Buenos Aires National Wildlife Refuge in southern Arizona was established in 1985 for the reintroduction of masked bobwhite quail and the restoration of natural landscapes and their native wildlife, including the Sonoran Pronghorn. The 118,000-acre refuge lies in a broad Altar Valley between the Baboquivari Mountains, with their prominent main peak in the west, and the lower San Luis Mountains to the east. In the 1850s, Pedro Aguirre, Jr. built a homestead here in 1864 and named it Buenos Ayres, or "good air," because of the constant winds. His ranch changed hands several times before being purchased to form today's wildlife refuge. The refuge's visitor center is located in the adobe ranch house.
The refuge has over 80 designated campsites identified by a numbered sign. Camping is free and allowed for 14 days in a 30-day period, but only in the designated campsites. Most campsites have a fire ring/grill. Site sizes vary from a single vehicle to large enough for multiple RVs and trailers. Most are suitable for tents.
Fuel and limited supplies are available in the nearby small towns of Sasabe and Arivaca.
State Tank - Rock Tank Loop combines roads 213 and 249. The loop begins and ends near the visitor center and Aguirre Lake. While narrow on the western ends with grass in the middle, the trail widens out on the east. Campsites 68 and 68A sit on the northern portion of the loop. 68 is a large site capable of accommodating several trailers. 68A is a small one-vehicle site off a small spur with excellent views. Both sites have a metal fire ring. When mapped, the refuge was removing invasive mesquite trees near the trail to restore the open native grasslands.
