Organ Pipe

Organ Pipe Cactus National Monument celebrates the life and landscape of the Sonoran Desert. Here, in this desert wilderness of plants and animals and dramatic mountains and plains scenery, you can drive a lonely road, hike a backcountry trail, camp beneath a clear desert sky, or just soak in the warmth and beauty of the Southwest. The Monument exhibits an extraordinary collection of plants of the Sonoran Desert, including the organ pipe cactus, a large cactus rarely found in the United States. There are also many creatures that have been able to adapt themselves to extreme temperatures, intense sunlight and little rainfall.

This is a showcase for creatures who have adapted themselves to the extreme temperatures, intense sunlight, and little rainfall that characterize this Southwest region. Twenty-six species of cactus have mastered the art of living in this place, including the park’s namesake and the giant saguaro.


National Parks and National Monuments are both administered by the National Park Service, and are identical in their function and purpose. Both are types of federally protected lands, and share the common goal of preserving and protecting significant natural and cultural resources.

The major difference between a national park and a national monument is the manner in which they are created. A national park is established through an Act of Congress, and the land may originate from a variety of sources, including public and private land. A national monument is established by Presidential proclamation, and this land is to be taken only from existing public (federal) ownership.
