The panoramic road Strada panoramica starts in Porto Santo Stefano allowing splendid views of the coast and the Tuscan Archipelago.

Monte Argentario is a promontory stretching towards the Tyrrhenian Sea in correspondence of the two southernmost islands of the Tuscan Archipelago, Giglio and Giannutri.

The high quality speleothems that have been collected from this cave have allowed scientists to study the 215,000 year history of sea-level oscillations in this region.

[4] The promontory, probably already inhabited by the Etruscans, was a personal property of the Domitii Ahenobarbi family, who obtained it in return for the money they lent to the Roman Republic in the Punic Wars.

Following the history of Orbetello, the promontory was a possession of the Aldobrandeschi, the Orsini, King Ladislaus of Naples and Siena, until Spain acquired it in the late 16th century.
