Locally, these small hills are called "cabeços". Cabeço da Silheira is one of the highest in the region, reaching 200m in altitude. It is therefore natural that it was chosen as the site for the installation of water tanks that supply the region's public water supply network.
You can reach Cabeço da Silheira via a small asphalt road (very steep) or via one or two existing trails. If you choose to go along the trails, we recommend a mountain bike.
