It is a well-known fact that the villa that houses the Hotel du Palais in Biarritz, overlooking the Bay of Biscay, was built by Napoleon III for his stunning wife, Eugénie. Few travelers realize, however, that the Spanish-born beauty had been to Biarritz before, and that it was she who convinced her husband to visit the resort town in the first place. Today, the scarlet-and-cream-colored seaside villa still channels its grand heritage. Rooms are lavish and high ceilings create a breezy, destination-appropriate vibe. Equally sumptuous is La Rotunda restaurant, where the beau monde comes for special occasion meals. The extensive wellness facility, complete with a Guerlain spa and lounging areas with sea views, is the kind of enclave that Eugénie surely would have loved.
