28-NOV-1964 connection to the Gruta da Tapagem discovered.
1969 Parque Estadual de Jacupiranga founded.


Caverna do Diabo (Devils Cave) is a well developed and beautiful cave with extraordinary speleothems. It is the longest cave of the state São Paulo, but you will find it in the official lists under the name Gruta da Tapagem (Cave of the Hedge). The reason is easy, two different entrances to the same cave system were known for a long time. Not knowing about the connection, the locals gave both of them different names. The connection was discovered in 1964 by the cavers Michel Le Bret, Philippe Goethals, Caille Goethals, Luiz Guilherme Assumpção (Méca), and Sérgio Audino

Tapagem Cave is a river cave developed in the dolomite marble karst of the Serra do André Lopes. This karst has very few caves, so the Tapagem Cave is an anomalous feature. It is formed by the Tapagem River which sinks at the end of a blind valley and flows underground to the Ostras River. The catchment area of the sink is much bigger than the karst area, a lot of water flows into the cave system and is the reason for the cave development. So you could say it is the result of contact karst: water draining on the surface of insoluble rocks and vanishing underground into a cave as soon as it reaches the soluble rocks.
