A day in Glacier Bay National Park is often the undisputed highlight of an Alaska cruise. Spanning 3.3 million acres of remote UNESCO World Heritage wilderness, this is not a typical port of call. There are no t-shirt shops, no diamond stores, and no crowded bus tours. Instead, you are treated to 8 to 10 hours of uninterrupted, breathtaking nature.
Just 250 years ago, this entire bay was buried under a single massive river of ice. Today, it represents one of the fastest glacial retreats on record, leaving behind deep fjords, towering mountains, and several active tidewater glaciers. Because access is strictly limited by the National Park Service, only a select few cruise lines—primarily Princess, Holland America, Celebrity, and Carnival—hold the coveted permits to bring you here.
Here is exactly how to maximize your scenic cruising day in Glacier Bay.
Getting Off the Ship
You don’t. For the vast majority of Alaska cruisers, Glacier Bay is a purely scenic cruising day. The ship acts as your floating visitor center, and no passengers disembark.
Instead of you getting off the ship, the destination comes to you. Around 6:00 AM, as your ship enters the mouth of the bay near Bartlett Cove, it will slow down to meet a small National Park Service pilot boat. Park Rangers will safely transfer onto the moving cruise ship. Within 15 minutes of boarding, they will take over the ship’s public address system and begin broadcasting expert commentary about the landscape, history, and wildlife directly to the open decks and stateroom TVs.
The rangers also set up a makeshift visitor center in one of the ship’s main observation lounges. If you have a National Park Passport, head there early in the morning to get your official Glacier Bay stamp.
What to Do in Glacier Bay
Since you are confined to the ship, your day is all about observation. Here is how to prioritize your time on board.
1. Watch the Glaciers Calve at the Head of the Bay After a few hours of sailing, your ship will reach the active tidewater glaciers at the end of the fjords. The most famous is Margerie Glacier, a dramatic, 21-mile-long river of ice that drops 250 feet directly into the ocean. The ship will idle here for roughly an hour, rotating slowly so both sides get a view. Stand on the open decks to watch and listen for “calving”—massive columns of ice breaking off and crashing into the sea.
2. Spot Johns Hopkins and Grand Pacific Glaciers Depending on the specific routing and the time of year (Johns Hopkins Inlet is sometimes closed in early summer to protect harbor seal pups), you will also view other monumental ice flows. Grand Pacific Glacier is massive but is covered in a thick layer of rock and debris, making it look almost like a muddy mountain.
3. Scan for Wildlife Wildlife viewing in Glacier Bay is spectacular but requires patience and the right gear. Keep your binoculars glued to your eyes. In the water, look for humpback whales, orcas, harbor porpoises, and rafts of sea otters floating on chunks of glacier ice. Scan the shorelines for brown and black bears flipping over rocks, and check the steep, rocky cliffs for white specks that turn out to be mountain goats.
4. Attend the Ranger Presentations The Park Rangers don’t just talk over the intercom. They usually host a massive visual presentation in the ship’s main theater during the afternoon sail-out, detailing the history of the native Huna Tlingit people and the rapid glacial retreat of the area.
Shore Excursions Worth Booking
Because you do not dock, traditional shore excursions do not exist for most cruisers in Glacier Bay. However, there are two exceptions where you might spend money to enhance your day:
- Shipboard Sanctuary/Cabana Passes ($50 - $100): If your ship features a private, adults-only outdoor retreat (like the Sanctuary on Princess Cruises), booking a pass for Glacier Bay day is highly recommended. You get plush loungers, provided blankets, dedicated bar service, and uncrowded panoramic views. These passes sell out on embarkation day, so book immediately.
- Gustavus Small-Boat Excursions ($150 - $250): A tiny fraction of small expedition ships (like UnCruise) or specific itineraries actually stop at Gustavus—the tiny town at the bay’s entrance. If your itinerary explicitly lists Gustavus, book the Glacier Bay Day Tour via the park lodge. It puts you on a high-speed catamaran that gets much closer to the shoreline and wildlife than a 3,000-passenger mega-ship ever could.
What to Skip
- Sleeping In: The ship enters the bay early, usually around 6:00 AM. The entrance near the forested islands of the lower bay is prime whale-watching territory. If you sleep until 9:00 AM, you’ve missed a third of the park.
- The Balcony Trap: It is tempting to stay in your bathrobe on your private balcony. Don’t. Your balcony only shows you 50% of the scenery. The best viewing points are the ship’s bow, the top outdoor decks, or the helipad (which many ships open specifically for this day). You want a 360-degree view to spot wildlife.
Eating in Glacier Bay
Dining on Glacier Bay day is unique because no one wants to sit inside a dining room and miss the scenery. Cruise lines know this and bring the food to the decks.
