The route leads to the slopes of the Sever River, passing through the ruins of the Chapel of Santa Margarida. It crosses Ferreira's threshing floor, following paths between eucalyptus trees and some pine trees, once trodden by peasants and smugglers. On the riverbanks there are many iron fountains and headwaters. Then you find the Nogueira water-mill, and the Arthur's water-mill, which today are submerged. With Spain on the other bank, we find a small, abandoned shale shelter. Beginning with a sharp rise among the eucalyptus. Ahead, the landscape of the cork oak marks the return, between walls and shale ruins.
