Beyond the main embankment of the River Po lies the “Caldarén” Wood, a natural gateway to the Great River for those arriving from Gualtieri. 

At the beginning of the 20th century, this area was used for sand or clay extraction, materials employed in brickmaking and road construction. The extracted materials were transported to the “Altomani” kiln by a cableway system equipped with small containers known locally as  the “cadarén”. After extraction activities ceased, a thriving woodland gradually took root, featuring a variety of tree species - some of them rare.
Covering around 13 hectares, the area now represents a typical Po Valley habitat, dominated by poplars and willows and inhabited by species such as the European Green Woodpecker, the Great Spotted Woodpecker, titmice, owls and other birds that flourish in this woodland rich in dead and decaying trees.
