Though Monaco is best known for its glitterati, you don't have to be a jetsetter to ogle the stunning vista of Monaco Harbor. All you need do is struggle up the steep trail to Palais Princier, the Grimaldi's castle and symbol of their reign over this municipality since 1297. Afterward, wander the streets of adjacent Old Town. Later, quench your thirst in the Hotel Metropole's glamorous Lobby Bar. There, you'll feel like one of the in crowd.
