Peso and Vales do Rio are unequivocally connected to the Zêzere, where it still has the characteristics of its Cova da Beira course, of slow flow with wide alluvium on both banks, leafy riparian galleries of ash-trees, willows, alders and poplars (unfortunately invaded by acacias in some places). The fertility of the land bordering the river allows for multiple crops, irrigated by lifting water directly from the river bed, currently by motor pumps, in the past by hydraulic wheels.

Possibly due to the proximity to Covilhã, the wool industry still has some representation and presence in the local economy. Mining is now an almost erased memory but, there is still a physical testimony of a forgotten mine between pine forests, in a remote place where wolfram was extracted.
