, and lodge curtains are often thin. Without a mask, many visitors sleep badly all week and blame the beds. It weighs nothing and it is one of the highest-value items on this list.
Before You Zip the Bag
Three checks. Is your outer layer actually waterproof, not just water resistant? Do you have a warm hat and wool socks even though it is summer? Is the day bag packed with the rain shell, binoculars and a power bank so you can grab it and go?
If all three are yes, Alaska is going to be easy. Generate your personalized version with the packing list generator, and if a cruise is the plan, read the Alaska cruise packing list for the ship-side items this page does not cover.
