A roughly 21,000-acre desert monument in the eastern Mojave with Joshua tree forests, open grasslands, and a quiet setting.
Near Barstow, CA
This National Park Service monument in northeastern San Bernardino County protects a remote stretch of the eastern Mojave Desert. Its terrain includes Joshua tree stands, large areas with little human development, scarce desert grassland, and a long record of human history. The monument sits between the Nevada border and Mojave National Preserve, and visitors can see the Castle Peaks from Walking Box Ranch road. Access is by unpaved routes, so a high-clearance four-wheel-drive vehicle is needed, and there are no developed campgrounds. Facilities are minimal, and the area suits visitors who want solitude.
