18-SEP-1954 members of the Sociedad Espeleológica de Cuba (SEC) explored the cave, lead by Dr Antonio Nuñez Jiménez.
05-JUN-1989 declared National Monument by resolution #59.
1994 opened as a show cave.


With a length of 47 km this is the second longest cave in Cuba. It is formed on 7 levels with a vertical range of 89 m and is the main drain for the 400 m high Quemado Mountain range. The entrance passage are enormous, up to 10 to 20 m wide and during the Cold War years they were used by the military. Consequently many of the speleothems near the entrance show signs of wear.

Tourists are given helmets and caplamps. This save having to install electic light and the problems of lampenflora.

The Gran Caverna de Santo Tomás was named after the stream of Santo Tomás, which formed many of the huge passages.
