Organ Pipe Cactus:

A Sonoran Desert Treasure

Scenic drives, hiking and camping await adventurers!

Life Abounds in the Sonoran Desert. The sights and sounds of Organ Pipe Cactus National Monument, an International Biosphere Reserve, reveal a thriving community of plants and animals. Human stories echo throughout this desert preserve, chronicling thousands of years of desert living. A scenic drive, wilderness hike or a night of camping will expose you to a living desert that thrives.

Organ Pipe Cactus National Monument exhibits an extraordinary collection of plants and animals of the Sonoran Desert. This is a showcase for creatures who have adapted themselves to the extreme temperatures, intense sunlight, and little rainfall that characterize this Southwest region. Thirty-One species of cactus have mastered living in this place, including the park's namesake and the giant saguaro.  The monument is an outstanding natural preserve where one of the of the Earth's major ecosystems survives almost unspoiled.  Recognizing its significance, the United Nations in 1976 designated the monument as an International Biosphere Reserve. 

The epic skies 

No matter if it's day or night, the sky above Organ Pipe is always putting on a show. Pastel sunrises start to creep over the horizon before illuminating the spikes on the saguaro cacti in your campsite.  In the evening race up the Desert View Trail to catch the super saturated sun setting over Mexico. Once the sun goes down, gaze at the Milky Way stretching over the park, or go to a night sky program at the amphitheater to see the nebula in Orion's sword.

The trails are gorgeous and empty.

The Sonoran Desert is nicknamed the "green desert" for its lush vegetation. Park trails traverse washes, climb hillsides, and weave through dense forest of cacti. You might see another person...maybe.  But for the most part, this wonderland will be all yours.

Peer into Mexico from the Estes Canyon Trail, or check out the Victoria Mine. The views will be worth it.

Impeccable Campground

Twin Peaks Campground sets the standard for park camping. Every site has a great view, the facilities are impeccably clean. The sites have groomed gravel pads for tents and level concrete pads for RVs, which means you don’t have to worry about camping on a slope. While there aren’t any fire rings, there are BBQ stands and picnic tables.

In addition to nice flushing toilets, this campground also had free large showers. However, they are heated with solar power, so plan on taking a shower after the water has had a chance to warm up.

Electric and water hookups are not available.  Water spigots are available throughout the campground.  There are utility sinks at the restrooms.  An RV dump station is nearby.

Quiet Hours are from 10:00 p.m. to 6:00 a.m. Generator use is always prohibited in sites 113 - 208.
