The microclimate within the mine can be up to 10 degrees Celsius cooler than the surrounding surface area.
It is a protected Natural Monument under the regional government of Extremadura.
The mine consists of four distinct levels, with the deepest reaching approximately 90 meters below the surface.
The mineral extraction at La Jayona primarily focused on iron ores, specifically hematite and magnetite.
Abandoned tunnels provide critical habitats for at least 11 different species of bats.
The site features a permanent small pond at the bottom, which serves as a vital water source for local wildlife.
Industrial activity officially ended in 1921 due to the lack of profitability compared to larger mining operations.
The geological structure allows visitors to see clear transitions between limestone and iron-rich ore deposits.
Mina La Jayona is an abandoned iron mine located in the Sierra de la Jayona, transformed into a protected geological and biological sanctuary. The site is a Natural Monument featuring a unique microclimate that fosters a distinct Mediterranean forest ecosystem within its deep excavation pits. Visitors descend into a series of open-air craters and tunnels that reveal colorful mineral veins and geological stratification. The mine ceased industrial activity in 1921 after decades of extraction, leading to a natural process of abandonment that allowed indigenous flora and fauna to reclaim the space. It is home to multiple bat species that utilize the old underground galleries for hibernation and breeding. The site is characterized by significant temperature variations between the surface and the bottom of the mine.

Wear sturdy, closed-toe hiking footwear as the terrain consists of uneven, rocky paths.
Bring a light jacket even in summer, as the temperature drops significantly once you descend into the pit.
Book guided tours well in advance through the official portal, as access is strictly controlled for conservation.
Attempting to visit without a pre-booked guided appointment, as the site is gated and inaccessible to the general public otherwise.
Closed on Mondays and Tuesdays. Access is restricted to guided tours only.
Strictly follow paths, do not touch rock walls to protect mineral deposits, and maintain silence to avoid disturbing bat colonies.
