Basic Information

Welcome to Organ Pipe Cactus National Monument!

This 330,000 acre monument was set aside in 1937 to preserve a pristine example of Sonoran Desert. 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. Visitors come ready to enjoy the trails and scenic drives, the star-lit nights and the sun-filled days!

Arizona highway 85 is the main entrance into the monument. The highway and the road into the campground are the only paved roads in the monument; all other roads are dirt and gravel, and some may require a high clearance, 4-wheel drive vehicle to explore - most noteably North Puerto Blanco Drive. Check at the Kris Eggle Visitor Center for road conditions throughout the monument and on our Alerts & Conditions page.
