In Ansedonia we find two beaches: the first (Northwest side) overlooks the Argentario and the other (Southeast side) faces the coast of Capalbio. In both the sand is fine and dark and the sea is shallow for several meters from the shore.
The Ansedonia beach facing the Argentario is the final part of the Feniglia tombolo (a little stretch of land). Behind the beach there is the pinewood of the forest reserve, where it is not difficult to see deers. If you want to walk, you will find wide completely deserted areas, where logs brought to shore by winter storms make suggestive and fascinating environment.
The beach facing Capalbio is the initial part of the coast that continues up to Lazio. This part of the beach is characterized by the presence of the Tagliata, a channel that dates from the Etruscan-Roman period cut into the rock in order to prevent the silting up of the Harbor, of the Puccini Tower (or Tagliata Tower) and the Spacco della Regina, a natural cavern just a short walk from the beach.
