With its 60 kilometres long, the Valley represents an ecosystem extremely rich in biodiversity on which the parks insist, namely the Aples-Maritimes Natural Park and the Gesso and Stura River Park. The part of the valley terrory included in the Alpes-Maritimes Park insists on the territory of the Aisone district with reference to the Valletta and Reduc Valleys. In Aisone there is also a multipurpose structure, the Caves Tavern, a visitor centre and a commercial activity that allows tourists and interested to orient themselves on this portion of the park.
The Gesso and Stura River Park, on the other hand, develops in the lower Valley, where the Stura of Demonte once reaches the plain welcomes the Gesso stream in its bed.
Spread over 4000 hectares of territory, 60 kilometres of river and almost 100,000 inhabitants, the Gesso and Stura River Park represents a link between the mountain area and the plain. It includes in its territory the districts of Borgo San Dalmazzo, Vignolo and Roccasparvera, or some of the districts of the Stura Valley that for centuries have represented a bridgehead between the valley territory and the foothills.
