Where the whales are
Favorite Channel and Saginaw Channel are the top spots for humpbacks.
Kinds of tours
Small boat
Fewer people, more flexibility. Good for photographers.
Big catamaran
Some seat over 40 people. Steadier, with indoor seating.
Combo tours
Some pair whale watching with glacier viewing or a lighthouse stop.
Kayak
Paddling tours are offered too, for a quieter look.
Cruise day?
Pick a morning departure if your ship schedule allows, and leave a buffer before all-aboard.
