Convenient spot close to Organ Pipe Cactus National Monument. I got a little confused trying to find this spot at night, but once you find where the dirt road passes through the gate there are plenty of places to camp right there. There was only one other group there in October, but I would assume it gets more crowded during the winter months. It's a little close to the highway, so you will hear some cars passing by, but it's not too bad.
