Inside Passage Alaska Cruise Day 2 PM Leaving Ketchikan and heading toward Juneau on the Inside Passage, very smooth ride. Alaska’s Inside Passage is hundreds of miles from Puget Sound, Washington, through the British Columbia coast and into the Gulf of Alaska, the Inside Passage includes more than 1,000 islands, seemingly endless shoreline and thousands of idyllic coves and bays. Beautiful and serene. Mountains on both sides. Sunset in the Inside Passage.
