Cruising is the best way to visit Glacier Bay where you can listen to lectures from the Glacier National Park rangers while on board. Visiting the area is dependent on weather conditions as the glaciers are moving and can and do shed ice at any time. There are two famous glaciers in this area.
The Marjorie Glacier is 21 miles long and flows about six feet daily. The John Hopkins Glacier is in the northwest Glacier Bay Fjord and is 12 miles long. While watching the glaciers, look out for Alaskan wildlife as it is common to see whales in this area and a proliferation of birds.
The Dawes Glacier is northwest of Sitka and southeast of Juneau and starts near the Alaska/Canada boundary. Viewing glaciers is an excellent reason to book an outside cabin or suite with a balcony on a cruise ship because the views close up are unforgettable.
The Dawes and Endicott Arm Glaciers are approached via a narrow passage and are spectacular with the glacial ice formations. Unfortunately, these glaciers are thinning rapidly due to tidewater formation and also global warming.
