Pulpí Geode, Giant crystal cave in Pilar de Jaravia, Spain.
The Pulpí Geode is a natural crystal-filled cave with large, translucent selenite growths covering the walls of the underground hollow. The inner chamber, located roughly 50 meters below ground within an abandoned mine, displays a system of crystal-lined rooms.
This crystal formation was discovered in late 1999 by mineralogists from Madrid while exploring the interior of an abandoned silver mine that operated from 1840 until the Spanish Civil War. The chance finding turned this underground site into a research focal point.
The name refers to the nearby town of Pulpí, and the site has become a symbol of the region's mining heritage since its discovery. Visitors walk through narrow, crystal-filled chambers that reveal how minerals grow naturally over time.
Access requires advance reservation, as openings are limited and pathways are narrow. Visitors should prepare for cool, dark conditions and wear comfortable shoes with good grip to safely navigate the crystal-lined chambers.
The large selenite crystals in this cave formed over an extremely long period through processes between groundwater and mineral deposits. This natural phenomenon makes the site a rare example of a well-preserved underground crystal formation for geologists and mineral enthusiasts.
