Inside Passage or Gulf of Alaska?
- Inside Passage round trips usually sail from Seattle or Vancouver and visit ports such as Juneau, Ketchikan and Skagway, often with a day of scenic cruising near a glacier.
- One-way Gulf of Alaska cruises sail between Vancouver and Seward or Whittier (the ports for Anchorage). They reach further north and pair well with a land tour to Denali.
- Cruise tours combine a cruise with a few nights on land, often by rail and coach, to see Alaska’s interior.
When is the Alaska cruise season?
The Alaska season runs roughly from May to September. Early and late season (May and September) can be quieter and better value, with cooler weather. Mid-summer brings the longest days and the warmest temperatures. Wildlife sightings vary through the season, so if you have a particular animal in mind, check when it’s most likely to be seen.
Pack layers and waterproofs whatever the month: weather in Alaska changes quickly, and it’s often cool on deck near the glaciers.
Departure ports and getting there
Seattle and Vancouver are the main departure ports for round trips. Because of US cabotage rules, foreign-flagged ships sailing round trip from Seattle must call at a foreign port, which is why these itineraries usually stop in Victoria, British Columbia. If you sail from or via Canada, check Canadian entry requirements for your nationality.
From the UK and Europe, Alaska cruises are long-haul fly-cruises, so it’s worth allowing a night or two in Seattle or Vancouver before you sail.
Tips for an Alaska cruise
- A balcony or a good public viewing spot makes a big difference on scenic cruising days.
- Popular excursions such as floatplane flights, whale watching and glacier helicopter trips can sell out early.
- Bring binoculars and a camera with a zoom lens.
- If you plan a cruise tour, compare the land portion carefully: it varies a lot between lines.
