PORTO CERVO

Porto Cervo, the Costa Smeralda's hub, is a pastel-hued town mostly given over to fashionable restaurants, fancy boutiques, and posh bars wrapped around a wide harbor where the rich and famous's super-yachts dock during the summer months. In town, join the linen and cashmere set in the Piazzetta for a posh Campari spritz and a nice dose of people-watching once you've finished looking out the latest Gucci, Prada, and Louis Vuitton must-haves.

The coast's five-star hotels, dining scene, and, of course, its exquisite natural beauty attract rich jet-setters and billionaires in mega-yachts, royals, and celebs like as the Clooneys, Obamas, and Elton John (along with the accompanying paparazzi!).
