Lapiás do Casmilo

Highlight • Natural Monument

The Lapiás do Casmilo are an impressive geological formation carved by water erosion over limestone. Known as "stone cemeteries", they emerge from the karst landscape of the Buracas do Casmilo valley, creating a landscape of exposed rocks, full of grooves and sharp edges.

Time and water have shaped this unique relief, infiltrating the rock and creating striations that reveal the path of the runoff. In steeper areas, the marks on the stone become even more evident, testifying to the power of nature in this mineral spectacle.

Poios Canyon

Highlight • Gorge

The Poio Valley stands as a well-kept secret of the mountains, preserved for centuries by its rugged, steep, wild, and inaccessible geography. Only shepherds and adventurers used to know these paths. Perhaps that is why a rare fauna found refuge here. It is one of the largest fluviokarstic canyons in Portugal, a valley patiently sculpted by water, which left monumental slopes and a breathtaking landscape.

To the south lies Poio Velho; to the north, the more famous Poio Novo, two chapters of the same magnificent landscape.

Pedra Ferida Waterfall

Highlight • Waterfall

Incredibly beautiful waterfalls + bathing pools can be found here. There are several cascades in which you can swim. The descent is not easy and requires sturdy shoes. You also have to scramble a bit. Safety ropes sometimes help with the descent.

December 12, 2025, Punto panoramico al Monte da Ovelha

Known as Serra da Portela or Serra do Anjo da Guarda, this is a natural viewpoint overlooking the Pousaflores Valley, where the landscape is filled with life and aromas. Wild orchids, rupicolous plants, "cucas" (a type of gourd), wormwood, and the fresh scent of thyme, which wafts away with every step, flourish among the limestone rocks. Here, atop Monte da Ovelha, human presence has left its mark: traditional windmills, a small chapel dedicated to the Guardian Angel, the Stations of the Cross for Good Friday, and initiatives celebrating bread and cornbread. It's also a place made for lingering: sitting at a table, lighting a grill, or simply gazing out.
