Pima County

Shaped by the Santa Cruz River corridor, Pima County grew into one of Arizona’s largest counties. Its western reaches lie in the Sonoran Desert, where saguaro cacti, wide basins and isolated mountain ranges define the terrain. Parts of both Saguaro National Park and Organ Pipe Cactus National Monument fall within the county, while much of the west belongs to the Tohono O’odham Nation. Tucson, the county seat, adds a different dimension through the University of Arizona and food traditions shaped by Mexican and Indigenous influences.
