Welcome to the Green Desert!

Organ Pipe Cactus National Monument was set aside on April 3rd, 1937 for future generations as an exemplar of the Sonoran Desert. This natural area is home to an abundance of life: quirky cacti, talkative birds, whispering springs with desert fish, and so much more! The life found in the Sonoran Desert has adapted to this land of extremes in a multitude of ways, each playing a role in this magical landscape. Gentle spring rains, turbulent summer skies, and the penetrating sun set the stage as volcanic layered mountains, ribbons of washes and expansive valleys act as the backdrop for this International Biosphere Reserve.

Explore the desert wilderness hiking through hidden washes, adventuring off on a scenic drive, or relaxing and the monument's campgrounds. Learn what you need to know before you go!
