Rio Seco Natural Park

Rio Seco Natural Park — A Hidden Gem of Alicante Province

Rio Seco Natural Park, located in the province of Alicante, Spain, is a unique natural haven known for its rich ecosystems, diverse flora and fauna, and striking geological formations. The park stretches between the towns of Orihuela and Pilar de la Horadada and takes its name from the dry riverbed of the Rio Seco ("dry river" in Spanish) that runs through it. Its natural beauty and ecological significance make Rio Seco a popular destination for eco-tourism and outdoor recreation.

Geography and Natural Features

The park is named after the intermittent river Rio Seco, which fills with water during the rainy season but often dries up completely in summer. These alternating wet and dry periods create a unique environment that supports a wide range of ecosystems. The riverbed is mostly composed of sandstone and limestone, giving the landscape a distinctive character. In some areas, you can observe natural "sculptures" formed by erosion over thousands of years.
