Regional Park of Decima-Malafede, Regional nature reserve in Rome, Italy

The Regional Park of Decima-Malafede is a protected nature reserve on Rome's southwestern edge, containing forests, crop fields, and wetland areas across a large expanse. The landscape shifts between wooded sections, open farmland, and marshy zones that support different plants and wildlife.

The reserve was established in 1997, but human presence in the area is far older: prehistoric remains lie in the sedimentary rocks beneath the park. The protected area covers about 6,145 hectares, mostly in Rome's territory with a smaller part in Pomezia.

The name Decima-Malafede joins two historic estates within the reserve's boundaries. Near the Solforata area, three small lakes sit among iron- and sulphur-rich deposits, a geological feature visitors can see on the ground. The reserve was established in 1997 and covers about 6,145 hectares.

The reserve lies in Rome's southwest, framed by the Grande Raccordo Anulare, Via Pontina and Via Laurentina, with the Pomezia municipal boundary to the south. Access is by car along these roads; the sources list no public transport, trails or parking facilities, so plan your approach before setting out.

Wild boars roam freely through the forests and open areas in substantial numbers, making their presence one of the park's defining ecological features. Visitors might spot traces of these animals or learn how they shape the landscape they inhabit.
