Odd, yet familiar. Overly filmed/photographed freeway exit off of Interstate 15, on the way to Las Vegas, NV. Zzyzx Road crosses Interstate 15, and dead-ends in both directions. Remote desert research community: Desert Studies Center run by California State University. Not much else.
On the north side exit of Zzyzx Road, the pavement becomes dirt about 4 miles from freeway. a wide desert wash and maybe decent for camping. Sand could be an issue for RVs, so beware of rugged terrain.
The south side of Zzyzx Rd, paved road stops at the research center and becomes a dirt road. The through route, to Old Government Road, is a one lane, unpaved route.
