The paintings represent the Solutrean and Magdalenian periods of the Upper Paleolithic.
A distinctive feature is the 'Fish' painting, considered one of the most accurate prehistoric depictions of aquatic life.
Because of the humidity and delicate state of the paintings, the cave has no electrical infrastructure.
The cave contains a large gallery known as the 'Hall of the Bats'.
No artificial ventilation is used, allowing the cave's microclimate to remain stable for the preservation of the art.
The cave has never been commercially exploited with permanent walkways or stairs, keeping the terrain mostly natural.
Cueva de la Pileta is a subterranean archaeological site in the Sierra de Grazalema containing Paleolithic cave paintings dating back over 20,000 years. The cave was discovered in 1905 by José Bullón Lobato while he was searching for bat guano to use as fertilizer. It features a sequence of rock art including charcoal drawings and red ochre paintings of horses, deer, and fish. The site is notable for retaining its natural state, as it contains no artificial lighting and visitors are guided by hand-held lamps. Geological formations include significant stalactites and stalagmites within a multi-level limestone gallery system. The site remains under the stewardship of the original discoverer's descendants, who provide the guided tours. It is officially protected as a Bien de Interés Cultural in Spain.
