The Mojave Road or Mojave Trail is a historic route and present day dirt road across what is now the Mojave National Preserve in the Mojave Desert in the United States. This rough road stretches 140 miles (230 km) from the site of the old Fort Mohave (on the west bank of the Colorado River, roughly 10 miles southwest of Bullhead City, Arizona) to the site of the old Camp Cady (on the west bank of the Mojave River, roughly 12 miles northeast of Newberry Springs, California). A four-wheel drive vehicle is required for all but a few short stretches of this road, which is unmaintained.
