Alaska Cruise From San Francisco (and Los Angeles): 2027 Ships, Itineraries, Costs and Who Should Skip It

If you live in California, this trip sounds almost too easy. No flights, no airport hotel, and you sail out past the Golden Gate Bridge with your own pillow in the trunk. It really can be that easy.

The catch is the brochure doesn't mention it. You're buying a longer trip with more open-ocean days. Some people love that. Others start pacing the Lido deck by day three.

Below: the 2027 ships, a real day-by-day itinerary, what it costs (as of October 2026), how Los Angeles compares, and who should honestly book Seattle instead.

How long is an Alaska cruise from San Francisco?

Plan on 10 nights. Princess and Carnival both run 10-night round trips, and Carnival adds a single 11-night sailing in September 2027. Seattle's standard is 7 nights.

The Alaska part is about the same either way. The extra days are sea days. On the Carnival schedules I checked, you get two straight sea days heading north and two more coming home.

Cruise lines count nights, and everyone else counts days, so “10-night” and “11-day” are the same trip. You board on day 1 and walk off on day 11.

The season is short. Princess's Ruby Princess sailings run from early May to early September 2027, and Carnival's fit inside that window. If you're still picking a month, my month-by-month guide to the best time to cruise to Alaska covers early-season versus peak-summer trade-offs.

Which ships sail from San Francisco in 2027?

I found two lines running Alaska round trips from San Francisco next year. Here's what each one is doing.

Princess: Ruby Princess, 10 nights

Princess's 2027 Alaska announcement lists Ruby Princess on a 10-day Inside Passage itinerary from San Francisco with Endicott Arm and Dawes Glacier.

The individual sailings are messier than that one line suggests. Listings on booking sites show some dates with Ketchikan, Juneau, Skagway and Dawes Glacier, and others with Sitka, Haines and either Tracy Arm or Glacier Bay. Every Ruby Princess sailing I found used Prince Rupert, B.C. as the Canadian stop, and departures I checked left at 3:00 pm.

So compare sailings, not just prices. The glacier day is why most people go, and it changes by date.

Carnival: Carnival Luminosa, 10 nights (and one 11)

Carnival's 10-night round trips call at Juneau, Skagway, Ketchikan and Prince Rupert, with a day of scenic fjord cruising in between. In 2027 they run from early May through August 23. The 11-night sailing on September 6 adds Sitka.

Carnival tends to be the livelier, lower-fare choice. Confirm the details on Carnival's own site before you book, since I pulled these from booking-site listings of its schedule.

What a real 10-night itinerary looks like

This is the Carnival Luminosa round trip leaving May 3, 2027, based on booking-site listings of Carnival's schedule. Other 10-night sailings I checked (late June, late July, August 9) use the same pattern and times. Treat it as the shape of the trip.

Look at Juneau. You arrive mid-afternoon and stay into the night, which is fine for a whale watch or a late glacier trip but not for an all-day adventure. Skagway is your long day (7 am to 8 pm), so save the big excursion for there. My guide on booking Alaska excursions with the ship or on your own explains how port timing changes that choice.

One more thing: some sailings list Ketchikan at Ward Cove, which sits outside downtown. Plan on a shuttle or taxi if you want to wander the waterfront.

What about an Alaska cruise from Los Angeles?

Los Angeles is an outlier. Princess lists Emerald Princess on two 16-day round trips with Glacier Bay National Park in 2027. The listings I found show departures on April 27 and September 18.

That's a long haul. The April 27 sailing starts with four straight sea days before Juneau, and the route also calls at Skagway, Icy Strait Point, Sitka, Ketchikan and Victoria, B.C. The upside is lots of time on board and a slow shift from palm trees to glaciers.

Cruise ships for Los Angeles generally leave from the San Pedro and Long Beach area, roughly 20 miles south of LAX. Your cruise documents will tell you which terminal. If you're flying in, arrive a day early. For a hotel, I'd start with these Long Beach hotels.

