The Aniene River, which feeds these falls, was a critical source of water for ancient Roman aqueducts.
The waterfall is situated within the Parco Regionale dei Monti Simbruini, the largest protected natural area in the Lazio region.
The geological structure of the area is primarily composed of limestone, resulting in unique karst erosion patterns along the riverbed.
Cascate di Trevi are a series of natural waterfalls located within the Simbruini Mountains Regional Park in the Lazio region. The falls are fed by the Aniene River, which carves through the karst limestone landscape of the valley. The area is characterized by dense woodland and significant water flow, particularly during the spring snowmelt. The waterfall site is accessible via a short trail system that descends into the valley floor. The environment serves as a protected habitat for diverse mountain flora and fauna endemic to the Apennines.
The wooden bridge or viewing platform located at the lowest point of the trail for a direct frontal view of the main cascade.
Wear sturdy, waterproof hiking boots as the path to the falls can be slippery and muddy.
Bring trekking poles if you have stability concerns, as the descent involves uneven natural terrain.
Pack a light jacket, as the microclimate near the waterfall is significantly cooler than the surrounding area.
Do not attempt to swim in the plunge pools, as currents can be deceptive and the water temperature is near freezing year-round.
Trails may be inaccessible during heavy winter snowfall or extreme rainfall events; check regional park alerts before departure.
