      This 21-mile drive, accessible by any vehicles up to 25 ft, is the most popular way to explore Organ Pipe Cactus National Monument. Pick up the free guidebook from the Kris Eggle Visitor Center and allow at least 2 hours to complete the loop, which takes in 18 stopping points. As well as the distinctive cactus from which the park takes its name, you will also see examples of the many other plants that flourish in the Sonoran Desert including saguaro, prickly pear, jojoba, mesquite, cholla, and ocotillo.

      If you go:
      Much of the park was closed in 2003 due to high levels of illegal border activity. However, large areas were re-opened to the public in September 2014 following a decision to manage the risk through education rather than closure.
