Monte Carlo

Nothing more than a tiny Principality, Monaco steals much more of the international limelight than its size decently permits. But it's the Grand Casino, of course, where you must peer into the enchanting Salon Rose to see its naked nymph-clad ceiling. It's also the palace and the cathedral, the Rock of Monaco and the harbor, packed to the gills with million-dollar motor yachts—and those are just the modest ones.
