An Alaska cruise trades sea days in warm water for glaciers, brown bears, salmon-pink sunsets and old gold-rush towns. Most sailings run May to September, leave from Seattle or Vancouver, and last 7 to 11 nights. The choices that matter are the season, the route, the cruise line and the ship. This guide walks through each one.
An Alaskan cruise looks simple to book until you start comparing options. A 7-night round-trip from Seattle is a different holiday from a 7-night one-way Seward to Vancouver. Glacier Bay is on some itineraries, not others. June pricing is not May pricing.
Some routes focus on the Inside Passage and the panhandle ports of Juneau, Skagway and Ketchikan. Others cross the Gulf of Alaska to Hubbard Glacier and Whittier, and pair the cruise with a land tour up to Denali. Ship size matters too, since the largest classes cannot enter the narrower fjords.
This guide pulls those decisions apart. Our specialists book Alaska sailings every week and can match you to the right ship, route and cabin grade for an Alaska cruise in 2026 or 2027.
Which cruise lines sail to Alaska and what makes them different?
There is no single best line for Alaska. Each one runs a different mix of ships, ports and inland add-ons. The split below covers the big six in the UK market plus the 2026 newcomers.
Celebrity Cruises runs Celebrity Solstice, Edge and Eclipse on 7-night Inside Passage and Gulf of Alaska routes. The cabins skew modern, the dining is the main draw, and the Cruisetour add-ons cover Denali and the Yukon.
Cunard sails Queen Elizabeth out of Vancouver on 10 to 12-night routes that include scenic cruising at Hubbard Glacier. The atmosphere is more traditional, with formal evenings, afternoon tea and a stronger focus on lectures and enrichment.
Holland America has sailed Alaska since 1947 and holds one of the largest Glacier Bay National Park permit allocations alongside Princess. Eurodam, Nieuw Amsterdam and Westerdam cover the 7-night round-trips and one-ways, and the line bundles cruise plus land at Denali into a single booking.
Norwegian Cruise Line deploys Norwegian Bliss, Encore and Joy out of Seattle. These were built for Alaska, with an observation lounge that runs the width of the ship. NCL does not have a Glacier Bay permit, so its routes call at Endicott Arm or Dawes Glacier instead. The Free at Sea bundle (drinks, Wi-Fi, shore excursion credit, speciality dining) is the headline fare structure.
Princess Cruises has the largest Glacier Bay allocation. Discovery Princess, Sapphire Princess, Royal Princess, Ruby Princess and Coral Princess cover 7-night round-trips from Seattle and the 10 or 11-night Voyage of the Glaciers between Vancouver and Whittier. The Cruisetour programme reaches Denali, Talkeetna and Fairbanks.
Royal Caribbean runs larger ships such as Anthem and Ovation of the Seas out of Seattle, with North Star observation pod and FlowRider on board. Best suited to families and groups who want a big-ship sea day rather than a quieter destination focus.
Carnival Spirit and Carnival Luminosa give a cheaper entry point from Seattle, with 7-night Glacier Bay sailings. The atmosphere is casual and family-led.
For 2026, MSC Cruises adds Alaska from Seattle for the first time, Virgin Voyages brings its adults-only Brilliant Lady to Seattle on 7-night routes (Virgin sails from Portsmouth in the UK; its Alaska programme is a fly-cruise), and Azamara returns with longer port days on its smaller R-class ships.
Which ports do Alaska cruises depart from?
The departure port sets the shape of the route. Round-trips run from Seattle and Vancouver. One-ways link Vancouver with Seward or Whittier.
Seattle is the busiest US port for Alaska sailings. By law, foreign-flagged ships on a round-trip from a US port must call at a foreign port on the way, so almost every Seattle round-trip includes a short stop in Victoria, British Columbia. NCL, Royal Caribbean, Princess, Holland America and Celebrity all run from Pier 91. Direct flights from London Heathrow to Seattle make it the simplest connection from the UK.
Vancouver is the Canadian alternative and the home port for Princess Voyage of the Glaciers and most one-way Gulf of Alaska sailings. Cruises from here skip the Victoria detour and reach Ketchikan on day two, giving more time in Alaska itself.
Seward and Whittier are the Alaska-side ends of the one-way Gulf routes. Both connect by coach or the Alaska Railroad to Anchorage. If you want to add Denali National Park, fly into or out of Anchorage and use one of the Cruisetour packages.
Anchorage and Fairbanks are not cruise ports. They appear on Cruisetour itineraries as land-only nights, usually paired with rail travel to Denali.
When is the best time to visit Alaska?
The cruise season is May to September. Each month sails the same itineraries but the experience changes.
