Juneau, Alaska is considered by many to be the most beautiful capital city in the nation. Checking in at just a little over 3,100-square-miles, Juneau qualifies as the biggest American city - geographically, that is. The terrain is hilly and winding, and narrow streets present a small-town quaintness existing side-by-side with cosmopolitan sophistication. You'll find great shopping, fine restaurants and superb museums.
