Cuevas del Águila, Limestone cave in Ramacastañas, Spain.
Cuevas del Águila is a limestone cave near Arenas de San Pedro featuring extensive underground chambers shaped by water erosion in crystalline rock formations. The cave system stretches across paved pathways that wind through multiple caverns positioned above the Arenal and Avellaneda rivers.
Local residents discovered the cave system in 1963 after observing steam rising from a small opening on Cerro de Romperropas. This finding opened up one of the region's most remarkable natural formations to public access.
Visitors walk through chambers where mineral deposits create striking colors across the walls and formations. The different hues throughout the cave offer a natural display that draws people to explore underground.
The cave maintains consistent temperatures year-round, so layered clothing is a smart choice for comfort. The well-developed pathways are straightforward to walk through without requiring any special equipment or prior experience.
Scientists study the stalagmites in this cave to gather information about ancient climate changes and glacial periods. This research contributes to understanding how the environment shifted thousands of years ago in the nearby Gredos Mountains region.
