Pozo Airón, Waterfall in Pereña de la Ribera, Spain

Pozo Airón is a waterfall in Arribes del Duero Natural Park featuring three cascades that plunge roughly 50 meters into a deep canyon between Salamanca and Zamora provinces. The water flows through the Arroyo de los Cuernos stream within a Mediterranean microclimate zone dotted with olive trees, almez, junipers, and rockroses.

The waterfall lies in the municipality of Pereña de la Ribera, in the province of Salamanca, Castile and León. The surrounding area has a Mediterranean microclimate with vegetation typical of eastern Spain, such as olive trees, hackberry, junipers and rockroses.

The name Pozo Airón is linked to the spray thrown up where the water strikes the rock, a haze that can be seen from the paths above the gorge. The surrounding slopes hold olive trees, hackberry, junipers and rockroses, a Mediterranean plant cover unusual for this part of Salamanca.

The site is accessible via two hiking paths from either Masueco or Pereña de la Ribera, each offering different difficulty levels. Autumn brings higher water flow from seasonal rainfall, though trails may be wet and slippery during this time.

The name Pozo Airón is often linked to the mist that rises when the water hits the gorge, but the sources also place the fall in a Mediterranean microclimate unusual for this part of Salamanca: olive trees, hackberry, junipers and rockroses grow around it, vegetation more typical of eastern Spain.
