What to Pack for Alaska Cruise from Seattle 2026: Complete Packing List

Base layer: Moisture-wicking shirts (3-4), lightweight long underwear (2 sets). Mid layer: Fleece jacket or sweater (2), long-sleeve shirts (4-5). Outer layer: Waterproof rain jacket with hood (essential!), windbreaker. Pants: Jeans or travel pants (3-4), waterproof rain pants (1), leggings/thermal bottoms (2). Alaska temperatures: May 45-55°F, June-August 50-65°F, September 45-60°F. Mornings/evenings cold, afternoons moderate. Glacier viewing areas 10-15°F colder. Pack for 40-70°F range with rain assumption.

Waterproof hiking boots or shoes (primary footwear - will use daily). Comfortable walking shoes (backup pair). Sandals or flip-flops (ship pool area). Dress shoes (formal nights if desired). Warm socks (6-8 pairs) - wool or synthetic (cotton stays wet, avoid). Waterproof shoe covers or gaiters optional but useful. Most important: Broken-in waterproof boots. Alaska shore excursions involve walking, hiking, wet ground. New boots cause blisters. Test footwear on 3-5 mile walks before cruise.

Waterproof rain jacket with hood (non-negotiable - use daily). Waterproof rain pants (optional but recommended for rainy excursions). Compact umbrella (ship cabins, rain-protected decks). Waterproof gloves (lightweight, for glacier viewing). Warm hat/beanie (for windy deck viewing). Sunglasses (surprisingly bright despite clouds). Sunscreen SPF 30+ (sun reflects off water/glaciers). Lip balm with SPF. Alaska weather changes hourly - prepare for rain every day even if forecast shows sun.

Formal nights (1-2 on 7-day cruise): Men: Suit or sport coat with slacks, tie optional. Women: Cocktail dress, dressy pantsuit, skirt/blouse. Smart casual: Nice jeans, khakis, polo shirts, casual dresses (for main dining room). Day wear: Comfortable casual (jeans, t-shirts, shorts if warm). Alaska cruises less formal than Caribbean - 'Alaska casual' acceptable most nights. Many skip formal nights entirely, eat at buffet. Pack 1-2 nicer outfits if enjoying main dining room ambiance.

Binoculars (essential for wildlife viewing - whales, eagles, bears from ship). Daypack or small backpack (for shore excursions). Reusable water bottle (fill on ship, carry during hikes). Camera with telephoto lens (wildlife photos). Extra camera batteries (cold drains batteries fast). Waterproof camera case or dry bag. Motion sickness medication (Alaska waters rougher than Caribbean). Small first-aid kit. Bug spray (mosquitoes in rainforest areas). These items enhance Alaska experience significantly.

Skip: Shorts/tank tops as primary clothing (too cold). Swimwear beyond 1-2 pieces (hot tubs used, pools less so). Formal wear beyond 1-2 outfits (Alaska ultra-casual). Heavy winter coats (layering works better). Excessive dressy shoes (boots/sneakers primary). Beach bags (no beach days). Snorkel gear (water too cold). Cotton clothing (stays wet, choose synthetic/wool). Pack light - Alaska cruising about function over fashion. Most time spent layered in outdoor gear.
