[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.

[1] This gives rise to dramatic ridges and steep peaks that form small plateaus, often with very prominent, nearly vertical cliff faces.

Flora is characteristic of mixed pine-oak forests in the mountains, dominated by trees including the Pinus cembroides and encino, and of scrubby, arid grasslands at lower elevations.

Several growing human settlements are very close to the park, many of which are dedicated to agriculture and livestock ranching and have caused serious deterioration of surrounding natural ecosystems in certain areas.

[6] Sierra de Órganos is frequented by nature lovers as well as extreme sports enthusiasts, as the steep peaks and slopes lend themselves to rock climbing.

While some areas are suitable for camping, most of the park lacks basic services and provisions such as drinking water; these must be obtained in nearby villages.
