You can camp for free in our BLM short term camping area.
There is a camp host at the entrance. I would arrive before night fall as it is hard to follow the dirt roads and find a site in the dark.
This webpage will give you all the information you need to know.
Long Term BLM Camping
This is for 7 month camping for only $180 (at the time of this writing).
Again I would arrive before dark as you will be driving through the desert.
This webpage will give you all the information.
