Parco fluviale del Nera, Regional park around Nera River in province of Terni, Italy.

Parco fluviale del Nera covers about 2,200 hectares of the Valnerina in the province of Terni, from Ferentillo to the Marmore waterfall, and takes in the Velino and Nera rivers. Its woods are broadleaf, with pubescent oak, white willow, common alder, white poplar and beech, plus Mediterranean scrub and riverbank growth. Rare ferns and wild flowers such as orchids, mountain tulips, gentians and wild peonies grow here.

The park was established by regional law no. 9 of 3 March 1995, with the aim of protecting and enhancing the Nera river basin. It covers about 2,200 hectares in the province of Terni, in the municipalities of Terni, Arrone, Montefranco and Ferentillo, from the Marmore waterfall to Ferentillo.

Four municipalities share the park's territory: Terni, Arrone, Montefranco and Ferentillo. The protected area was created by regional law no. 9 of 3 March 1995, with the aim of protecting and enhancing the Nera river basin, so the park itself is a recent administrative framework around valleys that were farmed and fished long before.

The park covers about 2,200 hectares across the municipalities of Terni, Arrone, Montefranco and Ferentillo, between Ferentillo and the Marmore Waterfall. Access is therefore possible from several villages along the Valnerina, and the protected stretch includes both the Nera and the Velino rivers.

The park's woods and riverbanks shelter the wild cat and the Apennine wolf, alongside raptors such as the kestrel, the short-toed eagle and the golden eagle, plus the moorhen and kingfisher. Its flora ranges from pubescent oak, white willow, black alder, white poplar and beech to wild orchid, mountain tulip, gentian and wild peony.
