Salto de Bierge is a prominent waterfall and river bathing area located on the Alcanadre River at the gateway to the Sierra de Guara Natural Park. The site features a historic dam and weir that creates a large, deep pool utilized for recreational swimming. The area serves as a focal point for visitors exploring the canyoning routes of the Huesca province. The surrounding landscape consists of sedimentary limestone cliffs typical of the Somontano de Barbastro region. Access to the riverbed has been strictly regulated in recent years due to environmental protection measures and visitor safety concerns. The site operates as a regulated point of entry for those seeking to enjoy the natural pools beneath the masonry weir.
