Thanks for the quick responses. Let me be more specific to see if you think these parks would be full when I would like to stop in. None if these would be on a weekend and all would be mid March. Joshua Tree, Silverwood Lake SRA, Red Rock Canyon(drive ups available here), Millerton SRA. I will be driving to and from the Pacific Northwest to Phoenix for the Nascar race on March 15 and was hoping to have a not too set drive plan in place and just stop wherever and whenever. Is this even possible at California Parks?
Also, each stop would only be for one night.
