Alaska Cruise Deals: What to Know Before You Book

Alaska is unlike any other cruise region. You see glaciers up close. You spot whales, bears, and eagles from the deck. You sail through some of the most sheltered, scenic water anywhere in the world.

This guide covers the two main types of Alaska cruise. It also covers the best ports and the best time to go. And it covers what to check before you book.

Inside Passage vs. Gulf of Alaska: Know the Difference

Most Alaska cruises fall into one of two route types. Inside Passage cruises are round trip. They leave from Seattle or Vancouver, sail north, then return along the same sheltered waterway. The water stays calm since the route runs between islands and the mainland. This makes it a solid pick for first-time Alaska cruisers.

Gulf of Alaska cruises run one-way, usually between Vancouver and Whittier or Seward. These routes reach different glaciers, like Hubbard Glacier and College Fjord, that the Inside Passage does not visit. Whittier and Seward both serve as gateways to Anchorage. Browse current Alaska routes and departure ports to see which style fits your trip.

The Ports Most Cruises Visit

Juneau, Ketchikan, and Skagway show up on almost every Inside Passage itinerary. Juneau is Alaska’s capital and a strong base for whale watching and glacier tours. Ketchikan is known for its rainforest and native culture. Skagway carries real gold rush history, with old buildings and train rides into the mountains.

Many sailings also add a stop at Icy Strait Point. Others add a scenic cruise through Glacier Bay National Park or Tracy Arm Fjord. Not every itinerary includes Glacier Bay, since entry is limited. Check your specific route closely if seeing this park is a priority. Compare itineraries that include Glacier Bay before you book.

Wildlife and Scenery

Alaska cruises offer some of the best wildlife viewing at sea. Humpback whales, sea otters, harbor seals, and bald eagles are common sights from the deck. On shore, keep an eye out for brown bears and moose. Tidewater glaciers, where ice meets the ocean directly, are one of the trip’s biggest highlights.

The Best Time to Cruise to Alaska

The season runs from April through early October. April is quiet, with cooler mornings and fewer ships in port. May and June mark the start of the busy season, with long daylight hours and returning humpback whales. July and August bring the warmest weather and the most active wildlife and glacier viewing, along with the biggest crowds.

Land-and-sea cruisetours are also common on this route. These pair the cruise with rail travel and time near Denali National Park. Check current cruisetour and land package options if you want to add Denali to your trip.

Where These Cruises Leave From

Seattle and Vancouver are the two main departure ports for round-trip Inside Passage sailings. Seattle departures add a scenic day sailing through Puget Sound that Vancouver departures skip. One-way Gulf of Alaska sailings typically start or end in Vancouver, Whittier, or Seward.

Tips Before You Book

Book six to twelve months ahead for the best choice

Popular sailing dates can sell out well in advance. So can Glacier Bay itineraries and cruisetours. Book early if you have specific dates or ports in mind.

Decide between Inside Passage and Gulf of Alaska early

These two route types see different glaciers and different ports. Pick the type first, then compare ships and lines within that route.

Pack layers no matter what month you sail

Alaska weather can shift fast, even in summer. Bring a warm layer and a waterproof jacket for days on deck.
