Johnson Valley OHV Area Open Desert
Home of King of the Hammers desert racing
Johnson Valley spreads 188,000 acres of wide-open Mojave Desert where the only rules are basic desert courtesy and not getting stuck alone. This is where King of the Hammers ultra4 racing happens every February, leaving behind gnarly rock sections like Aftershock, Chocolate Thunder, and Back Door that separate pretenders from contenders. The terrain ranges from smooth high-speed washes perfect for overlanding to technical granite boulder gardens that’ll test every inch of suspension travel.
Difficulty varies wildly depending on which trails you choose—families cruise the main washes while hardcore rock crawlers tackle the competition courses. Any high-clearance vehicle works for basic exploring, but serious technical sections demand built rigs with lockers and armor. Open year-round but brutally hot May through September. No permits needed, but bring everything including water, fuel, and recovery gear. Cell service exists near the main camping areas but fades fast in the backcountry. This is raw desert freedom at its finest.

Frequently asked questions
Can a stock Tacoma or 4Runner handle Johnson Valley, or do I need a built rig?
A stock high-clearance 4WD truck will get you through the moderate desert tracks just fine. The gnarlier rock crawl lines are where built rigs shine, but you're not forced onto those — 188,000 acres means you pick your poison.
When is Johnson Valley closed, and should I avoid summer completely?
The area is open year-round, but summer temps regularly hit 110°F+ in the low desert — that's engine and human punishment. Stick to October through April; winter weekdays are the sweet spot for light traffic and decent temps.
Do I need a permit or OHV sticker to ride Johnson Valley?
No permit required and no day-use fee — it's BLM open desert. California-registered OHVs need a current CA OHV sticker; out-of-state rigs running on public land don't require one, but check current BLM regs before you go at blm.gov.
What's the hardest section actually like, and what should I be ready for?
The rock canyon lines — the same ones used in King of the Hammers — are legitimately brutal, with loose boulders, ledges, and tight lines that will flex out a stock suspension and punish tires. Lockers and a skid plate setup are not optional if you're going deep into the technical canyons; a spotter helps too.
How far is the nearest gas from the trail, and is there any water out there?
Yucca Valley is your last reliable fuel stop, roughly 20-30 miles from the main staging area — fill up there. There is zero water in the open desert, so bring everything you need; plan on at least a gallon per person per day minimum in cooler months, more in any warmth.
