Glacier Bay National Park: Quintessential Alaska

Glacier Bay National Park isn't a typical cruise stop. There are no cruise terminals or shore excursions. Instead, the ship spends an entire day gliding through 3.3 million acres of dynamic fjords, temperate rainforest, and active tidewater glaciers. To preserve the ecosystem and visitor experience, the National Park Service limits access to no more than two large cruise ships per day.

A day of scenic cruising in Glacier Bay National Park may look like:

Early Morning: Once in Glacier Bay, a small park tender boat pulls alongside your ship to drop off a team of National Park Service rangers and/or cultural liaisons. For the rest of the day, rangers provide live commentary over the ship's PA system, set up information desks, stamp National Park passports, and host programs for junior rangers.

Mid-Day: As the ship reaches the head of Tarr Inlet, the landscape transitions into sheer rock and deep-blue ice. The highlight for most vessels is Margerie Glacier, a wall of ice over a mile wide that rises more than 200 feet above the water line. Ships spend roughly an hour idling here, perhaps executing a slow, 360-degree rotation so guests on both port and starboard sides get equal, uninterrupted views.

Late Afternoon: The ship traces back down the bay, passing iconic rock formations like Gloomy Knob and the bird rookeries of South Marble Island before dropping the rangers off at the park boundary.

What to Look and Listen For

White Thunder: Before you see calving happen, you will often hear it. Ice under immense pressure groans and cracks with an acoustic boom resembling rolling thunder or cannon fire before crashing into the fjord.

Wildlife Hotspots: Keep binoculars glued to the shoreline. Sea otters often float in kelp beds near the entrance, Steller sea lions and tufted puffins sometimes cluster on South Marble Island, mountain goats can often be seen navigating the sheer cliffs of Gloomy Knob, and you may see a harbor seal resting on drifting icebergs ("bergy bits") near glacier faces.

Essential Cruising Tips

Don't stay pinned to your balcony: Having a private balcony is cozy, but it restricts your field of view to 180 degrees. Heading to the open upper decks or the covered wrap-around promenade deck allows you to switch sides rapidly when a humpback whale breaches or calving begins.

Pack dedicated rain gear and touchscreen gloves: Glacial wind rushing off millions of tons of ice drops ambient deck temperatures sharply. Pair a waterproof outer shell with wind-blocking fleece, and keep light gloves handy so your fingers don't freeze while holding a camera.

Tune in to the bridge broadcast: If your ship offers it, keep your stateroom TV set to the bow camera or open bridge channel while warming up inside so you don't miss ranger announcements about upcoming wildlife sightings.
