Natural Monument Grotte of Falvaterra and Rio Obaco
The incessant action of groundwater, resulted in the formation of the beautiful caves of Falvaterra, developed within the limestone cliffs of Monte Lamia. The beauty of the place meant that the area of small rivers and of the underground comlpex of Falvaterra would become a Natural Monument of the Lazio Region in October 2007. The protected area covers more than 130 ha and includes the entire drainage basin of the Rio Obaco to its confluence with the River Lot, with diversification of environments and microenvironments of great biological interest.
