Bottom Line: The Inside Passage route (southbound from Seattle/Vancouver to Whittier/Anchorage) offers more reliable scenery — you’re protected by the coastal mountain range and see glaciers, whales and forests daily. The Gulf of Alaska route (one-way Vancouver to Whittier or vice versa) is wilder but riskier weather-wise, with potentially more dramatic whale sightings and the chance to see brown bears on remote islands.
An Alaska cruise is on virtually every North American traveler’s bucket list, and for good reason. The scale of the landscape — 16,000-foot peaks dropping directly into the sea, tidewater glaciers calving house-sized ice chunks, humpback whales breaching within arm’s reach of your balcony — is unlike anything accessible without weeks of wilderness expedition.
Route Comparison
Inside Passage (Round-trip Vancouver or Seattle)
The classic Alaska cruise experience. The Inside Passage is a coastal waterway protected by Vancouver Island and the Haida Gwaii archipelago, meaning calm seas almost every day — even in inclement weather.
Typical ports: Ketchikan → Juneau → Skagway → Icy Strait → Sitka (varies by cruise line)
Best for: First-time cruisers, families, anyone prone to seasickness
Gulf of Alaska (One-way: Vancouver ↔ Whittier/Anchorage)
One-way voyages that travel the open Gulf of Alaska, exposed to Pacific weather. More dramatic landscapes but higher risk of rough seas (especially in the shoulder seasons of May and September).
Typical ports: Sitka → Hubbard Glacier → Juneau → Skagway → Ketchikan (southbound); reversed northbound
Best for: Experienced cruisers seeking dramatic scenery, photographers chasing wildlife

Juneau — The State Capital
Juneau is only accessible by boat or plane — there are no roads into the city. The state legislature building is worth a quick visit (free tours), but the real draw is the Mendenhall Glacier, a 13-mile river of ice that terminates in a lake accessible by bus from the cruise terminal ($35 round-trip via Goldbelt’s tramway).
Whale watching: The channels around Juneau have exceptional humpback whale populations in summer. A 3-hour whale watching tour costs $120-150/person, but the guarantee of sightings (or partial refund) makes it worthwhile.
Skagway — The Gold Rush Town
Skagway is impossibly well-preserved for a gold rush town — the population was 30,000 during the 1898 Klondike Gold Rush, and today it’s 1,000. The White Pass & Yukon Route Railway is the star attraction, a narrow-gauge railway that climbs 2,865 feet in 26 miles through terrain that killed horses during the original construction.
Book Klook shore excursions for White Pass Rail — significantly cheaper than cruise line tours, with the same guide quality.
Ketchikan — Salmon Capital
Ketchikan receives more rainfall than any other US city (160+ inches/year) — bring rain gear. The Creek Street boardwalk over Ketchikan Creek is where the brothels were located during the salmon fishing boom. Today it’s a charming area with boutique shops.
Bear sightings: The nearby Tongass National Forest has black bears that can be viewed on guided floatplane trips to remote streams. Expect to pay $250-400/person for a half-day bear viewing excursion.
Glacier Viewing: What to Expect
Glacier Bay National Park: A UNESCO World Heritage Site and the premier glacier destination in Alaska. Most Inside Passage cruises include a full day in Glacier Bay with a Park Ranger on board. Icebergs float in the bay, and with luck you’ll see calving events (ice breaking off the glacier face).
Hubbard Glacier: A massive tidewater glacier in the Gulf of Alaska. At 76 miles long and 300 feet above water (with another 400 feet below), it’s the largest tidewater glacier in North America. More impressive in scale than Glacier Bay, though with fewer wildlife opportunities.
Best Time to Book
| Month | Pros | Cons |
|---|---|---|
| May | Shoulder season pricing, fewer crowds | Less glacier activity, weather unpredictable |
| June | Longest daylight (18-20 hours), best wildlife | Peak pricing, peak crowds |
| July | Warmest weather, salmon running | Most expensive week of the year |
| August | Shoulder season starts, school crowds | Peak pricing drops slightly |
| September | Fall colors, shoulder pricing, fewer crowds | Shortest days, weather can turn |
Savings strategy: Book 12-18 months out for early-bird discounts, or look for repositioning cruises (Seattle to Whittier or reverse) which often have lower per-night pricing than round-trips.
