Don’t just explore the surface of the earth — find out firsthand what's underneath it too. See mysterious natural formations and shapes in the deep, dim recesses of Gruta de Lourdes.
When you've finished exploring this San Pedro de Colalao natural underground attraction, why not make your way to Carlos Pellegrini Zoological Reserve, and Leocadio Paz Square? They're not very far from Gruta de Lourdes and also a favorite with many tourists.
