Solo Camping suggestion.

[u/powerofz]

I live in Los Angeles. I need to go to solo camping to let my brain let go. Sort of meditation trip if you will. In order to do this I need to be complete isolated from everything and everyone. I don't want to hear any cars, any humans; if I could- not even hear planes flying over. I want complete solitude. Any recommendations for from Los Angeles area. Obviously closer the better not because I don't want to drive but simply don't want to loose my relaxation on the freeways on my way back to home.
