Spend the day onboard sailing through the 3.3 million acre Glacier Bay National Park, which is actually the largest UNESCO protected biosphere, consisting of more than 50 tidewater and terrestrial glaciers. Snowcapped mountains surround your scenic cruise as Glacier Bay treats travellers to an abundance of wildlife on display including humpback whales, sea otters, porpoises, harbor seals, black bears, mountain goats, bald eagles and large colonies of seabirds.
