The Italian jet-set can't get enough of holidays to Forte dei Marmi. And it's easy to see why. This swanky seafront gem is the most exclusive beach resort in northern Tuscany. We're talking seductive sands, chi-chi restaurants, and more designer shops than you can shake your credit card at. On top of that, the countryside here is just as breathtaking as the coastline, so dive right in and discover a pretty patchwork of emerald forests and rugged peaks.
