On the whole, the environment is easily enjoyable, also through long walks in the water, a pleasant sensation in hot summer days.
A long, fluvial strip wedging itself into Matese mountains, with no road networks or other handiworks breaking up the habitat, not only visual, continuity, with uninterrupted vegetation constituted by alders and willows.
Its untouched landscapes and habitats support the preservation of its scenarios, fauna and vegetable species.
The environment shows untouched beauty, prevailed by wild-aspect places, a real ecological passage, a high-value biogenetic reserve.
Along the stream, some hydroelectric control units and numerous old watermills, close to each other, now abandoned, which were used to exploit waters with little canalizations of beaten earth or on characteristic stony arches, are an important heritage of industrial archaeology and draw the municipal administrations attention with recovery interventions and proposals. The remains of Samnite megalithic wall on the top of Montelungo hill overlooking the Volturno and Isernia Valley, the ruins of the medieval castle on the opposite top of the long ridge, overlooking the village of Longano, the bronze mask of Pre-Italic period are traces of the past.
