Organ Pipe National Monument is like Big Bend National Park in one respect. You really have to want to go there. It’s on the Mexican border and only two roads access it. One is paved and goes to a small border crossing. The other is gravel and connected the ranches that used to operate in the area with the border to the south and the town of Ajo, near our campsite, to the north. We chose to return to camp on the gravel road.
