The Circeo dunes site is an ecologically significant area located on the central coast of Italy in the Lazio region. This site borders the SCI (Site of Community Importance) areas of Lakes Fogliano, Monaci, Caprolace, and Pantani dell’Inferno and Lake Sabaudia. It represents one of the most significant example of dune habitat remaining in Italy. The coastal dunes, which extend along a stretch of coastline between Capo Portiere and Torre Paola, reach remarkable heights up to 27 meters. These dunes are situated between the sea and four coastal lakes: Fogliano, Monaci, Caprolace, and Sabaudia, which create a unique and diverse environment. The dunes facing the sea are characterized by the predominance of prickly juniper scrubland and some well-preserved areas of psammophilous vegetation. During the summer period, it is possible to admire the spectacular blossoming of sea lilies which is a captivating and picturesque natural event.
Furthermore, the site represents an important habitat for ornithological species of community interest, such as the nesting Kentish plover. The presence of this species highlights the necessity of preserving the area also for bird protection.
