Tracy Arm is a green wilderness, and a narrow fjord, but due to ice (and time to navigate the narrow channel) often ships don't make it all the way to the end to see the twin Sawyer Glaciers. Hubbard Glacier is a vast wall of ice, a behemoth of a glacier. However, due to all that ice meeting warm air, fog seems to happen more often there. The College Glaciers are a rare treat, usually only visited on the "one way' itineraries. However, the "must do" everyone seems to agree on as the *best* glacier experience is Glacier Bay.
