Arizona, Organ Pipe Cactus National Monument.  The monument is located along the US/Mexican Border, south of Ajo, west of Tucson, and east of Yuma.  It's quite a remote area.  Access is via single lane highways.   The roads can be very rough at times and challenging for large RV's.


From the NORTH: follow Arizona Hwy 85 through Ajo and Why. The Monument is 22 miles (35.4 km) south of Why on the right side of the highway. 

From the EAST: follow Arizona Hwy 86 to Why, then turn south on Arizona Hwy 85.  The monument will be 22 miles south on the right side of the highway.  

The Campbase map tab provided here is accurate for the location of the Cris Eggle Information center.  It's located approximately 20 miles inside the park.  That's 20 miles from Why, Arizona. 


Organ Pipe Cactus National Monument has tent and RV camp spots.  Most spots are large pull through camp spots.  Big rigs up to approximately 45 feet can be accommodated.  This is dry camping, hookups are not available.  The largest campground in the park is Twin Peaks Campground.  The park is open all year however, summer tempratures(around 105 degrees) tend to drive most RVers out of the area.  Winter tempratures are just fantastic(50 to 70 degrees) so make your visit between October and April.  The campground is located just a mile from the Kris Eggle Information Center. 

There is no public transportation available in the area.  Access is by foot, bicycle, or your own vehicle.  During the winter season van tours of the Ajo Mountain scenic drive are offered, check at the Kris Eggle Visitor Center for additional information.  The dirt roads in the park are great for jeeps.  The park has two scenic loops that are all dirt and well suited for jeeps.  Ajo Mountain Drive is a 21 mile loop.  Puerto Blanco Drive is a 41 mile look that circles the Pueblo Blanco Mountains.  Off roading is not allowed in the park.
The park entrance fee is $8.00 for a week-long vehicle pass.  Please see the NPS website for more information.
