Sierra de Órganos National Park (Spanish: Parque Nacional Sierra de Órganos) is a national park in Mexico, located in the northwest corner of the municipality of Sombrerete in the state of Zacatecas, near the border with Durango. The park is known for its diverse aridland ecosystem and towering rock formations of the Sierra Madre Occidental, which are reminiscent of organ pipe cacti or the pipes of the musical instrument, from which the park takes its name.[2] In addition to conifer forests in the highlands and xerophilous scrub in the lowlands, Sierra de Órganos is a refuge for several species of animals endemic to the region and others in danger of extinction. It is a popular area for recreation, including hiking and cycling, and for its scenery and landscapes.[3]
