"Horseshoe" gravel segment that takes via dei Fanti near Maserada, passes the green area of Parabae and continues on the Strada delle Grentine towards Spresiano. Having reversed the route in the direction of the Piave river, we return towards the hamlet of Salettuol through the Codibugnolo Naturalistic Oasis, a floodplain area of 24 hectares located along the course of the Piave in the central stretch of the river between the municipalities of Spresiano and Ponte of Piave. The oasis, due to its particular geomorphological conformation and the biological varieties present, offers an ideal educational reservoir, which is why the Piavenire Naturalistic Route was born, conceived by the local Legambiente section to demonstrate, with maximum evidence, the richness natural that still finds refuge in the remnants of riparian forest.
