Alaska Cruises: Where to Start
Alaska cruises generally fall into two route types: Inside Passage itineraries, which are round-trip from Seattle or Vancouver and stay in sheltered coastal waters, and Gulf of Alaska (one-way) itineraries, which sail between Vancouver or Seattle and Anchorage/Whittier, often paired with a land tour to Denali.
The season runs roughly late April through early October, with June through August considered peak season for the best weather and longest daylight hours. Major ports of call typically include Juneau, Ketchikan, Skagway, and Sitka, each known for different highlights - glaciers, wildlife, gold rush history, and Native Alaskan culture.
Nearly every major cruise line - Royal Caribbean, Princess, Holland America, Norwegian, Celebrity, and Carnival - runs Alaska seasons, along with luxury and expedition lines for a smaller-ship experience. Call +1-800-406-8495 to compare which line and route fits your travel dates best.
Frequently Asked Questions
What's the difference between Inside Passage and Gulf of Alaska cruises?
Inside Passage cruises are round-trip from Seattle or Vancouver and stay in protected coastal waters. Gulf of Alaska cruises are one-way between Vancouver/Seattle and Anchorage/Whittier, often combined with a land tour inland.
When is the best time to cruise Alaska?
June through August is peak season with the longest days and mildest weather, though late May and September can offer lower prices and fewer crowds.
Which cruise lines sail to Alaska?
Most major lines run Alaska seasons, including Royal Caribbean, Princess, Holland America, Norwegian, Celebrity, and Carnival, plus smaller luxury and expedition operators for a more intimate experience.
Do I need a passport for an Alaska cruise?
It depends on your itinerary - closed-loop cruises from a US port may not strictly require one, but a passport is recommended, and definitely required if your cruise calls at a Canadian port like Victoria.
What should I pack for an Alaska cruise?
Layers are key - waterproof outerwear, warm layers for cool mornings and evenings, and comfortable walking shoes for shore excursions like glacier hikes or wildlife tours.
What's the difference between a big-ship and small-ship Alaska cruise?
Big-ship cruises visit major ports with more onboard amenities, while small-ship expedition cruises access narrower fjords and remote wildlife areas that larger ships can't reach.
Can I see the northern lights on an Alaska cruise?
It's possible on early or late-season sailings with darker night skies, though it's not guaranteed and depends on clear conditions and solar activity.
Do all Alaska cruises visit a glacier?
Most itineraries include some form of glacier viewing, whether a scenic cruising day or a port stop near a tidewater glacier, though the specific glacier varies by route.
Is it worth taking a helicopter or floatplane tour in Alaska?
Many past cruisers rate flightseeing tours as a trip highlight, especially those landing on a glacier, though they add a notable cost on top of the cruise fare.
Are Alaska cruises family-friendly?
Yes, most mainstream cruise lines sailing Alaska offer full kids' programs alongside wildlife and glacier viewing that appeals to all ages.
