The Osa-Gabii and San Vittorino itineraries traverse one of the most beautiful and historically significant areas of the extreme territory of Municipality VI. This region forms the eastern slope of the vast plain encircling Rome, known as the Agro Romano Antico. This triangle of land is delineated by three consular roads: Tiburtina, Prenestina, and Casilina/Labicana. The area also shares its borders with several municipalities in the metropolitan area of Rome, enriching its cultural and geographical significance.

The Agro Romano Antico, particularly the part located in Municipality VI, is abundant with naturalistic and historical-archaeological treasures, many of which remain underexplored. This unique region is defined by its remarkable preservation of natural landscapes and historical structures, providing a stark contrast to the urban sprawl that has affected much of Rome's outskirts.

This region offers numerous trails where the interplay of nature and culture creates a unique experience for visitors. These paths, ideal for exploration on foot, allow travelers to immerse themselves in the historical and natural richness of the Agro Romano Antico. From the serene countryside vistas to the evocative ruins of ancient structures, the itineraries of Osa-Gabii and San Vittorino provide a rare opportunity to step back in time while enjoying the unspoiled beauty of the Roman countryside.
