The Silver Coast is one of the most beautiful coastal stretches in Tuscany and Italy, located in the southern part of the Maremma between the lagoon of Orbetello and Montalto di Castro. The area extends for about sixty kilometers in the stretch of coast between Talamone (Maremma Regional NaturalPark) and Pescia Romana (Lake Burano) and is characterized by the promontory of Monte Argentario. An ancient island of the Mediterranean, Monte Argentario, welded to the mainland by two sandy cordons called Tomboli di Giannella and Feniglia that enclose inside the Lagoon of Orbetello, stands in front of the Island of Giglio and the island of Giannutri and culminates with the 653 meters of Punta Telegrafo. All around the Argentario is a succession of enchanting beaches, cliffs, precipices, caves, ancient watchtowers and imposing fortresses, built by the Spaniards in the 1500s to defend the State of the Presidios,which allowed (due to their particular strategic position) the control of vast territories and maritime traffic. Along the coast, next to sunny expanses of fine beach, there are thick and bright pine forests, interspersed with precious wetlands, refuges for numerous species of migratory birds and plant associations, protected and managed by the WWF: Oasis of Protection of the Lagoon of Ponente di Orbetello and Nature Reserve of Lake Burano. Coastal lake, that of Burano, still saved from cover-up thanks to the so-called Etruscan Tagliata, an admirable engineering work that was to preserve the ancient port of the city of Cosa (Roman colony founded in 273 bc.C.), located at the of the promontory of Ansedonia, ensuringthe constant flow and ebb of water.
In the sea between giglio and the coast of the Uccellina Park emerges an archipelago of rocks, the Formiche (Ants) of Grosseto. They are three uninhabited limestone islets, included in the Tuscan Archipelago: Formica Grande, Formica Piccola e Formica III. On Formica Grande, surrounded by dangerous dry, there is an automatic beacon.
