Concierge.com's insider take:
Once an island, rocky Monte Argentario is now connected to the mainland via two long, sandy spits: the Tombolo della Giannella to the north and the southern Tombolo della Feniglia, a nature reserve where roe deer graze under the umbrella pines. Halfway along a third, central spit is the walled town of Orbetello, a former Spanish colony that still has a relaxed Andalusian vibe; the surrounding lagoon is famous for its eels…and mosquitoes. On Argentario itself, sun, sea, and water sports are the main draws in Porto Ercole and Porto Santo Stefano, the peninsula's two main towns. At the Cala Galera Marina (www.marinacalagalera.com) in Porto Ercole, you can charter a private yacht or sailing boat with or without crew, or take dive courses at the Mahaba Diving Center (39-0564-831-187;www.mahabadiving.it). Ferries (including car ferries) leave Porto Santo Stefano six times daily in high season for the beautiful island of Giglio, and once a day at 10 a.m on Wednesday, Saturday, and Sunday (passengers only), returning at 4 p.m., for the smaller, wilder island of Giannutri (39-0564-812-920; www.maregiglio.it). Both places are wonderful for hiking and diving.
