Rancho de la Osa
Sasabe, Arizona
Rancho de la Osa is two and a half hours from the Organ Pipe Cactus National Monument, a UNESCO biosphere reserve and the only location in the United States where the Organ Pipe Cactus grows in the wild. Dozens of hiking trails plus scenic roadways make for a wonderful taste of the Sonoran Desert and perhaps a chance to see the endangered Sonoran Pronghorn and other plant and animal species native to the area.
