About Organ Pipe Cactus
Pipe Organ Cactus National Monument preserves 330,689 acres of the Sonoran Desert in southern Arizona right on the Mexican border. It is named after the the Saguaro Cactus whose multiple trunks resemble the pipes of an organ. A surprising variety of desert plants cover the desert, including the saguaro cactus, prickly pear cactus, ocotillo and creosote bushes.
California Route 85 passes through the middle of the monument, and southward into Mexico. A handful of dirt roads and several trails offer a closer look at the desert, including Alamo Canyon Road, Ajo Mountain Road and Puerto Blanco Road.