May is shoulder season. Cabin fares are lower, ports are quieter, mosquito and midge numbers are down, and the wildlife is waking up after winter. Land temperatures sit around 9 to 14°C, so warm layers matter on deck. Snow still caps the mountains, which is hard to find later in the summer.
June brings the longest daylight of the year. Juneau gets 18 to 19 hours of usable light, and salmon fishing season opens. Conditions are more settled than May and prices climb. This is when most repeat Alaska cruisers book.
July is the warmest month, with land temperatures from 16 to 22°C and the biggest crowds onshore. White Pass railway tickets, Mendenhall helicopter slots and Tracy Arm catamaran tours sell out furthest in advance. Expect peak pricing on cabins.
August still runs warm but the salmon runs peak, which pulls bears down to the rivers and bald eagles to the coast. Good month for wildlife photography. Pricing eases towards the end of the month.
September is the second shoulder. Fares drop, the leaves on the cottonwoods turn, and the Northern Lights window opens from around the third week of the month onwards. Rain is more likely.
Whichever month you choose, take layers. A waterproof shell, a fleece and a hat will cover most days on deck.
What are the must-see destinations in Alaska?
A 7-night Inside Passage round-trip from Seattle typically calls at three to four ports plus one scenic-cruising day. The headline stops are below.
Juneau is the state capital and the most visited port. From the cruise pier you can ride the Mount Roberts Tramway, take a helicopter to land on Mendenhall Glacier, or join a whale-watching boat into Auke Bay. The salmon bake at Gold Creek is a long-running excursion if you want a meal off the ship.
Skagway is the gold rush town. The White Pass and Yukon Route Railway leaves from the dock and climbs to 2,865 feet on a narrow-gauge line built in 1898. It is the excursion that books out earliest in July.
Ketchikan is the rain capital, with around 3.8 metres of rainfall a year, and the densest collection of totem poles in the world. The Misty Fjords floatplane tour is the standout excursion here.
Sitka is a quieter port with Russian Orthodox heritage from the days when Alaska was a Russian colony. Smaller ships call here, larger ones sometimes substitute it for Icy Strait Point.
Icy Strait Point is a purpose-built cruise call near Hoonah, a Tlingit village, and runs the longest ZipRider zip line in the world. Whale sightings are reliable in the surrounding Icy Strait.
The scenic-cruising day is the centrepiece for most travellers. Glacier Bay National Park sits at the top of the list and is restricted by US Park Service permits, which is why Princess and Holland America dominate that itinerary. Lines without a Glacier Bay permit sail Hubbard Glacier (the largest tidewater glacier in North America) or Tracy Arm and Endicott Arm instead. All three give long, slow approaches to a calving glacier face.
What types of cruise ships sail to Alaska, and how do I choose the right one for me?
Ship size shapes which ports you reach and how the sea days feel. There are four bands of ship sailing to Alaska.
Large ships (3,500+ passengers) include Norwegian Bliss, Norwegian Encore, Discovery Princess, Anthem of the Seas and Ovation of the Seas. They carry the full suite of speciality restaurants, theatres, kids clubs and observation lounges. Trade-off: they cannot enter Tracy Arm or Endicott Arm, so any narrow-fjord scenic day will be replaced by Hubbard Glacier or a Glacier Bay run for ships that hold a permit.
Mid-sized ships (2,000-3,000 passengers) include Eurodam, Nieuw Amsterdam, Westerdam, Sapphire Princess and Coral Princess. They reach into Tracy Arm and Endicott Arm, the Holland America and Princess permits cover Glacier Bay, and the lounges are quieter on a sea day.
Smaller ships (under 1,000 passengers) include the Azamara R-class. Slower pace, longer port days, and access to ports the big ships skip. Fewer onboard venues. Suits travellers who want the destination to lead.
Premium and luxury ships such as Queen Elizabeth (Cunard) and Azamara R-class focus on extended stays in port, higher staff-to-guest ratios and included shore experiences. Fewer family facilities, fewer waterslides, more lectures and live music.
A balcony cabin is the upgrade that pays back hardest in Alaska. The scenic-cruising day at Glacier Bay or Hubbard runs four to six hours, and a private balcony means you watch the ice without queueing on a public deck. For UK travellers in 2026, inside cabins from Seattle start around £999 to £1,400 per person on a 7-night sailing, balconies £1,800 to £2,400 per person, and suites from £3,500 per person.
What shore excursions are available on Alaskan cruises, and what do they involve?
Alaska shore excursions divide into five rough categories. Book the popular ones at the time you book the cruise, since the limited-capacity ones sell out months ahead.
