Following the course of the Regato dos Muiños and the path that runs to its mouth in the form of a small waterfall, we will find a set of 5 rehabilitated mills. In its surroundings we will be able to see several outcrops of eclogites, a key metamorphic rock for the study of the interior of our planet. If we follow the coastline to the beach of San Miro, the spectacular Pedra Furada or Furna das Grallas, with its almost 25 meters high, excavated more than 100,000 years ago by the erosion of the sea, stands out.
