Johnson Valley OHV Network
Birthplace of King of the Hammers racing
This is where Ultra4 racing was born, and one lap through Johnson Valley’s 240,000 acres explains why. The Mojave Desert sprawl offers everything from wide-open hammer trails perfect for triple-digit runs to technical rock gardens that’ll humble any rig. Soggy Dry Lake serves as base camp for the annual King of the Hammers, but year-round this remains California’s premier open OHV area. The Chocolate Thunder section tests rock crawling skills, while the outer loops let you stretch your legs across classic desert terrain dotted with Joshua trees and granite boulder piles.
Stock vehicles are welcome on the easier trails, but the technical sections demand serious modifications — lockers, long travel, and armor are standard fare. Spring offers perfect weather and wildflower blooms, though any time outside summer works. No permits needed, and dispersed camping is encouraged throughout. Bring plenty of water, spare parts, and recovery gear — cell service is spotty and help is far away. This is raw desert wheeling at its finest, where you can push your rig’s limits without artificial constraints.

Frequently asked questions
Can a stock Tacoma or 4Runner handle Johnson Valley, or do I need to be built up?
Stock rigs can access a good chunk of the network — the flatter desert runs and moderate trails are totally doable with a capable stock 4WD. If you're chasing the technical rock sections like those used in King of the Hammers, you'll want at minimum a lift, skid plates, and aired-down all-terrains. Know your rig's limits before committing to the harder lines.
Is Johnson Valley open year-round, and what's the weather like in summer?
The OHV area is open year-round, but summer is brutal — daytime temps regularly hit 100°F+ in the low desert sections. Stick to October through April for anything beyond a day trip; spring and fall are the sweet spots for multi-day runs.
Do I need a permit or are there any fees to run Johnson Valley?
No permit required and no entrance fee — it's BLM open riding area. Dispersed camping is free. If you're there during King of the Hammers event week in February, the area gets heavily managed and access restrictions apply, so check BLM notices before you go.
What's the hardest section of the network and what should I actually expect?
The Hammers trails — Backdoor, Chocolate Thunder, and similar lines — are the gnarliest zones, with large granite boulders, off-camber ledges, and loose rock that will punish underbuilt rigs and inexperienced drivers. Expect potential pinch points, hard landings, and situations where a spotter is not optional. If you're new to technical rock crawling, run those trails with someone who's been there before.
How far is the nearest fuel stop, and is there any water on-trail?
Yucca Valley is your last reliable fuel before heading in — fill up there, roughly 20-30 miles from the main staging area depending on your entry point. There is zero water on the trail; bring everything you need for the full trip, plus extra.
