The Inside Passage is a string of islands in Southeast Alaska. Seven- to 10-night Inside Passage cruises typically sail round trip from Vancouver, Victoria, Seattle, or San Francisco, and head along British Columbia’s forested coast as far up as Skagway, with visits to Ketchikan and Juneau. They also include a day spent cruising through one of the glacier areas: Glacier Bay, Hubbard Glacier, or Sawyer Glacier.
