Cueva Juan Nieves is one of currently five entrance to the sistema del Rio Encantado. They are called Rio Encantado (175 m asl), Escalera (200 m asl), Vidrios (200 m asl), Cueva Juan Nieves or Tito, and Manantial de las Aguas Frias. The caves were explored during the 1980 by different caving groups, and finally one after the other connect to the system. With the connection of Juan Nieves to Encantado, the cave system reached a total length of 16,910 m, which makes it currently the longest cave of the island.

The cave has numerous sumps and vertical sections, and it is definitely not a cave for tourist visits. Nevertheless, it seems the cave is guided on cave trekking tours, at least a more harmles section.
