The forest along which the path runs is a forest of mountain bank that is characterized by the absence of the alder, being frequent, however, many of the species that accompany it in lower areas: ash, maples, birches, mountain elms, lime trees, willows, and even some beech or oak.
Many species of fauna find refuge and feeding on the riverbanks and others are closely linked to these aquatic environments on which they depend for their survival. Such is the case of birds like the laundress or the aquatic blackbird, or of mammals like the otter, expert and voracious hunter.
The vegetation cover of the Reserve is characterized by its high degree of naturalness of the scant evidence of human activity. Mature sessile oak forests (Quercus petraea) cover almost three quarters of the area. In these forests, oak is the dominant species, accompanied mainly by birch. In the arboreal strata, the archaelon stands out, and rowan, hazel and holly trees appear punctually. Among the bushes, white heather and cranberries develop mainly. In the most humid areas, the presence of beech is frequent.
