Beautiful waterfalls found on the Via Francigena between Sutri and Campagnano di Roma... it's a shame that their waters are particularly polluted.

Cascata di Monte Gelato, located in the Parco Regionale Valle del Treja (Treja Valley Regional Park), is a captivating natural wonder in the Lazio region of Italy. It consists of a series of small waterfalls along the Treja River. Some of these falls are natural, while others have been shaped by human intervention. The constant flow of water over layers of volcanic rock has sculpted these picturesque waterfalls for millennia
