The two formations are composed of Miocene-era conglomerate and sandstone.
El Picuezo is the larger of the two, while La Picueza sits slightly lower in elevation.
They are remnants of a former geological shelf that retreated due to thousands of years of wind and water erosion.
The pinnacles are a prominent feature of the 'Ruta del Cidacos' landscape in La Rioja.
Despite their size, the narrow bases of the rocks give them a precarious, gravity-defying appearance.
El Picuezo y la Picueza are two distinctive, towering sandstone pinnacles located in the municipality of Autol, La Rioja, Spain. These natural rock formations, created by differential erosion of the Cidacos River basin, reach heights of approximately 42 meters for the taller formation and 27 meters for the shorter one. The local name stems from the Spanish word 'picuezo,' historically referring to a conical stack of grain or a stone peak. Geologically, they serve as a landmark showcasing the sediment deposition patterns of the Ebro Basin. The structures are situated on the outskirts of the village, integrated into the local landscape of hills and farmland. They are officially recognized as natural monuments within the Riojan geography.
The elevated dirt path leading toward the formations provides the best angle to capture both pillars in a single frame.
Wear sturdy walking shoes to navigate the loose gravel and uneven terrain surrounding the base.
Bring water, as there are no amenities or shade structures directly at the site.
The site is accessible year-round, but visit during cooler parts of the day to avoid intense sun exposure.
Do not attempt to climb the formations, as the sandstone is fragile and climbing is prohibited to preserve the site.
