I know of the likely whale areas in Alaska. But firstmost- you need to be out on a front open deck dressed warm with knit hat and gloves. It is usless to watch from the side of the ship. You need binoculars to keep scanning ahead watching for the blows and keep tracking them. It is a job requiring a considerable amount of time that few cruisers are willing to invest in. I always am on the watch all sailing hours, but it will usually be the same 25 or so people that will be there. Likely areas- several hours before and after both Juneau and Glacier Bay through Ice Strait. Last sailing day it is advisable to be out from early afternoon through dusk. All the more reason to get late seating- like I always do.

Your last sailing day is the bonus. Only most likely place to see orcas- along Vancouver Island in the 4-8pm area. Before that likely humpbacks, white sided dolphins, dolls porpoises. I have a lot of experience whale watching both coasts and Maui. It is extremely rewarding for that 2 minutes of viewing!!!!!
