Everyone rushes back inside at Hubbard Glacier. That's the mistake.
We got within three quarters of a mile of Hubbard Glacier. The captain took us full port, then rotated the whole ship full starboard, so every cabin and every deck got a real view instead of half the ship staring at open water.
Then a piece of the face let go. Ice plunged into the bay and threw up a wave big enough to rock boats sitting a half mile back. Next to us, a chunk of ice had fresh blood on it. No idea what happened there, a seal or a sea lion probably, no remains anywhere around it. Just blood on ice, floating past a cruise ship.
That's Hubbard Glacier. And most people see about 10 minutes of it before they go back inside.
Why people leave too early
It gets cold. Colder than anywhere else on an Alaska cruise, because you're not just dealing with the air temperature, you're sitting a few hundred yards from a wall of ice that's actively dumping cold air off itself. My wife Sarah and my son Aiden felt it and went in after a while. Smart move, honestly.
But my daughter Addison and I stayed. The deck emptied out around us as people filed back inside for coffee and the buffet. And once the crowd thinned, it got quiet. Just the two of us, the brisk air, and this massive wall of ice calving every so often into the water in front of us.
That quiet is the part people miss. You don't get it in the first 10 minutes when everyone's out there with a phone up. You get it once most of the ship has given up and gone in.
What the glacier actually does while you're out there
Hubbard is nicknamed the Galloping Glacier for a reason. Unlike most glaciers right now, it's advancing, not retreating. Its face runs about 400 feet high and 6 miles wide, and it calves into Disenchantment Bay several times an hour. That's not a one-shot photo moment. That's an active, moving thing that keeps doing something new the longer you watch it.
A quarter mile is about as close as a ship can get on a good day. We were at three quarters of a mile, and that was still close enough to hear the ice groan before a piece let go, close enough to watch the wave roll out afterward. Ships don't get that view by luck. It takes a captain willing to work the ship, port to starboard, to give everyone a real angle instead of parking and calling it good.
How cold it actually gets
I couldn't give you an exact number. Somewhere in the 30s or below, and that's before you factor in the cold rolling straight off the ice. It was colder that day than any other day on our whole Alaska trip.
Bring real layers. Not a light jacket. A base layer, a warm mid layer, something that blocks wind, and gloves if you plan on staying out more than 20 minutes. Addison and I were out there a while, and the cold was worth it, but only because we were dressed for it.
When to actually go up on deck
Two strategies work here, and they're opposites.
Get up early and claim a good rail spot before the ship even reaches the glacier. You'll have the view locked in before the crowd shows up.
Or do what we did. Let the first wave of people go up, take their photos, get cold, and head back in. Then go up yourself. You lose a few minutes of the initial approach, but you get space, quiet, and as much time as you want without fighting for a rail spot.
What doesn't work is going up for 10 minutes, getting your photo, and leaving. You'll miss the calving. You'll miss the quiet. You'll miss the parts of this that actually stick with you.
Frequently asked questions
How close does a cruise ship get to Hubbard Glacier?
On a good day, ships can get within about a quarter mile of the face. We were at three quarters of a mile, which is still a strong, close view. Ice conditions in the bay determine how close the captain is willing to bring the ship.
How often does Hubbard Glacier calve?
Several times an hour. It's one of the more active glaciers you'll see on an Alaska cruise, partly because it's advancing rather than retreating.
How cold does it get on deck at Hubbard Glacier?
Expect temperatures in the 30s or lower, plus additional cold rolling off the ice itself. It's typically the coldest deck experience of an Alaska cruise.
How long should I plan to be on deck at Hubbard Glacier?
Longer than you think. The ship spends real time maneuvering for views, and the best moments, a calving event, a quiet stretch once the crowd clears, happen for people who stay out.
Is Hubbard Glacier worth seeing compared to other Alaska glaciers?
Yes. It's one of the most active glaciers on any Alaska itinerary, and its size and calving frequency make it a strong stop if your itinerary includes it.
