Glacier Bay National Park, Alaska

Glacier Bay is the crowning jewel of the cruise-ship industry and a dreamy destination for anybody who has ever paddled a kayak. Seven tidewater glaciers spill out of the mountains and fill the sea with icebergs of all shapes, sizes and shades of blue, making Glacier Bay National Park and Preserve an icy wilderness renowned worldwide.
Apart from its high concentration of tidewater glaciers, Glacier Bay is a dynamic habitat for humpback whales. Other wildlife seen at Glacier Bay includes porpoises, sea otters, brown and black bears, wolves, moose and mountain goats.

The park is an expensive side trip, even by Alaskan standards. Plan on spending at least $400 for a trip from Juneau. Of the 500,000 annual visitors, more than 95% arrive aboard a ship and never leave it. The rest is a mixture of tour-group members, who head straight for the lodge, and backpackers, who gravitate toward the free campground.
