Alaska by Cruise Ship: The Most Spectacular Voyage You Will Ever Take

My mother-in-law called me after her Alaska cruise and said, "Erin, I've been to 40 countries. Alaska is the most beautiful place I've ever seen." She's not alone. I hear some version of that statement from nearly every client who sails Alaska.

There is something about Alaska that defies description — the scale of the glaciers, the silence of the wilderness, the wildlife appearing around every corner. It's a destination that humbles you, and I mean that in the best possible way.

Here's everything you need to know to plan the perfect Alaska cruise.

Why a Cruise Is the Best Way to See Alaska

Alaska's most spectacular scenery is accessible by water. The Inside Passage — the network of waterways, islands, and fjords that runs along the southeastern Alaska coast — is simply not reachable by road. A cruise ship is your floating hotel, your transportation, and your viewing platform all in one.

Waking up to a glacier filling your cabin window. Watching humpback whales breach from your balcony. Sailing through a fjord so narrow the mountains seem close enough to touch. These are experiences you simply cannot have any other way.

The Two Main Itinerary Types

Inside Passage (Round-trip from Seattle or Vancouver) — This is the classic Alaska cruise. You sail north through the Inside Passage, stopping at ports like Ketchikan, Juneau, Skagway, and Sitka, then return south. It's typically 7 nights and is perfect for first-time Alaska cruisers.

Gulf of Alaska (One-way, Seward to Vancouver or vice versa) — This itinerary takes you further north, crossing the Gulf of Alaska and visiting Hubbard Glacier or Glacier Bay. It's more dramatic and covers more ground, but requires a one-way flight. I recommend this for repeat Alaska visitors or those who want the most spectacular scenery.

The Best Ports

Juneau — Alaska's capital city is accessible only by sea or air (no roads connect it to the rest of Alaska). The Mendenhall Glacier is right in town, and whale watching here is exceptional. Don't miss the Mount Roberts Tramway for panoramic views.

Ketchikan — The "Salmon Capital of the World" and home to the world's largest collection of standing totem poles. The Creek Street boardwalk is charming, and the Misty Fjords National Monument is one of the most dramatic landscapes in Alaska.

Skagway — A perfectly preserved Gold Rush town that feels like stepping back in time. The White Pass & Yukon Route railway is one of the most scenic train rides in North America.

Sitka — My personal favorite port. Sitka has a fascinating Russian history, incredible wildlife (sea otters, bald eagles, sea lions), and the Sitka National Historical Park is stunning.

Glacier Bay National Park — Not a port, but a highlight of many itineraries. Sailing into Glacier Bay and watching the glaciers calve is one of the most awe-inspiring experiences in travel.

Wildlife: What to Expect

Alaska's wildlife viewing is extraordinary. On a typical cruise, you can expect to see:

• Humpback whales — Almost guaranteed in Southeast Alaska, especially near Juneau
• Orca (killer whales) — Less common but unforgettable when spotted
• Brown and black bears — Best seen on shore excursions
• Bald eagles — Everywhere. Seriously, everywhere.
• Sea otters — Floating on their backs, cracking shellfish. Adorable.
• Dall's porpoises — Often ride the bow wave of the ship
• Sitka black-tailed deer — Common in Southeast Alaska

My Top Shore Excursions

Whale watching in Juneau — Book with a reputable local operator. Sightings are nearly guaranteed May through September.

Mendenhall Glacier hike — Walk right up to the face of a glacier. Combine with a kayak tour for the full experience.

White Pass & Yukon Route Railway (Skagway) — A narrow-gauge railway that climbs 2,900 feet in 20 miles. The views are staggering.

Misty Fjords floatplane tour (Ketchikan) — See the fjords from the air. One of the most spectacular things I've ever done.

Bear watching (various ports) — Float plane or boat tours to remote areas where brown bears fish for salmon. Absolutely incredible.

What to Pack for Alaska

Alaska weather is unpredictable, even in summer. The key is layers.

• Waterproof jacket — Essential. It will rain.
• Fleece or down mid-layer — Temperatures can drop quickly, especially near glaciers
• Waterproof pants — For excursions
• Waterproof hiking boots — For any shore excursion involving walking
• Gloves and a hat — Even in July, you'll want them near glaciers
• Binoculars — Non-negotiable for wildlife viewing
• Camera with a good zoom lens — You'll want to capture wildlife from a distance

The Best Time to Cruise Alaska

May through September is Alaska cruise season. My sweet spots:

Late May/Early June — Fewer crowds, lower prices, and the landscape is lush and green after winter. Whale watching is excellent.

July — Peak season with the best weather and longest days. Book early and expect higher prices.

August/Early September — Salmon runs are in full swing, bears are actively fishing, and the fall colors are beginning. A beautiful time to visit.

One Thing Nobody Tells You

Bring sea sickness medication even if you've never been seasick. The Inside Passage is generally calm, but the Gulf of Alaska crossing can be rough. Better to have it and not need it.

Alaska will change you. I promise.
