Once an exclusive retreat for the crème de la crème of society, Porto Cervo is still one of the world’s most luxurious resorts, but thanks to the 2004 opening of an airport in nearby Olbia, you don’t have to own a megayacht to vacation here. You do, however, need to realize this is definitely not a backpack-and-Eurail Pass destination. Designer boutiques, luxury spas, fine restaurants and exclusive nightspots abound.
