Cruising Alaska: what to know

Alaska is the cruise where the scenery does the work. You're not here for the beach or the nightlife — you're here to watch glaciers calve, whales surface, and mountains slide past the rail for a week. It suits first-timers and seasoned cruisers alike, and it rewards a little planning.

When to go

The season runs May through September. The shoulder months (May and September) bring lower fares, fewer crowds, and a decent chance of clear, crisp days — though May is drier and September wetter. June through August is peak: the longest daylight, the warmest weather, the best wildlife viewing, and the highest prices. There's no bad month; there's a trade-off between cost and crowds.

Two kinds of itinerary

• Inside Passage, round-trip — usually from Seattle or Vancouver, sailing the sheltered waters among the islands and back. The simplest to book (fly in and out of one city) and the calmest sailing.
• Gulf of Alaska, one-way — between Vancouver and Seward or Whittier (for Anchorage), sailing farther north. This is the one to pair with a cruisetour — a land extension to Denali and the interior — if you want to see Alaska beyond the coast. It needs two different flights, so plan the logistics.

The ports

Most sailings stop at some mix of Juneau (whale-watching and the Mendenhall Glacier), Ketchikan (totem poles and salmon), and Skagway (the White Pass railway and gold-rush history). The highlight is often a day of glacier viewing — Glacier Bay, Hubbard, or Tracy Arm — where the ship simply holds position while the ice does the show. Check whether your sailing includes Glacier Bay; it's limited by permit and not every ship gets in.

What to pack and book

Dress in layers — it can swing from cool and wet to bright and warm in a day — with a waterproof outer layer and comfortable walking shoes. Excursions here are worth booking ahead; the best whale-watching and flightseeing trips sell out. And this is the itinerary where a balcony earns its price: the scenery passes all day, and you'll want to step outside for it without hunting for deck space.

A note from the desk

Alaska has more genuinely different ways to do it than most destinations — round-trip or one-way, with or without a land tour, peak or shoulder — and the right answer depends on your time and budget. Ask an advisor with your dates and we'll lay out the options that fit.
