Shabby-chic villas, Chianti and olive oil aren't all Tuscany has going for it. The Tuscan Archipelago National Park is a reminder of the region's great diversity. Located on the island of Elba — best known for Napoleon's exile — the Hotel Ilio makes a pretty base for underwater explorations. A PADI dive center sits adjacent to the hotel, and the nearby shallows ripple with local fish varieties swimming through fields of vibrant seaweed. Farther out, divers can drift with seahorses among coral sea fans and explore the remains of ancient Roman merchant ships. For those who prefer to stay closer to the surface, snorkeling tours with marine biologists are offered.
