Alaska Cruises: The Complete 2026 Guide
Glaciers, wildlife, and the Inside Passage — here’s everything you need to plan an Alaska cruise, from itinerary types to packing.
An Alaska cruise is less about ports and more about scenery: calving glaciers, humpback whales, and towering fjords seen from the deck. Sailings run primarily May through September on Royal Caribbean, Norwegian, Celebrity, Princess, Carnival and Disney, on Inside Passage round-trips and one-way Gulf of Alaska itineraries.

Seattle or Vancouver?
Seattle round-trips are easiest for US travelers: a domestic flight, no Canadian customs, and a required stop in Victoria, BC. Vancouver sailings often include more scenic Inside Passage cruising and are the starting point for most one-way Gulf of Alaska routes. Everyone sailing from Vancouver needs a valid passport. From New Hampshire, both cities are a single connection away from Boston or Manchester.
Cruisetours: Adding Denali
A cruisetour pairs your sailing with 3–6 nights on land, typically visiting Denali National Park, Talkeetna, Fairbanks or Anchorage by rail and motorcoach. Princess operates the largest network of its own wilderness lodges and dome rail cars. Royal Caribbean and Celebrity also offer land packages. Cruisetours are best booked early since lodge capacity is limited.
Choosing a Cabin for Alaska
Alaska is the one itinerary where a balcony earns its price. Hours of scenic cruising past glaciers, fjords and wildlife are far more comfortable from a private balcony than from a crowded rail. Mid-ship balconies on lower decks reduce motion in the open Gulf of Alaska. If a balcony doesn’t fit your budget, choose a ship with generous forward observation spaces. See is a balcony worth it?

What an Alaska Cruise Costs
Alaska fares are typically higher per night than the Caribbean because of the short season and demand for balconies. Excursions also cost more: helicopter glacier landings, floatplane tours and the White Pass railway can each run well into the hundreds of dollars per person. Budget for flights to Seattle, Vancouver or Anchorage, a pre-cruise hotel, and layered clothing. Our Alaska cruise planning tips and Alaska excursions guide help you prioritize.
