Lungo and Ripasottile Lakes Partial Nature Reserve Part of the municipal territory is included in a nature reserve of which the aforementioned springs of Santa Susanna are part, but also the Lungo Lake and Ripasottile Lake. Inside the reserve there is a wetland surrounded by reedbeds, which provides shelter for numerous species of migratory birds, and has maintained an environment similar to that before the reclamation of the Piana Reatina.
