Castle Mountains represents some of the most unique elements of the Mojave Desert. Nestled between the Nevada state line and Mojave National Preserve, the nearly 21,000 acres of Castle Mountains boasts Joshua tree forests, unbroken natural landscapes, rare desert grasslands, and rich human history. This intriguing area provides serenity and solitude from nearby metropolitan areas.
You can approach Castle Mountains from Walking Box Ranch Road off of Nevada State Rd 164 (Nipton Road) or from several unnamed dirt roads off of Lanfair Road in Mojave National Preserve.