Wildlife. Whale-watching boats out of Juneau and Icy Strait Point operate from May to September. Humpbacks and orcas are reliable from June onwards. Some operators offer a sightings guarantee in writing. Bear-viewing flights from Ketchikan or Sitka into Pack Creek or the Anan observatory run in July and August and are limited by permit.
Glaciers. The Mendenhall Glacier helicopter trek from Juneau lands you on the ice with crampons for a 40-minute walk. The Tracy Arm Fjord catamaran day-trip from Juneau covers ground a larger cruise ship cannot reach. The flightseeing run over Misty Fjords from Ketchikan is the alternative on a rainy day.
History and culture. The White Pass and Yukon Route Railway from Skagway is the headline. The Saxman Native Village tour from Ketchikan covers totem carving with a Tlingit guide. The Russian Bishop’s House in Sitka covers the colonial era.
Active. ZipRider at Icy Strait Point is the longest in the world at 1,300 metres of cable. Sled dog summer camps near Juneau and Skagway swap snow for wheeled rigs in July. Kayak tours run from most ports.
Food. The salmon bake at Gold Creek in Juneau is the long-running classic. Crab feasts in Ketchikan are the other one to look at.
Excursions book either through the cruise line or independently. Cruise-line excursions guarantee the ship will not sail without you if the tour runs over. Independent operators sometimes work out cheaper but the risk sits with you.
What should I pack for an Alaskan cruise to stay comfortable?
Alaska weather changes hour by hour, especially in May and September. Pack layers, not outfits.
The base layer is a thermal top and bottom for cold sea days at the glaciers. The middle layer is a fleece or a wool jumper. The outer layer is a waterproof shell with taped seams. A hat and a pair of light gloves cover the early-morning hours on deck at Glacier Bay or Hubbard, even in July.
Onboard, the daytime dress code is casual. Evenings on Princess, Holland America and Celebrity include two formal nights on a 7-night cruise. NCL and Royal Caribbean have no formal nights. Cunard runs three gala evenings on its 10-night sailings.
Waterproof walking shoes matter more than a smart pair. Ketchikan and Juneau are wet ports, and the cobbles in Skagway hold water.
Extras worth bringing: binoculars (8×42 is the standard for whale-watching), a camera with a zoom lens, polarised sunglasses for ice glare, and a small daypack for shore days. A reusable water bottle saves money on the ship, and a dry bag protects phones and cameras on rib-boat excursions.
Travel documents: a UK passport with at least six months’ validity, an ESTA for the United States, and an eTA for Canada if your cruise touches Vancouver or Victoria.
Is an Alaskan cruise suitable for families?
Yes, with one caveat. The scenic-cruising day at the glacier runs four to six hours of slow steaming. Younger children will need entertainment, which large ships cover with kids clubs that stay open across scenic days.
Wildlife is the universal hook. Humpback breaches, bald eagles on the railings, sea otters in the harbour and the occasional black bear at Mendenhall stick with children long after the trip.
Family-friendly excursions include the White Pass railway from Skagway (a 3-hour round trip in heated carriages), the Mendenhall Glacier shuttle and trail walk from Juneau, and the Saxman Native Village totem tour from Ketchikan. Kayak and zip-line operators usually set minimum ages around 8 to 10.
Onboard, Norwegian Bliss, Royal Caribbean’s Anthem of the Seas and Princess’s Discovery Princess have the largest kids facilities. Norwegian and Royal Caribbean run their kids clubs by age band from 3 to 17.
Cruisetours that add Denali work well for families with older children who can handle the longer travel days. For under-fives, stick with a 7-night round-trip from Seattle.
What else should you know before booking an Alaskan cruise?
Five points that change the booking call.
Glacier Bay matters. If seeing Glacier Bay is a priority, book Princess or Holland America. NCL, Royal Caribbean, Carnival and most others do not hold a permit and substitute Hubbard or Endicott Arm. Both are good but they are not Glacier Bay.
Round-trip versus one-way. A round-trip from Seattle is simpler logistically since you fly into and out of the same airport. A one-way Vancouver to Seward gives more time in Alaska and lines up with a Denali land tour, but you need two separate flight bookings.
Balcony cabin on the scenic-cruising day. The four to six-hour run past the glacier face is the moment you will want a private viewpoint. Public viewing decks fill up in July and August.
Book excursions early. White Pass railway, Mendenhall helicopter and Tracy Arm catamaran routinely sell out for July sailings before April.
Take out travel insurance with cruise cover. Standard policies often exclude shore-side rebooking if the ship has to skip a port due to weather, which happens occasionally on the Gulf of Alaska crossing. Ask the underwriter directly.
