Alaska Cruise Glaciers Compared: Glacier Bay, Hubbard, Dawes, and More
Glacier Bay vs. Hubbard Glacier is the comparison I get asked about most when people pick an Alaska itinerary, and both are excellent. Glacier Bay is a full day inside a national park with rangers on board and several tidewater glaciers. Hubbard Glacier is a single, enormous wall of ice that Princess calls Alaska's largest tidewater glacier.
If I could pick only one, I would take Glacier Bay for the variety and the ranger program, and I would add Hubbard whenever a one-way Gulf of Alaska itinerary makes it possible to get both. Dawes Glacier and College Fjord round out the list, and Tracy Arm comes with a big asterisk after the 2025 landslide.
Alaska Cruise Glaciers at a Glance
| Glacier day | Where | Which cruises |
| Glacier Bay National Park | West of Juneau, near Icy Strait | Only the seven companies holding park contracts |
| Hubbard Glacier | Disenchantment Bay, near Yakutat | Mostly one-way Gulf of Alaska sailings and some roundtrips |
| Dawes Glacier | Head of Endicott Arm, south of Juneau | Inside Passage roundtrips on many lines |
| College Fjord | Prince William Sound, near Whittier | One-way sailings to or from Whittier |
| Tracy Arm | North of Endicott Arm, south of Juneau | Several major lines skipped it in 2026 |

Glacier Bay National Park on a Cruise
Glacier Bay National Park is a UNESCO World Heritage Site with seven tidewater glaciers, according to Princess. The National Park Service says cruise ships typically spend a full day, about 9 to 10 hours, in the bay, including a stop at a major tidewater glacier. Park rangers board each ship to narrate, give talks, run Junior Ranger activities, and staff an information desk.
The usual turnaround point is Margerie Glacier at the northern end of Tarr Inlet. The Park Service describes it as about 21 miles long, starting in the Fairweather Range above 9,000 feet, and moving roughly 6 feet a day. That speed is why it is a dependable spot for calving. Late in the season, ships can also enter Johns Hopkins Inlet, which the Park Service closes to cruise ships earlier in the summer to protect harbor seals.
The catch is access. Only ships run by companies holding a National Park Service concession contract can enter. The current ten-year contracts, effective October 1, 2019, went to Princess, Holland America, Norwegian, Cunard, Seabourn, Viking, and Royal Caribbean Cruises Ltd. Princess alone schedules 85 Glacier Bay calls in 2027, and Holland America says Glacier Bay is standard on its Alaska cruises. Holding a contract does not mean every sailing goes in, so read the day-by-day itinerary before you book.
Hubbard Glacier on a Cruise
Hubbard Glacier sits at the head of Disenchantment Bay near Yakutat. Princess calls it Alaska's largest tidewater glacier and points to how fast it moves and how often it calves. It also behaves differently from most Alaska glaciers. The U.S. Geological Survey has documented Hubbard growing and advancing, and twice, in 1986 and 2002, it pushed far enough to temporarily dam Russell Fjord behind it.
A Hubbard day is shorter and more focused than Glacier Bay: the ship sails up Disenchantment Bay, holds position in front of the face, and turns around. There is no ranger program, and you see one glacier instead of several. What you get is scale. The face stretches across the bay in a way that is hard to judge until a calving chunk hits the water.
Ice in the bay controls how close a ship can get, so the captain decides on the day. Because Hubbard sits in the open Gulf, it shows up mostly on one-way sailings between Vancouver and the Anchorage-area ports, plus some longer roundtrips. My Inside Passage vs. Gulf of Alaska comparison explains how route choice decides whether Hubbard is even possible.
Glacier Bay vs. Hubbard Glacier: Which Is Better
Here is how I break the tie between the two biggest names.
- Variety: Glacier Bay wins. You spend most of a day in the park and pass several glaciers, mountains, and wildlife habitat.
- Single wow moment: Hubbard wins. One massive, active face is hard to beat if calving is the goal.
- Learning: Glacier Bay wins with National Park Service rangers on board.
- Availability: Glacier Bay is limited to permit-holding lines. Hubbard is open to any line whose route reaches it.
- Route fit: Glacier Bay works on roundtrips. Hubbard mostly needs a Gulf of Alaska sailing.
The best answer is both. Princess builds two glacier-viewing days into its 7-day Voyage of the Glaciers between Vancouver and Whittier, choosing from Glacier Bay, Hubbard, and College Fjord depending on the sailing. You can see dates on current Princess Cruises offers, and my best Princess Alaska cruises post covers which itineraries I prefer.
