How Big is Organ Pipe Cactus National Monument?

Ajo, Arizona

This National Monument totals 517 square miles of the Sonoran Desert. It is named after the organ pipe cactus, which branches look similar to an organ pipe. This is the only area in the US where you can find the organ pipe growing wild!

The senita cactus is another cactus in the US that can only be found in the monument. This cactus looks very similar to the organ pipe, but the main difference is that you will find a thick bunch of spines near the top of its branches.

According to the National Park Service, Organ Pipe National Monument “was created in 1937 as a way to preserve a representative area of the Sonoran Desert. The new monument was part of a movement in the National Parks to protect not just scenic wonders but also the ecological wonders of the country. Over 75 years later, Organ Pipe Cactus is now one of the best-preserved examples of the Sonoran Desert wilderness.”

What To See in Organ Pipe Cactus National Monument

Ajo Mountain Drive

This 21-mile loop drive is the most popular drive in Organ Pipe Cactus National Monument, but thankfully not crowded. This is a well-maintained dirt road with some sections of the washes paved. Make sure to stop at the Kris Eggle Visitor Center to scan the QR code for a free Ajo Mountain Road Guidebook. This book explains the landscape, cacti, and history of the park.

Estes Canyon Hike

This hiking trail is a 3.1-mile loop, with an elevation gain of 865 feet. There is an optional one-mile spur trail called Bull Pasture that will lead you to a viewing point where you can see Mount Ajo, the highest peak in the monument at 4,808 feet.

Puerto Blanco Drive

Puerto Blanco Drive was reopened in 2014 and provides access to the Pinkley Peak Picnic Area, Red Tanks trailhead, Dripping Springs, and Quitobaquito Springs. Take your time on this loop trail to stop and read the informational signs on the ecology of the Sonoran Desert. If you get to Organ Pipe Cactus National Monument early, we recommend doing this loop first.

According to the monument’s website, “the North Puerto Blanco and South Puerto Blanco Loop is 41 miles in total and will take roughly 4 to 5 hours round-trip. High clearance vehicles are recommended beyond Pinkley Peak.”
