Pack layers because Alaska weather changes fast, even in summer
Alaska cruise temperatures range from the low 50s to mid-60s Fahrenheit, even in peak summer months. What feels warm in the sun becomes cold in the shade or on the water within minutes. The single most important packing rule is to bring clothes you can layer — a t-shirt under a fleece under a waterproof jacket — rather than one heavy coat you cannot remove.
Rain is nearly may provide on an Alaska cruise. Bring a waterproof outer layer that fits over your other clothes, not a thin rain jacket that tears. Waterproof pants are worth the space; regular jeans stay wet and cold all day. Wool or synthetic socks (not cotton) dry faster and keep your feet warm when damp.
Bring more layers than you think you need. A typical day involves being outside on deck, then inside the ship's dining room, then outside again. You will change clothes multiple times. Pack at least four pairs of pants or leggings, six to eight shirts, two fleeces or sweaters, and one heavy insulated jacket.
Key Takeaways
- Layer your clothing with t-shirts, fleeces, and a waterproof outer jacket because temperature swings happen throughout the day.
- Waterproof pants and a quality rain jacket are essential; regular jeans and thin rain gear will leave you cold and wet.
- Bring sturdy waterproof hiking boots or shoes with good grip, because shore excursions involve wet rocks, mud, and uneven terrain.
- Pack binoculars, a camera with extra batteries, and sunscreen even though Alaska feels cool — the sun reflects off water and snow.
- Bring motion sickness medication if you are prone to seasickness, because the Inside Passage can have rough water on certain days.
Footwear that handles wet ground and uneven surfaces
Most Alaska cruises include at least one shore excursion — hiking, kayaking, or walking through a town. The ground is wet, muddy, or covered in loose gravel. Smooth-soled shoes or sandals will slip. Bring waterproof hiking boots or trail shoes with a thick tread and ankle support. Merrell, Salomon, and Keen make boots designed for this exact terrain and dry reasonably fast.
Bring two pairs of footwear: one for hiking and one for casual wear around town or the ship. Waterproof slip-on shoes or clogs work well for the second pair because you can remove them quickly when boarding the ship. Avoid canvas sneakers; they absorb water and stay wet for days.
Pack wool or synthetic socks specifically for hiking, plus regular socks for everyday wear. Bring at least six pairs total. Wet feet are the fastest way to become miserable on a cruise.
Outerwear and rain gear that actually works
A single heavy winter coat is not the answer. Instead, bring a mid-weight insulated jacket (down or synthetic) that you can wear over layers, plus a separate waterproof shell jacket. This combination lets you adjust to temperature swings without carrying bulk.
The waterproof jacket should be a true rain shell — not a water-resistant fabric, but fully waterproof with sealed seams. Brands like Columbia, The North Face, and Helly Hansen make jackets designed for wet climates. Avoid anything that crinkles or feels thin; it will tear on rocks or branches during a hike.
Waterproof pants are less common in luggage but worth the space. If you slip on wet rocks or sit on a damp bench, regular pants will stay wet and cold for hours. Waterproof hiking pants pack down small and dry quickly.
Accessories that protect against sun, wind, and cold
Sunscreen is counterintuitive in cool weather, but Alaska's sun reflects off water and snow. Use SPF 30 or higher on your face and hands, even on cloudy days. Bring a stick sunscreen for your nose and lips because it does not wash off as easily as lotion.
A hat with a brim protects your face and keeps sun out of your eyes when looking for wildlife. A beanie or fleece hat keeps your head warm on deck. Bring both.
Gloves are useful for early morning or evening deck time. Wool or synthetic gloves dry faster than cotton. A scarf or neck gaiter adds warmth without taking up much space and can cover your face if wind picks up.
Sunglasses reduce glare off the water and protect your eyes during long periods outside. Bring a strap to keep them from falling overboard.
Camera gear and binoculars for wildlife viewing
Alaska cruises are built around seeing bears, whales, eagles, and glaciers. A camera with a zoom lens is more useful than a smartphone for distant wildlife. If you own a DSLR or mirrorless camera, bring it. If you do not, a point-and-shoot camera with optical zoom works well and takes up less space.
Binoculars are essential for spotting wildlife before it disappears. Bring binoculars with at least 8x magnification. They do not need to be expensive; a $50 pair from a sporting goods store will show you bears and whales clearly.
