The Cascata delle Marmore is one of the tallest human-made waterfalls in Europe, with a total drop of 165 meters.
The waterfall's flow is diverted for hydroelectric power generation, creating distinct periods where the cascades are dry or reduced to a small stream.
The ancient Romans constructed the Curinga canal to divert the Velino River into the Nera River to combat malaria-carrying stagnant water.
The park contains the 'Sentiero 5', a route that provides access to the Balcone degli Innamorati, located directly behind the upper waterfall tier.
Local flora includes species adapted to the calcareous tufa environments created by the waterfall's mist.
The park spans multiple municipalities including Terni, Arrone, and Ferentillo.
The chemical composition of the water, rich in calcium carbonate, causes the continuous deposition of travertine rock formations along the waterfall path.
Parco Fluviale del Nera is a protected natural area situated in the Umbria region, centering on the Nera River valley. The park features the Cascata delle Marmore, an artificial waterfall complex originally engineered by the ancient Romans in 271 BC to drain stagnant marshes. Water flow is regulated by a hydroelectric plant, resulting in scheduled release times rather than a constant stream. The landscape comprises limestone cliffs, diverse riparian flora, and extensive hiking trails linking the riverbank to the upper plateaus. It serves as a hub for river-based activities including rafting, canyoning, and kayaking. Archaeological sites and remnants of industrial history are integrated into the park's walking routes. The area is designated as a Site of Community Importance under the European Natura 2000 network due to its biodiversity.

Check the daily water release schedule online before arrival to ensure you see the waterfall at full volume.
Wear waterproof footwear or carry a poncho, as the mist at the waterfall base creates significant spray.
Follow marked hiking trails closely to avoid entering restricted areas near the hydroelectric conduits.
Attempting to swim in the waterfall basin or the regulated river sections, as current speeds fluctuate rapidly due to hydroelectric operations.
Water flow is strictly regulated; the waterfall is frequently reduced to a minimal flow on weekdays outside of summer and holiday seasons.
Stick to designated paths to protect local flora and avoid slippery, non-secured cliff edges.
