Monaco packs a glamorous punch for such a tiny country. The monarchy, which occupies just 500 acres on France’s Cote d’Azur, is a quick train ride from Nice and a favorite summer playground for the rich and famous. It’s known for the Grimaldi family and the Monte Carlo Casino, which has an old world, elite moneyed elegance that can’t be replicated, and people watching here takes on epic proportions. The microstate’s architecture oozes grace throughout its small circumference with compelling sites like the Prince’s Palace. Plan a trip for when the famed Grand Prix is in town or a weekend at the casino, in Monaco it’s all about being social and living la bon vie.
