Cerro del Hierro

Cerro del Hierro is a karst formation in the Sierra Norte of Sevilla featuring limestone rock with iron deposits spread across roughly 120 hectares. The landscape consists of interconnected corridors, sinkholes, caves, and natural stone spires that draw climbers from across the region.

Iron mining at this site began during Roman times and continued through the centuries. In the 1800s, the Scottish company William Baird Mining took over operations and shaped the landscape as it appears today until activities declined mid-20th century.

The name refers to the iron deposits that shaped this landscape for centuries through extraction activities. Today, visitors can observe how mining left its mark on the terrain and the way people interact with this transformed natural space.

This site offers over 120 climbing routes of different difficulty levels and serves as the main climbing destination in Sevilla province. Wear sturdy footwear and watch for uneven paths and cave openings that appear suddenly throughout the landscape.

During autumn and winter rains, temporary ponds form throughout the karst landscape, attracting rare amphibians, marsh owls, and black storks. These seasonal bodies of water transform the area into an unexpected wildlife refuge that catches many visitors by surprise.
