Every small place and detail of the Organ Pipe Cactus Monument has a very special meaning and history to it. There have been people making their marks amongst this National Monument for over a thousand years. They’ve left behind their pieces of art in the forms of pottery, rocks, and many other forms. The National Monument itself remains so untouched that even the trails carved into the dirt many years ago can still be seen. Archeologists have recovered many different important pieces left behind from as far as 1,600 years ago.
The National Monument got its name from the large stands of Organ Pipe Cacti that can be found within the deserts. The species of cacti has also gotten its name from its resemblance to the pipe organ instrument. It wasn’t until 1977 that the Organ Pipe Cactus National Monument was declared a Monument. A year prior, it had been designated an International Biosphere Reserve.
As beautiful as the Organ Pipe Cactus National Monument is, there’s no lying about its somewhat dark history. For the longest time, the National Monument unfortunately faced a lot of dangerous activities and was considered one of the most dangerous National Parks. This was extremely unfortunate considering that the Organ Pipe Cactus National Monument was located in one of the most thriving ecosystems in the United States. Illegal activity was often encountered in these areas. Visitors were advised to be extremely cautious when traveling through hiking trails and scenic drives. Armed park rangers also had to escort any travelers who were brave enough to go down the hiking trails.
However, since these occurrences have occurred, there have been actions taken to help prevent any possible unwanted encounters. Nowadays, the National Park is safe to travel through as long as you’re in groups, staying close to park rangers, listening to safety protocol, and listening to safety tips that are enforced. Now more than ever is a great time to visit the National Monument, as its safer than its ever been.

Very nice site, but note this site is for off road vehicles not rv’s. From the north it was 33 miles of 4×4 use and lots if scratches on the truck and camper. I was not able to continue south so without a jeep or the likes it is only accessible from the north (Tacna). It was pretty but id never go back without a jeep. Absolutely no Verizon service at all.

My local hosts told me to look for hills like cow pies. Rocalla street leads out of town on a narrow dirt road, up and down the washes and suddenly opens up to a pleasant camping area surrounded by saguaro and lumpy cowpie hills. Very quiet and scenic. Great stars even though Ajo is Only a mile away.

Best Review:
Nice spot with about 6 or more sites on loop thru drive with the concrete slab closest to main wash. Small wash with some soft sand to cross next to slab site, no problem for 2wd if you keep moving. There are a couple of larger sites that can hold 2-3 class A size RVs easily. Several smaller sites too. We parked in one of the larger upper sites and was able to get 13 OTA TV channels, pointed to the east.

Best Review:
It’s easy to find, and other than navigating around the “paths” throughout the area to find a spot, the access is easy as well. While it is an area near the Mexico border we experienced no issues and felt completely safe. There were a lot of other camper scattered about, but due to the large amount of space, we did not feel crowded and you could hardly tell when someone did run a generator. It is quite close to the main highway unless you choose to drive way far back in; however there was no road noise at all.

Best Review:
Very dusty dirt parking lot, with some pull-through sites. I was here during the annual Fiddler’s Contest, so there were a LOT of RV’s out behind the club house. Lots of cars going back & forth, thus the endless dust clouds. But it is quiet at night – unless an RV fires up the generator.

We stayed one night at this Organ Pipe National Monument campsite while passing through. There are designated campsites past the arena but no fees. Meet a couple who said they had a permit to camp there long term but there was no fee. It was very primitive but felt safe. About 6 other campers there, most were there long term. Everyone gave each other plenty of elbow room. Wild burros in the area. We heard them in the distance but never saw them except for tracks and droppings.
Amenities:

Don’t know if it changes during the year, but this is a no fee site for camping. Officials have stopped to check the toilets and no fees are mentioned and there is no fee station.