- Dutch Pea Soup: If you are sailing on Holland America Line, it is a cherished tradition for the crew to serve steaming mugs of traditional Dutch split pea soup on the open decks as you approach the glaciers. It is free, warming, and delicious.
- Deck Barbecues: Many cruise lines (including Princess) will host an outdoor barbecue near the main pool deck for lunch, serving grilled salmon, bratwurst, and hot chili so you don’t have to go inside to the buffet.
- Spiked Hot Drinks ($10 - $15): Waiters will heavily circulate the viewing decks with carts selling hot chocolate spiked with Baileys, Peppermint Schnapps, or Kahlúa.
Practical Info
Weather & What to Wear Expect it to be cold. Even if it is a beautiful 70°F sunny day in Juneau the day before, the ambient temperature drops significantly as you sail into a fjord packed with millions of tons of ice. The temperature on the open decks hovers around 50-55°F in July. Wind chill off the bow makes it feel colder. Dress in warm layers and wear a windproof rain jacket. A warm hat and gloves are mandatory.
Gear to Bring Do not rely on your smartphone to photograph Glacier Bay. You need a dedicated camera with a zoom lens (at least 300mm to 600mm) to properly capture bears on the shoreline or the intricate blue details of the ice. Furthermore, binoculars are absolutely essential. A pair of 10x42 binoculars (typically costing $150 to $300) is the sweet spot for magnification and stability on a moving ship. Without them, the bears and mountain goats will just look like blurry dots.

Frequently Asked Questions
Which cruise lines go to Glacier Bay National Park?
Only licensed vessels with limited permits are legally allowed to enter the bay, meaning not all Alaska cruises go here. Princess and Holland America hold the majority of the permits, while Celebrity, Carnival, and Norwegian have limited access. When booking your itinerary, you must explicitly check that Glacier Bay is listed, as ships without a permit will visit Endicott Arm or Hubbard Glacier instead.
Can you get off the ship in Glacier Bay?
For 99% of large cruise ship passengers, you do not get off the ship in Glacier Bay. It is a scenic cruising day where the ship slowly navigates the 3.3 million acres of UNESCO World Heritage wilderness. The ship effectively becomes your mobile viewing platform for the 8-10 hours you spend inside the park boundaries.
What is the best side of the ship for Glacier Bay?
There is no 'best' side of the ship, because the captain will rotate the vessel 360 degrees when you reach the major tidewater glaciers like Margerie. If you have a balcony, you will get a great view for about 30 to 45 minutes before the ship slowly spins to give the other side a turn. However, the absolute best views are from the open upper decks or the bow, where you have an unobstructed, panoramic vantage point.
Will we see glaciers calving in Glacier Bay?
Yes, there is a very high probability you will see calving events, especially at Margerie Glacier. Calving is when massive chunks of ice break off the glacier face and crash into the water below, creating a thunderous roar known as 'white thunder.' For the best chance to see and hear this, head to the open decks, stay quiet, and keep your camera ready—by the time you hear the crack, the ice is already falling.
What should I wear for a day in Glacier Bay?
You need to dress in warm, windproof layers, as the temperature on the open decks rarely exceeds 50-55°F, even in July. Start with a moisture-wicking base layer, add a heavy fleece or down sweater, and top it with a waterproof and windproof shell. Do not forget a warm beanie, gloves, and thick wool socks, as standing still on a breezy metal deck will chill you much faster than walking in port.
Do National Park Rangers board the ship in Glacier Bay?
Yes, National Park Service rangers board the moving cruise ship via a small pilot boat near the entrance to the bay around 6:00 AM. They set up a mobile visitor center in one of the lounges, stamp National Park passports, and broadcast expert commentary over the ship's public address system all day. They also have a dedicated desk where you can buy books, ask questions, and get junior ranger badges for kids.
What wildlife can you see in Glacier Bay?
Glacier Bay is incredibly rich in marine and terrestrial wildlife, but you need binoculars to see most of it. Look for humpback whales, orcas, and harbor porpoises in the water, as well as Steller sea lions and sea otters resting on ice floes. On land, use your binoculars to scan the steep cliffs for mountain goats, look for brown and black bears foraging on the shorelines, and watch the skies for tufted puffins.
Is a balcony cabin worth the extra cost for Glacier Bay?
A balcony is heavily recommended for an Alaska cruise, and Glacier Bay is a prime reason why, as it allows you to view the scenery in private with a cup of hot coffee. Balconies typically cost $500 to $1,000 more per person than oceanview or interior cabins. However, if you are on a budget, an interior room is perfectly fine as long as you commit to spending the day on the public open decks, which actually offer better, wider views anyway.