Pack extra batteries for your camera. The cold drains batteries faster, and you will take hundreds of photos. Bring at least two extra sets. A memory card with high capacity prevents you from running out of storage mid-cruise.
Medications and health items for seasickness and minor injuries
Motion sickness medication is worth bringing even if you rarely get seasick. The Inside Passage can have rough water, and being stuck in your cabin is the worst way to spend a cruise day. Dramamine, Bonine, or prescription scopolamine patches all work. Start taking medication before you feel sick, not after.
Bring a basic first aid kit: blister treatment, pain relievers, antacids, and anti-diarrhea medication. Hiking and walking on uneven ground cause blisters. Ship pharmacies charge high prices for common items.
If you take prescription medications, bring enough for the entire trip plus a few extra days. Keep medications in their original bottles with your name on them. Bring copies of prescriptions in case you need a refill.
Formal wear and casual clothes for dining and downtime
Most Alaska cruises have one or two formal or semi-formal dining nights. Check your cruise line's dress code before packing. If formal night is required, bring one dress or suit and dress shoes. If semi-formal is the standard, business casual (slacks and a button-up shirt) is sufficient.
Pack casual clothes for everyday wear: jeans, leggings, t-shirts, and sweaters. Bring clothes you do not mind getting dirty or wet. Bring a swimsuit if the ship has a pool or hot tub, though many Alaska cruises do not.
Pack a light robe or cardigan for moving between your cabin and the dining room. Bring undergarments and sleepwear for the entire trip. Ships have laundry services, but they are expensive; packing enough clothes to go a week without laundry saves money.
Toiletries and personal items to bring versus buy onboard
Ships provide basic toiletries like soap and shampoo, but they are often low quality. Bring your own shampoo, conditioner, and body wash if you have sensitive skin or preferences. Bring deodorant, toothpaste, and a toothbrush.
Bring medications you use regularly: allergy medication, pain relievers, heartburn medication, and any prescription drugs. The ship's medical center charges for visits and medications.
Bring a small amount of laundry detergent if you plan to wash clothes in your cabin. Most cabins have a sink but no washing machine. Hand-washing socks and underwear saves luggage space.
Leave behind: full-size bottles of anything. Bring travel sizes or decant into small containers. Cruise cabins are small, and you will not use a full bottle of lotion in a week.
Luggage and packing strategy to stay within limits
Most cruise lines allow two checked bags per person plus a carry-on. Pack your heaviest items (boots, jacket, camera) in checked luggage to keep your carry-on light. Pack a change of clothes and medications in your carry-on in case your checked bag is delayed.
Roll clothes instead of folding them to save space. Use packing cubes to organize by category (layers, hiking gear, formal wear). This makes finding items easier in a small cabin.
Wear your bulkiest items during travel — your hiking boots and heavy jacket — rather than packing them. This saves luggage space and keeps them accessible.
Pack a small day backpack (10 to 15 liters) for shore excursions. You will need space for a water bottle, camera, sunscreen, and a light layer. A backpack is easier to manage than a purse when hiking or kayaking.
Frequently Asked Questions
Do I really need waterproof pants, or will regular jeans work?
Regular jeans absorb water and stay cold and heavy for hours. If you slip on wet rocks or sit on damp ground during a hike, you will be miserable. Waterproof pants are lightweight, pack small, and dry in minutes. They are worth the space.
What if I forget something important?
Most Alaska cruise ports have general stores where you can buy basics like socks, sunscreen, or a hat. Prices are higher than at home, but you can replace forgotten items. The ship's gift shop also carries some clothing and toiletries.
How much luggage space do I need for a week-long Alaska cruise?
A standard rolling suitcase (24 to 28 inches) holds a week's worth of clothes if you pack efficiently. Bring one checked bag plus a carry-on with essentials. If you are traveling with a partner, one large bag per person is usually enough.
Should I bring a dry bag for hiking and water activities?
A dry bag is useful if you are doing kayaking or other water excursions where your belongings might get wet. A 10 to 15-liter dry bag costs $20 to $40 and protects your camera, phone, and wallet. If your excursions are land-based only, a regular backpack with a rain cover works fine.
Is it worth bringing my own binoculars, or can I rent them onboard?
Bringing your own binoculars saves money and ensures you have a pair you trust. Rental binoculars are often low quality and availability is limited. If you do not own binoculars, buy an affordable pair ($30 to $60) before the cruise rather than renting onboard.
