Viewing the magnificent grandeur of immense glaciers is surely one of the highlights of a journey to Alaska. Sail along a cliff face over six miles wide, 300 to 400 feet from peak to sea level and 300 feet from sea level to the bottom. As Hubbard Glacier advances, listen to the symphony of creaks and groans as it moves and calves. This makes for some exciting moments when the huge chunks of ice crash into the bay creating a wonderful sound called 'white thunder' by the Tlingit people. Please be advised that due to the under-developed nature of this destination, organized tours are not available.
