Picacho El Oregano, Mountain summit in Nuevo León, Mexico

Picacho El Orégano is a summit reaching 2,250 metres above sea level in the municipality of Santa Catarina, Nuevo León, about 8 kilometres south of the municipal seat. It belongs to the Sierra Agua del Toro, the Sierra Madre Oriental and the Cumbres de Monterrey National Park, and geologically to the Peyotillos anticline. The peak is surrounded by the Cañón de la Huasteca, Cañón de San Judas, Anticlinal Agua del Toro, Cañón de Guitarritas and Sierra de San Urbano.

Historical documents record the summit as Pico del Gavilán, probably referring to the Gavilanes Indians who once lived in these mountains. Locals call it Picacho El Orégano, while local mountaineers know it as Aguiluchos del Sur, after an old climbing club called Aguiluchos. The peak lies in the municipality of Santa Catarina, about 8 km south of the municipal seat, within the Sierra Agua del Toro and the Cumbres de Monterrey national park.

At the foot of the peak, beside Cañón de Guitarritas, lies Loma Alta, which the Huicholes regard as the place of creation. They travel there each year to hold rituals honouring life, rain, the sun and Tatewari, a fire deity.

The ascent gains about 1,440 metres of elevation over difficult terrain and demands good fitness. Climbers favour autumn and winter; the ascent is not recommended in summer. The summit reaches 2,250 metres above sea level, and the peak lies roughly 8 kilometres south of Santa Catarina within Cumbres de Monterrey National Park.

The summit is known as Aguiluchos del Sur within climbing communities, a name rarely found in official maps. This regional label shows how local climbers use different identities for the peak based on their own traditions.
