Spend the day exploring Glacier Bay National Park. A UNESCO World Heritage Site and a Biosphere reserve, Glacier Bay National Park is best known for its 8 active tidewater glaciers, some estimated to be 4,000 years old and remnants of the last glacial period, known as the Little Ice Age. A National Park Ranger will be with you to explore hidden coves and seldom-hiked trails. Wildlife viewing opportunities abound with resident sea lions, mountain goats, sea otters, bears, moose, eagles and puffins as well as spectacular scenic backdrops. Your day is complete with a stop in Bartlett Cove for a visit to the Park Service's headquarters.
