Buenos Aires National Wildlife Refuge
An hour southwest of Tucson in the Altar Valley are 118,000 acres of protected and managed Sonoran grasslands. This is the major part of the Buenos Aires National Wildlife Refuge. 

 A few miles east, near the town of Arivaca, is the Arivaca Cienega (wetlands) and Arivaca Creek. This critical riparian corridor is also managed by the Buenos Aires NWR. 
The Baboquivari Mountains which flank the grasslands to the west are the western-most of the sky islands of southeastern Arizona.

Deep in the heart of these mountains beneath the tower of Baboquivari Peak is Brown Canyon. Here the Buenos Aires Refuge is charged with protecting and preserving a sky island canyon ecosystem. This is the location of the Environmental Education Center Lodge.

The Refuge Headquarters and Visitor Center are in the old Buenos Aires Ranch buildings and offer the visitor exhibits, information, a book shop and shady grounds for enjoying the "good airs" and expansive vistas.
The diversity of wild-lands embraced by these three units of the Buenos Aires Refuge make it a particularly important tract of Sonoran ecosystems.
The refuge operates a vigorous seasonal volunteer program. From late October to April participants stay in refuge facilities and help with the refuge programs and maintenance. For more more information contact the refuge at 520 823-4251.
Come out! The office and Visitor's Center is open from 7:30AM to 4:00PM seven days a week excepting federal holidays.
