Organ Pipe Cactus National Monument is a U.S. National Monument and UNESCO biosphere reserve located in extreme southern Arizona which shares a border with the Mexican state of Sonora. The park is the only place in the United States where the Organ Pipe Cactus grows wild. That is the official description. “Extreme southern Arizona” means we drove 2 1/2 hours south of Tucson to the middle of nowhere and camped 5 miles from the Mexican border. Don did have to do some convincing to get Leslie to go camping in a campground that had no electricity or water (and no phone signal), but it was great. The campground was very nicely done (the last picture shows the camper in our spot in the campground). We had perfect weather, cool nights and day time temps of 80 degrees, and as you can see from the pictures, the park is absolutely beautiful. It was also nice to “unplug” and just enjoy nature.
