Selecting the right glacier viewing experience is a primary consideration for many travelers booking an Alaska cruise. While itineraries exist that visit both locations, most passengers must choose between Hubbard Glacier and Glacier Bay National Park and Preserve. Experts suggest that while it is possible to enjoy an Alaskan voyage without seeing ice, those prioritizing glaciers should book midseason cruises with multiple glacier days or add specific excursions to mitigate risks posed by weather, water ice, or onboard emergencies.
Hubbard Glacier stands out as the longest tidewater glacier in North America, featuring a face exceeding 400 feet in height and spanning nearly seven miles wide. Located within the Wrangell-St. Elias National Park and Preserve, this UNESCO World Heritage Site is often nicknamed "The Galloping Glacier" due to its century-long advance into Disenchantment Bay. This movement results in dramatic calving events where ice chunks the size of three-story buildings crash into the sea, creating thunderous roars and waves. Ships typically approach within a quarter to half-mile of the glacier face, though heavy ice can sometimes force vessels to halt further out. Most major cruise lines include Hubbard on one-way or longer itineraries, with only a select few offering it on seven-night round-trip voyages.
In contrast, Glacier Bay National Park and Preserve covers over three million acres and contains more than 1,000 glaciers, seven of which are tidewater glaciers visible from the ship. A key advantage of Glacier Bay is the extended duration of the visit, with ships spending nine to 10 hours traveling over 120 miles within the park. During this time, park rangers board the vessel to provide educational commentary, maps, and even stamp national park passports. The park limits access to only two large cruise ships per day, though smaller vessels are classified differently and face fewer restrictions. This extended stay increases opportunities for wildlife sightings, including harbor seals, Steller sea lions, sea otters, brown bears, humpback whales, and orcas.
When comparing the two destinations, Glacier Bay offers a longer scenic cruising experience and higher odds of viewing multiple glaciers, making it more likely to succeed even in less-than-ideal weather. Hubbard Glacier, however, provides a more dramatic presentation with its massive size, brilliant blue colors, and frequent calving activity. For families or travelers with shorter attention spans, the briefer visit to Hubbard may be preferable, whereas Glacier Bay requires patience and warm clothing for an all-day excursion. In terms of cruise line availability, Hubbard is accessible via 16 different lines, while Glacier Bay offers a superior selection of small-ship options. Cost-wise, Glacier Bay holds a slight edge as it appears on some seven-night round-trip itineraries, whereas optimal viewing at Hubbard often requires additional shore excursions on smaller boats.
