A couple of hours south of Tucson lies Organ Pipe Cactus National Monument. The southern boundary of the park is the international border with Mexico. The visitor center is about six miles from the border crossing station on Arizona Route 85.
This park has a broad variety of cactus species, including Saguaro, Ocatillo, various types of Cholla, and obviously the Organ Pipe. This is the only place in the United States where the park’s namesake cactus can be found naturally.
