Least Visited NPS Units: Pipe Spring National Monument

In the northwest corner of Arizona, the Arizona Strip is a remote district, cut off from the rest of the state by the Grand Canyon. The one main road across this region is Hwy 389, though most tourists prefer Highway 9 to the north (in Utah), as this crosses the spectacular landscapes of Zion National Park. So not many people pass by Pipe Springs National Monument, a small place protecting a well preserved Mormon pioneer fort (known as Winsor Castle), dating from 1872.
