Alaska Cruise Complete Guide: Glacier Bay, Inside Passage & Northern Lights 2025
Alaska — the largest US state — is home to North America’s tallest peaks, most expansive glaciers, and most untamed wilderness. For outdoor adventurers and travelers seeking a truly extraordinary natural experience, it belongs on every bucket list. Exploring Alaska by cruise ship is the ideal way to balance comfort with adventure.
Why Choose an Alaska Cruise
💡 Shore excursions: Book shore excursions on Klook to save 20–30% versus onboard ship pricing, with free cancellation.
Alaska’s vast terrain means many of its most spectacular sights are accessible only by boat or plane. A cruise lets you glide through breathtaking Glacier Bay from the comfort of your cabin — while still stopping at charming port towns for rich shore excursions.
Why cruise Alaska:
- No long drives — you rest and travel simultaneously
- A floating observation deck with 360° views of fjords and glaciers
- Onboard entertainment for the whole family
- Multiple Alaska highlights in a single trip
Main Cruise Routes
Route 1: Inside Passage
The most classic Alaska cruise route — departing Seattle or Vancouver, hugging the Canadian and Alaskan coastline through sheltered island passages, and ending at Juneau, Alaska’s state capital.
Key port stops:
- Ketchikan: The salmon capital of the world, rich in Native American cultural heritage
- Juneau: The state capital, where you can take a helicopter onto a glacier
- Skagway: A historic gold-rush town with a dramatic narrow-gauge railway through White Pass
Route 2: Glacier Bay
This route goes directly to Glacier Bay National Park for up-close views of ice calving into the sea. The park has multiple active glaciers — Margerie and Johns Hopkins are the most spectacular.
Route 3: Round-Trip
If you’d rather not fly to the West Coast, round-trip sailings from Vancouver or Seattle are perfect for time-crunched travelers who still want the Alaska experience.

Don’t forget:
