Mallos de Riglos, Vertical rock formations in Aragon, Spain.
The Mallos de Riglos consists of red conglomerate rock walls that rise approximately 300 meters above the village, creating vertical cliffs visible from distant viewpoints. The formation spans a large area with varying heights and structural features suitable for different activities.
The structure formed over millions of years through sedimentary processes that built up compressed rock layers and natural materials. This geological development shaped the present-day landscape and remains an example of how natural rock formations develop.
The formations serve as a gathering place for climbers worldwide, who come together each year and help shape the mountain traditions of the region. The site has become a hub where climbing culture intertwines with local Aragonese heritage.
The train to Riglos station or driving from Pamplona through mountain roads are the main ways to reach the site, with parking available at the access points. Sturdy footwear and water are recommended for anyone exploring the rock formations.
The cliffs house one of Europe's largest griffon vulture colonies, with hundreds of these birds nesting in the crevices. Watching these powerful raptors soar along the rock faces offers an unforgettable experience of their flight mastery.
