The Cascada de Orós Bajo, nestled in the Barranco d´os Lucas at the beginning of the Valle de Tena, is a hidden gem in the Huesca Pyrenees. Unlike other equally stunning spots that require a long hike to reach, like the Arco de Piedrafita or the Cola de Caballo, this waterfall is just a 20-minute walk away. The turquoise waters and unique rock formations make it a must-see destination for nature lovers looking for a quick adventure in the Spanish mountains.
