Built with vast troves of cash by the Aga Khan in the 1960’s, Sardinia’s Costa Smeralda, one of the original jet-set getaways, offers Italy’s most glamorous slice of la dolce vita. Perched above the Mediterranean’s translucent blue-green waters is an exclusive resort community inspired by the island’s weathered fishing hamlets. For romantics who prize originality, Cala di Volpe—the “Bay of Foxes”—resembles a medieval jumble of crooked towers, rough porticoes, and rakishly angled turrets. Inside, narrow passageways honeycomb the white stucco interior. Gobs of colored glass wedged into the plaster admit rainbow sunbeams. Juniper beams support the ceilings of the hotel's 97 sea view rooms and 17 suites, each of them whimsically furnished with Sardinian arts and crafts. Tee it up at Pevero Golf Club, a sturdy, scenic Robert Trent Jones layout chiseled into fissured granite where the scents of myrtle, juniper, and lavender mingle with the sea air.
