Columbia Glacier Cruise

Six hours sounds excessive for a bay you can see on a map in one glance. It is not, and understanding why is the difference between an impatient afternoon and one of the better days of an Alaska trip.

The crossing is half the tour

Columbia Bay is west of Valdez across open Prince William Sound, and the boat does not run straight there. It stops. It stops for rafts of sea otters lying on their backs in the kelp, for harbour seals hauled out on ice, for Steller sea lions on the rocks, for Dall’s porpoise riding the bow wave, and — several times a season — for humpbacks and orca. Bald eagles are constant. Puffins turn up.

None of that is guaranteed on any single crossing, and a crew that promised it would be lying. What is guaranteed is that the boat is built to loiter: an enclosed heated cabin so you can warm up between sightings, open decks so you can be outside for the ones that matter, seating, toilets, and a galley that puts hot soup in front of you somewhere around the halfway mark.

Then the temperature drops

You know Columbia Bay has started before anyone announces it. Brash ice thickens around the hull, then bergy bits, then bergs the size of a house, blue where the air has been squeezed out of them over centuries. Seals sleep on the flat ones. The water goes still in the way that only ice-covered water does.

This is the point at which the layers you packed either exist or do not. The cabin is warm and the decks are where the experience is, and the gap between the two on an ice day is significant.

Why the glacier itself stays at a distance

Columbia Glacier has pulled back more than 12 miles since the early 1980s. What it left behind is a submerged terminal moraine across the mouth of the bay — the ridge of rock and gravel it built while it was still grounded there — and that moraine now traps the icebergs the glacier keeps producing. The bay is corked with its own ice.

So the captain works in as far as the ice, the tide and the wind allow on the day. Sometimes that is a long way and the terminus appears as a low white band with the Chugach stacked behind it. Sometimes the field is where you stop. Neither is a failed tour; both are the same story told at different distances. If a live calving face is specifically what you want, the honest answer is the Meares Glacier cruise, which runs north to an advancing glacier with no berg field in the way — and which the crews themselves recommend when Columbia Bay is heavy.

Who this is the right trip for

Almost everyone. It is the trip for families, for mixed-mobility groups, for anyone who wants to be warm between sightings, and for anyone with exactly one day in Valdez. The only physical element is the ramp down to the dock, which is steep at low tide and where the crew will help if you ask at check-in.

If you want the ice at arm’s length instead of at rail’s length, the nine-hour sea kayak day puts you inside the berg field at sea level. It costs more than twice as much, takes half again as long, and is a genuinely different experience — we compare them properly in cruise vs kayak.
