Organ Pipe Cactus National Monument
Look closely. Look again. The sights and sounds of Organ Pipe Cactus National Monument, an International Biosphere Reserve, reveal a thriving community of plants and animals. Human stories echo throughout the Sonoran Desert, chronicling thousands of years of desert living. A wilderness hike, a scenic drive, or a night of camping will expose you to a living desert abounding with hidden life.
