What to Pack for an Alaska Cruise with Kids
An Alaska Inside Passage cruise is an extraordinary family adventure featuring calving glaciers, breaching humpback whales, and temperate rainforest ports. However, Alaskan maritime weather is notoriously unpredictable—temperatures fluctuate by 30°F, and rainfall is frequent.
Updated August 2026
Quick answer
For a 7-night Alaska family cruise (Juneau, Skagway, Ketchikan, Glacier Bay), expect 50–65°F (10–18°C) with frequent rain and sub-40°F winds near glaciers. Pack a strict 3-layer system: thermal base layers, fleece or down mid-layers, and 100% waterproof seam-sealed rain jackets (not just water-resistant), compact 8×42 binoculars, waterproof trail shoes, and magnetic hooks for cabin walls.

Essential gear for an Alaska family cruise
- •The golden rule of Alaska cruising is the 3-layer system: (1) Moisture-wicking base layer, (2) Insulating fleece or lightweight puffer jacket, (3) 100% waterproof, windproof rain shell jacket with a hood.
- •Ketchikan is in a temperate rainforest receiving over 150 inches of rain annually. Water-resistant windbreakers will soak through in 20 minutes; pack true waterproof breathable jackets (Gore-Tex or nylon with taped seams) and waterproof pants for kids.
- •Glacier Bay viewing day on deck: When the ship spends 6 hours idling in front of Margerie Glacier, standing on open observation decks in freezing katabatic winds requires warm beanies, fleece neck gaiters, and gloves even in mid-July.
- •Pack at least 2 pairs of compact binoculars (8×42 or 10×42 magnification). Spotting bald eagles in treetops, harbor seals on floating icebergs, and humpback whale spouts from your stateroom balcony requires good optics.
- •Footwear: Pack waterproof low-cut hiking shoes or treated sneakers for walking in port excursions (Mendenhall Glacier trails, rainforest boardwalks). You don't need heavy mountaineering boots.
- •Cabin magnetic hooks: Ship walls are steel; heavy-duty magnetic hooks are vital for hanging wet rain jackets, daypacks, and binoculars to dry.

Seasonal things to plan around

- Jul–AugMosquitoes in inland excursions (Yukon / Skagway). Pack picaridin insect repellent.
Common Alaska cruise packing mistakes
- •Packing heavy, bulky winter ski parkas that take up half a suitcase. A 3-layer shell + fleece system is lighter, more comfortable, and easily adaptable.
- •Forgetting seasickness medication. Sailing through open waters (like Queen Charlotte Sound or the Gulf of Alaska) can produce significant ocean swells.
- •Packing only 1 pair of binoculars for the whole family, causing kids to fight over who gets to see the whale.
- •Assuming summer in Alaska means warm sunny weather; average summer temperatures in Juneau rarely exceed 65°F.
FAQ
Do kids need passport books for an Alaska cruise?
Cruises sailing round-trip from Seattle (closed-loop) allow US children under 16 to travel with an official birth certificate, but cruises starting or ending in Vancouver, Canada require valid passports for all passengers.

Yes! Most Alaska cruise ships have heated outdoor pools and hot tubs, and some ships (like Disney or Princess) have covered indoor solarium pools or retractable glass roofs.
What is the best month for an Alaska family cruise?
July and August offer the warmest temperatures, peak salmon runs, and the highest whale and bear activity, though June has the longest daylight hours and lowest rainfall.