Dawes Glacier in Endicott Arm
Dawes Glacier sits at the end of Endicott Arm, which Princess describes as a narrow fjord over thirty miles long. The trip in is half the attraction: steep cliffs, waterfalls, and floating ice for most of the morning before the ship reaches the face. Narrow water and ice can stop larger ships short of the glacier, so this day comes with less certainty than Glacier Bay.
Endicott Arm became more important in 2026. After the Tracy Arm landslide, Carnival, Holland America, and Royal Caribbean said they would sail to Endicott Arm and Dawes Glacier instead. My full Dawes Glacier and Endicott Arm cruise guide covers what to expect on deck.
College Fjord in Prince William Sound
College Fjord is the one most first-timers have never heard of. Members of the 1899 Harriman Expedition, including John Muir, named its glaciers after East Coast colleges: Harvard, Yale, Amherst, Barnard, Bryn Mawr, Smith, and Vassar. Princess notes five glaciers visible in a row, and calls Harvard Glacier Alaska's second-largest tidewater glacier, with a face about 1.5 miles wide reaching back 24 miles to the Chugach Icefield.
Because it sits close to Whittier, College Fjord appears mainly on one-way sailings that start or end there. It pairs naturally with a Denali land tour, which I cover in Alaska cruisetours explained.
Tracy Arm After the 2025 Landslide
Tracy Arm, home of the twin Sawyer Glaciers, was one of the most popular scenic cruising days in Alaska. On August 10, 2025, a massive landslide triggered a tsunami inside the fjord. For 2026, Carnival, Holland America, and Royal Caribbean announced they would skip Tracy Arm, and Royal Caribbean said conditions were not suitable for cruise ship navigation.
Some 2027 itineraries released before the landslide still list Tracy Arm. If yours does, I would plan on Endicott Arm as the likely substitute and treat Tracy Arm as a bonus if it returns.
Pro Tip: On any glacier day, dress for wind on the open deck even if the forecast looks mild, and go out early. The best rail spots at the bow fill fast once the ship nears the face. My Alaska cruise packing list covers layers by month.
Mendenhall Glacier and Other Alaska Glaciers From Port
You can also see glaciers on land. Mendenhall Glacier outside Juneau has a visitor center open daily during the season, and helicopter tours land on icefields above the city. You can compare Mendenhall and icefield tours on Viator, and my best Juneau cruise excursions post explains which ones are worth the money. Skagway's railway climbs past glaciated peaks as well, covered in the best Skagway excursions.
Which Alaska Cruise Glacier Day Should You Pick
For a first Alaska cruise on a roundtrip, I would choose a sailing with Glacier Bay. For a once-in-a-lifetime trip, I would book a Gulf of Alaska one-way that pairs Glacier Bay with Hubbard or College Fjord. Dawes Glacier is a strong day on its own, especially on lines without Glacier Bay access. When I match a glacier day to an itinerary as your travel agent, I check the day-by-day schedule for each sailing, since two cruises on the same ship a week apart can visit different glaciers.
Timing plays a part too. My best time to cruise Alaska post covers how daylight and weather change across the season.
Glacier Bay vs. Hubbard Glacier: Frequently Asked Questions
Is Glacier Bay or Hubbard Glacier better? Glacier Bay gives you a full day, several glaciers, and park rangers. Hubbard gives you one huge, very active glacier. I rank Glacier Bay first and add Hubbard when the route allows.
Which cruise lines go into Glacier Bay? The current National Park Service contracts went to Princess, Holland America, Norwegian, Cunard, Seabourn, Viking, and Royal Caribbean Cruises Ltd. Check your specific sailing, since not every departure goes in.
Can a cruise get close to Hubbard Glacier? It depends on ice in Disenchantment Bay. The captain decides on the day how close the ship can safely go.
Is Tracy Arm open to cruise ships in 2027? That was not settled as of October 2026. Several major lines skipped it in 2026 after the August 2025 landslide and sent ships to Endicott Arm and Dawes Glacier instead.
Which Alaska cruise sees the most glaciers? One-way Gulf of Alaska sailings, such as Princess's Voyage of the Glaciers with two glacier-viewing days, usually see the most.
Book an Alaska Cruise With the Right Glacier Day
My pricing is the same as booking direct, and I can often add group rates or promotions that are not on the cruise line's website. You also get a person to call if an itinerary changes, which happens more in Alaska than people expect. Send me your dates, and I will shortlist sailings by the glacier day you want most.
