This cave is named after a hermit, Frei Mathias (brother Mathias), who lived in this cave in fear of pirates. The cave is 1,000m long, but most of the cave is difficult and caving equipment and experience is necessary. However, the entrance area is easy to visit and because of its loacation at the Pico Alto (2,351m asl), which is the highest mountain of Portugal, very popular.
