Definitely one of the most beautiful coastlines of Italy, The Silver Coast is a promontory of the province of Grosseto, lapped by the waters of the Tyrrhenian Sea and the Lagoon of Orbetello. Administered by the municipality of Monte Argentario, is located along the Tuscan coast east of 'Giglio Island and north of Giannutri. The highest point reaches 635 meters s.l.m. on the summit of Mount Telegraph.

Like the promontory of Piombino and other minor headlands, Also the Argentario was originally an island, that over the centuries has come to see connected to the nearby mainland, for lifting before the Feniglia Tombolo (action of sea currents) and then also bolster Giannella (storage material from the nearby river Albegna).

Once joined to the mainland by two cordons of sand, the inner part of the promontory between them has failed to find wet from Lagoon of, whose origin is coeval with the processes that led to the transformation of the Argentario promontory from island to.

The territory of the promontory is almost entirely hilly and sometimes steep, softened only by man who created the time of the terraces where it is grown mainly screw (Ansonica Argentario Coast) and locally the olive.

The only flat area, however, very limited surface, is located in eastern cape, in the locality Terrarossa, near the end point of nineteenth-century artificial dam, on which was built during the last century the road to the place of the disused railway Orbetello Orbetello-Porto Santo Stefano.

The two towns are located on the headland Porto Santo Stefano (north-west), which houses the town hall of Monte Argentario, Porto Ercole and south-east from the more ancient origins.

The interior has been completely hilly Argentario, with slopes that tend to rise more slowly in the north-east of the promontory, starting with the small flat area of ​​Terrarossa.

Some of these hills at Terrarossa were exploited in the past for the extraction of pyrite, from which it derived the name of this place. The mines were served by freight trains that stopped at the station Terrarossa, located along the disused railway Orbetello-Porto Santo Stefano, which created a link between the Valley and the Port of Venice, where it flowed into the Tyrrhenian railway. The existence of these mines is also demonstrated by the presence of towers, visible from Tombolo Feniglia and Eastern Lagoon.

While on the northeast side of the slopes tend to rise more gradually, there are steep cliffs along some coastlines, which are very sharp at the tip of Cape Man (west coast), along different stretches of the coastline south-western area overlooking Punta Avvoltore along the south-eastern, where there are steep walls and dolomite, that in the past have caused some landslides.

Just in the immediate hinterland of Punta Avvoltore, are reached 635 meters s.l.m. the top of mountains called Punta Telegraph, the highest peak in the entire Cape, reached by climbing more gently from the north-eastern, after passing the religious complex of the Convent of the Presentation in the Temple and the Church of St. Joseph Novitiate. The ridge that includes the highest peak is easily recognizable from a distance for the presence of numerous radio and television repeaters; on the summit of Mount Telegraph is also the meteorological station of Monte Argentario, officially recognized by the World Meteorological, headed by the Air Force Meteorological Service.
