About this city
Also known as: The Gateway to Organ Pipe
Ajo is a historic former copper mining town located in Pima County, Arizona, deeply nestled within the Sonoran Desert. Positioned along State Route 85, it serves as the primary southern gateway to Organ Pipe Cactus National Monument and the Mexican border. The town's heart features an incredibly beautiful Spanish Colonial Revival-style plaza dating back to 1917, framed by white stucco buildings, elegant arches, and a vibrant community park. Surrounded by millions of acres of pristine desert public land, Ajo has transitioned from its rich industrial mining roots into a peaceful, thriving haven for desert explorers, artists, and retirees.
