Planning Your Time
Your first decision, particularly given limited time, is between the two Rivieras. The Riviera di Levante (east of Genoa) is more rustic and has a more distinct personality, with the unique Cinque Terre, ritzy Portofino, and the panoramic Gulf of Poets. The Riviera di Ponente (west of Genoa) is a classic European resort experience with many white-sand beaches and more nightlife and accommodation choices—similar to, but not as glamorous as, the French Riviera across the border.
In either case, your second decision is whether to visit Genoa. Despite its rough exterior and (diminishing) reputation as a seamy port town, Genoa's artistic and cultural treasures are significant—you won't find anything remotely comparable elsewhere in the region. Unless your goal is to avoid urban life entirely, consider a night or two in the city.
