Alaska Cruises

An Alaska cruise is the opposite of a beach cruise. The destination is not the port — it is the view from the rail: mile-wide rivers of ice, fjords walled in spruce, humpbacks bubble-feeding beside the ship. Everything sails between May and September, everything books early, and everything rewards a little planning. Here is how the pieces fit.

Glacier Bay and the great ice

The centerpiece of most itineraries, Glacier Bay National Park admits only a limited number of ships per day, with park rangers boarding to narrate as tidewater glaciers calve apartment-sized icebergs into the sea. Princess and Holland America hold the most permits — a real factor when choosing a line. Ships that miss Glacier Bay substitute Hubbard Glacier, the longest tidewater glacier in North America, or the twin Sawyer Glaciers of Tracy Arm. Any of them will silence a deck full of people. Dress warm, get outside, and stay for the whole slow, thunderous show.

The Inside Passage — the sheltered highway

Between Vancouver Island and the Alaska Panhandle runs a thousand miles of protected channels — the Inside Passage. The ship threads forested islands so close you can hear waterfalls, past fishing boats, lighthouses and the occasional bear on a beach. It is calm water, which is why even nervous sailors love this route, and it strings together the port towns — Ketchikan, Juneau, Skagway — like beads. Vancouver departures sail the full Canadian passage; Seattle departures run outside Vancouver Island for part of the trip, a meaningful difference for scenery lovers.

Juneau — the capital you can only reach by water

No roads lead to Juneau. Alaska's capital spreads beneath Mount Roberts, a tram ride from the dock, and a short shuttle from the Mendenhall Glacier — the most accessible great ice in the state, with salmon streams and Nugget Falls beside it. From the same harbor: whale-watching boats with near-guaranteed humpback sightings in season, helicopter rides to dog-sled camps on the icefield, and king crab legs the size of your forearm. Juneau is usually the longest port day of the cruise, and it earns it.

Whales, eagles and bears

Alaska cruises are wildlife cruises whether you plan them that way or not. Humpbacks feed in the channels all summer — watch for the bubble-net feeding frenzies near Juneau. Orcas patrol the same water, bald eagles sit on the channel markers like traffic cops, and sea otters raft in the kelp. Shoreside, the salmon runs draw bears from July onward, and the best viewing is from the ship itself on scenic-cruising days. Bring binoculars — the cheapest upgrade in all of cruising — and keep a layer on: the rail is where everyone ends up, whatever the itinerary promised.

Big ship or small ship?

The mainstream choice is a big, comfortable resort ship: better prices, more dining, kids' programs, and viewing lounges designed for glacier day. Step down in size and the calculus changes — expedition-style ships carry a few hundred guests, land by Zodiac, and reach coves the big hulls pass by, at several times the per-day price. Between them sit the premium lines' mid-size ships, the traditional Alaska specialists with the best naturalist programs. None is wrong; match the ship to whether your trip is about the scenery alone or the ship as well. Our first-timer guide helps you weigh it.

The frontier ports: Ketchikan, Skagway, Sitka

Ketchikan, the salmon capital, stacks its colorful Creek Street boardwalk over the water and offers the state's best native totem collections — and some of its heaviest rain, so dress for it and go anyway. Skagway is a gold-rush film set that happens to be real, gateway to the White Pass & Yukon railway climbing the same gorge the stampeders died on. Sitka, the old Russian capital, mixes Orthodox onion domes with raptor centers and the wildest setting of the three. Each port sells excursions hard; each also rewards a simple walk with a map. Save the helicopter money for Juneau.

Season strategy. May and September sailings can cost two-thirds of July's for the same ship. Whale activity peaks June to August; bears follow the salmon from July; northern lights become possible on late-September departures. Book popular one-way and Glacier Bay itineraries close to a year out.
