Monte Argentario is a promontory that stretches out into the Tyrrhenian Sea opposite the two most southerly islands of the Tuscan Archipelago: Giglio and Giannutri.

It too was originally an island, but over the centuries the combined effects of the sea currents and the river Albenga created two tombolos (sandbars/spits) known as Giannella and Feniglia that joined the island to the mainland and also led to the creation of the Ortobello Lagoon.

Monte Argentario is characterised by its mountainous terrain, softened only by years of hard work by  man to create terraces used mostly to cultivate vines.  The highest point of the promontory, a 635m  is Punta Telegafo.

The jagged coastline is full of stony coves and inlets, that do however embody the incredible beauty of nature.

There are two  seafaring towns located here that together form the commune of Monte Argentario. Porto Santo Stefano, home to the town hall faces north, whilst its smaller neighbour. Porto Ercole faces south.
