7 Decades of discovery and disclosure
The Sociedade Portuguesa de Espeleologia - SPE founding members, among which were included several locals from Mira de Aire, and many other initial enthusiasts of Mira de Aire, and later their followers, who contributed decisively to the revelation of the Caves of Mira de Aire as the biggest tourist underground phenomena in Portugal. This 70-year-old collaboration is still alive, thanks to the foresight and sense of mission of Grutas de Mira de Aire, S.A. company administrators and the determination and personal commitment of the speleologists and directors of the SPE.
