Two cities with real Tsar Power, Moscow and St. Petersburg are the odd couple of Russia: one, the heart of the nation and home to the history-rich Kremlin, the other, a city born of the passion of its founder, Peter the Great, and today a gigantic Faberge egg stuffed with great art, sunset-colored palaces, and lollipop-striped cathedrals. As more travelers than ever are making their own voyages by cruising the Volga river, which connects Moscow and St. Petersburg, Fodor's Moscow and St. Petersburg also details many of the splendors of the connecting Golden Ring area.
