From the Princess Website: "Princess is one of a select few cruise lines permitted to cruise the pristine waters of Glacier Bay, the highlight of our 7-day Voyage of the Glaciers cruise. Just west of Juneau, this breathtaking national park and preserve boasts some of the world's most spectacular tidewater glaciers, such as Margerie Glacier, which often drops colossal chunks of ice into the sea. During your scenic cruise, friendly Park Rangers will join the ship to share their knowledge of this amazing place and host a fun Junior Ranger program for kids. They may even be able to help you identify Glacier Bay's abundant wildlife, including humpback whales, sea otters, porpoises, harbor seals, black bears, mountain goats, bald eagles and large colonies of seabirds. Take in the awe-inspiring scenery as you enjoy an unforgettable day of sailing through this park, where you'll glide along emerald waters and past calving icebergs..."
