Welcome to Organ Pipe Cactus National Monument
This 517-square-mile park was set aside in 1937 to preserve a pristine example of Sonoran Desert Habitat. Organ Pipe Cactus National Monument preserves the northern-most natural habitat of the Organ Pipe Cactus, as well as amazing examples of desert plants, animals, geology, and human history. Be ready to enjoy the trails and scenic drives, the star-lit nights and the sun-filled days. Keep yourself safe by knowing what to expect from a desert wilderness.

Always check the weather and bring the appropriate clothing and other essentials for your visit. You might need to become more familiar with accessibility information or the safety rules for you and your pet.
