Monaco

The minuscule principality (0.75 square mile) of Monaco, which borders only France and the Mediterranean, is a special place — it's home to one of the world's most famous auto races and one of its fanciest casinos, with more people in its philharmonic orchestra than in its army. Don't look for anything too deep in this glittering little land of luxury; many of its 36,000 residents live here because there's no income tax. Yet despite high prices, wall-to-wall daytime tourists, and a Disney-esque atmosphere, Monaco is a Riviera must.
