Grutas de Mira d'Aire
Discovered in 1947, these are the largest caves in Portugal. They have a gallery/room/shaft configuration and their formation is due to erosion and tectonic changes. They feature underground lakes and rooms with beautiful limestone formations. They have two elevators and are 110 meters deep. Here lies the Great Lagoon, formed by the Rio Negro, an underground watercourse that, in winter, forms the Mira de Aire Lagoon. In 2010 it was classified as one of the Seven Natural Wonders of Portugal.
