Diablo Canyon was formed by Diablo Wash. These washes are formed by the flow of rainwater from the mountains, and allow a wide variety of plants and animals to thrive in this thin ribbon of land in the desert. There are also picnic tables here at Diablo Canyon to enjoy a nice relaxing lunch.

At point 13 along the drive is Arch Canyon. Her you will see an arch that was formed by the freezing and thawing ow ice and by the forces of the wind. The arch is 36 feet high, 90 feet wide and over 720 feet above the road. You can hike up to the arch if you want too. The hike to get close to the arch is not too bad but after a certain point the trail ends and the route is very steep, slippery and is at your own risk.

The Ajo Mountain Drive winds through the bajadas, foothills and peaks of the Ajo Mountains. The Ajo were formed 15 to 25 million years ago by periods of volcanic activity. The colorful bands you may see in some of the photos are tuff which is compressed volcanic ash.

One good way to see a lot of the attractions in the park is to take the Ajo Mountain Drive. The drive is 21 miles along a graded dirt road. The road is fine for passenger cars as long as you drive carefully. There are 22 stops along the way wher you can explore further and learn more about the area. Two of the stops include the Ajo Mountain Arch and the Estes Canyon Trail. A booklet that will tell you about the stops along the drive can be purchased for $1 at the Visitor's Center. I recommend it.

Your first stop at the park should be the visitor's center where you pay the entrance fee and get brochures and other information to help you enjoy the park. The visitor's center has a nice museum, a nature trail out the back, and graet views. The memorial at the front reminds you of the dangers in the area. He was killed by drug smugglers.

Of course the park is named for the Organ Pipe Cactus but there are also other types of cacti growing here. You can also see the mighty Saguaro, the Prickly Pear Cactus, and the Cholla (not pictured).

The best place to see the Organ Pipe Cactus (Stenocereus thurberi) is in the Organ Pipe Cactus National Monument. There are other places to see them but they are most abundant here. Keep in mind this is the desrt and it is near the border so exercise caution during your visit. Drink lots of water, stay on established paths and avoid any smugglers you see along the trails. Also beware of the rattlesnakes, scorpions and other wildlife.

If you do not justwant to drive, you can stop to see the arch at the Arch Canyon. It is short walk from the parking there to get a good view on it. Watch for rattle snakes!
There is a picnic place aswell!

Just opposite of the Visitor Center the start of the Ajo Mountain Drive is located. It is a 20 miles drive on a gravel road through the desert. I recommend this loop as it brings you deep into the park with very beautiful sights on the mountains.
Take care that you have enough gas in your tank, there are not too many people driving and it probably would take some time until someone could help.
See the weblink below for further information.
