Caminho dos Poios with views of the Vale Glaciar do Zêzere
The Caminho dos Poios, or the "Poios" (agricultural terraces) Trail, offers spectacular views of the vast and imposing Vale Glaciar do Zêzere, a masterpiece of nature sculpted by ancient glaciers. This trail winds along the sides of the mountain, offering panoramic views that embrace the entire "U" valley, highlighting its grandeur and the singularity of the landscape.


The route allows you to appreciate not only the glacial morphology with its steep walls and moraine deposits, but also the human ingenuity in adapting the territory, as evidenced by the terraces that characterize the landscape in some areas. It is an immersion in the wild beauty of the Serra da Estrela, with the opportunity to contemplate one of its most significant geological treasures.