Pricing varies by source. Aggregator listings in October 2026 showed about $2,300 per person for the 2027 sailings, though the cabin type wasn't always stated. That's somewhere around $140 a night. A lot of ship for the money, but only if you have more than two weeks.

San Francisco vs Los Angeles vs Seattle: which departure fits you?

Seattle runs weekly sailings. Princess alone has Star Princess every Sunday and Royal Princess every Saturday, which makes it easy to fit around a vacation week. If that's tempting, read my Alaska cruise from Seattle guide or see how to pick between Vancouver and Seattle.

How much does it cost?

These are ranges from third-party booking sites in October 2026, not quotes. Prices move daily with month, cabin and promotions.

• Carnival 10-night, interior: about $1,050 per person for the May 3 sailing, climbing to roughly $1,370 for July 12, taxes and fees included. Late August sailings listed around $1,100.
• Princess 10-night, interior: roughly $1,300 to $1,500 for the July Ruby Princess sailings I found. Expect it to run a bit above Carnival.
• Princess 16-night from LA: about $2,300 per person on 2027 listings, with cabin type not always stated.

On Carnival, early May and late August sailings listed cheaper than July. Check the dates you can actually do before assuming anything.

The honest money angle is what you don't pay for. If you can drive, you skip airfare, an airport hotel and baggage fees. That can offset a good chunk of the extra nights.

Pier 27, passports and the Canada stop

Where you board in San Francisco

Most ships board at the James R. Herman Cruise Terminal at Pier 27 on The Embarcadero, which opened in 2014. The Port of San Francisco's cruise page has the official port details.

Check your boarding documents anyway. Princess's port guide says Pier 35 may be assigned when multiple ships are in port. It also says taxis and private vehicles can't wait at the curb unless they're actively loading or unloading, so plan a quick drop-off.

Driving yourself? Confirm parking with the Port of San Francisco and your cruise line before sailing day. I'd plan on an off-site garage or a rideshare rather than counting on parking at the terminal.

If you want a night in the city first, I'd book a hotel near the Embarcadero through Expedia. A Viator tour is handy if you'd like someone else to plan your extra day.

Do you need a passport?

Not necessarily. CBP's WHTI page says U.S. citizens on closed-loop cruises (same U.S. port out and back) can enter the U.S. with a birth certificate and government-issued photo ID. This trip qualifies, since it starts and ends in San Francisco. Children under 16 need only a birth certificate.

Note the birth certificate part. A driver's license alone, even a REAL ID, shows identity but not citizenship.

I'd still bring a passport. If a medical emergency means flying home from a foreign port, or you miss the ship in Prince Rupert, a birth certificate won't get you far.

Why your ship stops in Canada

The Passenger Vessel Services Act generally requires foreign-flagged ships that carry passengers between U.S. ports to call at a foreign port. That's why the San Francisco sailings I checked add Prince Rupert, and the Los Angeles ones add Victoria.

Who should skip this and sail from Seattle instead

I like this itinerary for the right person. Here's who I'd steer elsewhere.

• You only have 8 or 9 days off. The cruise alone is 10 nights, before you add travel to the pier.
• You get seasick easily. The first two days are on the open Pacific, which can be bumpier than the sheltered Inside Passage. Ask your doctor about options. Some people also try acupressure wristbands.
• You want multiple glacier days. The sailings I checked each had one scenic glacier or fjord day.
• You want a Denali land tour. Those pair more naturally with one-way cruisetours that end in Whittier or Anchorage.
• You're flying in from far away. Without the drive-up savings, the case for San Francisco gets weaker.

If you like ship life, want an easy start, or live within driving distance, it's a good option. Traveling with kids? My guide to the best family cruise to Alaska will help you compare ships.

Your questions, answered

One last thing before you book

Here's how I'd decide. Count your vacation days first. Then picture day three, with the ship still at sea and Alaska nowhere in sight. If that sounds like a relief, San Francisco is hard to beat. If it sounds like wasted time, Seattle probably fits better.

Either way, don't just grab the cheapest fare. Find out which glacier you'll see, then pick the cabin. For the bigger picture, my Alaska cruises hub pulls everything together.
