Introduction

A U.S. National Monument as well as a UNESCO biosphere reserve, Organ Pipe Cactus National Monument is located in southern Arizona, sharing a border with the state of Sonora in Mexico. The main attraction of the park are the organ pipe cactus, which grow wild within its confines. You can also view a number of other types of cacti, include the stately Saguaro and desert flora. The National Monument encompasses 517 square miles; land for the Monument was donated during prohibition to the federal government by the Arizona state legislature, with the knowledge that the north-south road would be improved and it would be easier to import contraband alcohol from Mexico.

Organ Pipe Cactus National Monument is one of the few areas north of the Mexican border where its namesake cactus grow. Included in the preserved area are gentle valleys and craggy mountains, with more than 90% of the land designated as wilderness. Hiking, camping and scenic drives are popular things to do for those exploring the park.

A visit to the National Monument will introduce you to desert life and offer you the chance to view some incredible scenery as you take in the area’s natural beauty.
