This arch is located in Organ Pipe Cactus National Monument.
See Ajo Mountain Arch. Continue past Ajo Mountain Arch
on the route which turns to the right and starts to steeply ascend
toward the Mount Ajo ridge. Look up among some breccia
towers to see Ajo Train Whistle Arch. Although you may be
tempted to hike through the towers directly toward the arch, stay
on the route which leads you to the arch at about 3.5 miles from
the trail head and at UTM coordinates 12S 340879WE 3543262N
at about 3950 ft. elev. From this arch, you can continue up to
Mount Ajo, another mile+ and over a thousand feet above. When
you return, the most scenic route is via Estes Park, which
contains many excellent Organ Pipe Cactus specimens.
