Found this site while scouring Google Earth for free places to sleep on our roadtrip. It’s technically not an established “site”, just a dirt road that stretches for miles into the Lemoigne Canyons.
A 4x4 vehicle is required, though the clearance is more important than the 4WD is. If you have a truck or a 4Runner, you’re fine.
There’s a sign at the beginning of the trail that says something along the lines of “no camping within one mile of the road” (I forgot to add a photo, so please leave more info on this if you camp here). It’s in the middle of nowhere, so camp at your own discretion and leave no trace.
We travelled about a mile down the road until we found a beautiful flat spot to camp. I recommend this site only to those who also sleep in/on their vehicles, as there’s no established places to set up a tent. That said, it’s an absolute gem if you can make it. The feeling of being so alone in the wide open is surreal.
Emigrant campground is literally right down the road, which has established bathrooms, trash cans, and parking spots. Therefore, I can only recommend Lemoigne Canyon to those who want to camp away from people off-grid—which is exactly what we were looking for.
