Nestled just west of the Mojave Trails National Monument, the aptly named Sandbox is a short yet dynamic offroad trail that serves as a link between Manix Wash and AC9476. For most of its length, this route offers an easygoing ride over relatively flat terrain, featuring gentle whoops, mild washboard, and scattered rocks no larger than a clenched fist. However, don’t be lulled into complacency. The western end of Sandbox delivers a formidable challenge. Nearly a quarter-mile of deep, loose sand awaits, eager to swallow tires and sap momentum. Here, four-wheel drive and aired-down tires aren’t just recommended; they’re essential for making it through without getting bogged down.
At its easternmost point, Sandbox may give the illusion of continuing beyond AC9476 and winding into the mountains. However, as of 2019, that section has been decommissioned as a legal motorized route. Users should respect this closure and stick to designated open routes only while enjoying this unique slice of the Mojave Desert.
There is plenty of flat, open land one could utilize for camping, but no existing campsites exist along this trail.
