The largest tidewater glacier in Prince William Sound and the second largest in the entire state of Alaska, Columbia Glacier is 25 miles from Valdez and covers more than 400 square miles. The face is more than 3 miles wide and is rapidly moving backward at a rate of 4 feet per day in the summer! Enjoy an hour boat ride to the glacier, then kayak amid towering icebergs, gliding through bays that are completely inaccessible by motorized boats, and observe sea otters and harbor seals hauled out on the ice floes. Keep a close lookout for sea lions, bears and, quite often, whales! Hike on recently uncovered landscape and in the adjacent old growth forest.
