Casa das Penhas Douradas is a mountain hotel in a former sanatorium, suited to an offsite that pairs time outdoors with a slower pace. It stands in the Serra da Estrela Natural Park and UNESCO Global Geopark, in the mountain settlement of Penhas Douradas, whose sanatorium architecture has been preserved. Local forms and natural materials shape the buildings, with cork on an exterior and birch lining inside. Walking routes marked by the hotel in partnership with the natural park link into the area’s wider trail network. At Nubbin, the surrounding forest and the winter crackle of the fireplace set the scene for meals; the mountain spa uses oils made from herbs gathered in Serra da Estrela.
