The scenic route to Alaska through the fabled Inside Passage leads to the remote Glacier Bay National Park. Here you'll find a spectacular labyrinth of deep fjords and dramatic glaciers plunging into the ocean, ringed by snow-capped peaks reaching to 15,000 feet -- the highest coastal mountains in the world. The easiest way to visit is by cruise ship; the nearest highway is hundreds of miles away.
